Episode Transcript

Speaker 1 (00:01):
Meet Bob. He's a four time tire rotation champion. When
he was a baby, his first words were automatic transmission fluid.
Bob's so cool he has engine coolant running through his veins.
And then there's Kyle, also known as Premium Unleaded. Legend
has it that Kyle can change your oil with his
toes and that he can tell your tires ill pressure

(00:24):
just by how you're walking. He's Bob, He's Kyle, and
every Saturday morning they morphed together to form the greatest
superhero known to man. Mister Mechanic check engine lights don't
stand a chance. This is the Mister Mechanic Show on
eleven ten, kfab.

Speaker 2 (00:45):
Great Saturday morning to This is a Mister Mechanics show.
Five five, eight, eleven ten is the numbers to get in.
This is an interactive calling show. If you haven't heard
it before, you're driving through the area. You have the questions,
we'll give you our answers to what the problem is
or the top couple answers.

Speaker 3 (01:03):
Uh.

Speaker 2 (01:04):
You know they got that project. We were talking a
little bit before the show that that's a lot of
car shows out there, a lot of project stuff out there.
It's other than today it's getting kind of warm, but
after that it's gonna get cool, and that's when the
car shows got go on. So Kyle's next to me
as always, Kyle, you heading out to a car show.

Speaker 4 (01:25):
Today, No, I'll be heading to my garage, which is
a car show in itself.

Speaker 2 (01:29):
Yeah, yeah, yeah, right.

Speaker 4 (01:30):
Eventually this project will be done.

Speaker 2 (01:32):
I have a certain limit of just the temperature of
what I'm gonna go and see. So if you drive
by one, I'm done. Yeah. If it's nice, I'm stopping
in and looking around.

Speaker 4 (01:43):
Oh yeah. Car shows are great, especially like the small
town ones like I used to, you know, before I
got really busy with this project. Every Sunday I just
go drive around. You find out where the car shows
are and whatever small town get out of the city.

Speaker 2 (01:57):
They're gonna have good hot dogs. They are something to eat.
There's always good. There's always something. Yeah, there's always something
good to eat. And then you kind of hit it
around lunchtime. Yeah, for sure, and you get to see
what I see a lot of interesting stuff that comes
out of people's garages you never see prior to that.
Oh yeah, and a lot of make it up as
you goes, you know, which is what what I think

(02:18):
that's what you call what you have? Or no, no,
that's the rest, not that, not that the rest of
mod Those are expensive ones now.

Speaker 4 (02:26):
Now yeah, it's just just a weekend Warrior project.

Speaker 2 (02:30):
Yeah. No, the the ones that they damp dump all
this stuff out, and you go out and you just
start welding stuff on and make it look cool. Rat rods.
That's what I was gonna say. Oh yeah, I've got
Not all of them looked that way, but some of
them do.

Speaker 5 (02:43):
So.

Speaker 2 (02:44):
But hey, we got a couple of calls. Let's jump
right into it. We got Frank with a twenty nineteen
f one fifty Frank, what's up today?

Speaker 5 (02:51):
Well tell you what, guys, I listen see every week,
really really miss you. I've got IF.

Speaker 3 (03:02):
Twenty nineteen.

Speaker 5 (03:04):
It's got the six cylinder in it, and I'm about
to change spark tuks. Okay, what do you recommend for
Spark books?

Speaker 6 (03:14):
Oh?

Speaker 4 (03:14):
We equivalent just a good motorcraft plug. Yep, yeah, that
should do. Hello, I'm here, we're here.

Speaker 2 (03:22):
Oh okay, we're here.

Speaker 5 (03:25):
What do you did you hear me?

Speaker 2 (03:28):
Yep? I can hear you. Great.

Speaker 3 (03:30):
Okay, So what do you.

Speaker 5 (03:34):
Recommend for Spark books.

Speaker 2 (03:37):
We're suggesting going back to the uh, the original motorcraft plug,
m any any more craft anymore. We try to stick
with what it came out with. I mean, and there's
other brands that are okay and don't have really an issue,
but we just find that we have less issues if
we stick with ac Delco on a GM, Ford on

(03:59):
a Ford and you know, Asian cars get n GK
or yeah, and then for the Europeans bosh for the Europeans.
I don't know why, but if you throw a BOSH
in there, it seems like you have.

Speaker 4 (04:11):
An issue, like you didn't. You don't think that a
spark plug has that much thought behind it, but I
mean it does. You try putting auto lighte plugs in
a Toyota and all of a sudden you're gonna have
some funny things happening.

Speaker 2 (04:23):
Yeah, yeah, okay.

Speaker 5 (04:26):
Let me ask you this, what about those spark plugs
with the dual spark resistors.

Speaker 4 (04:34):
Don't mess with them.

Speaker 2 (04:36):
They're a gimmick there, They're they're a gimmick to get
you to buy what they want.

Speaker 4 (04:42):
Yeah, And I mean they've always got a race car
on the commercial, which is fine for those guys because
they're just gonna throw them away anyway. But longevity wise,
I see more of those plugs come in which just
build up and foul on them. That you got too
much of a resistor inside there. I mean, you don't
need it. I mean, a spark plug is simple. It
hasn't changed in one hundred years.

Speaker 5 (05:05):
What else should I do at one hundred and ten
thousand miles? I've already changed completely changed.

Speaker 3 (05:13):
The and it frees and.

Speaker 5 (05:23):
Kept the glory the.

Speaker 4 (05:26):
Thermostat sure, Okay.

Speaker 2 (05:29):
I would probably go through in Kyle and probably go
do through gearboxes. Yeah, gearbox I mean your you're differential
is probably going to be semi it's going to be
full synthetic. So you could go through and change all
that at one hundred and ten, the transmission, transfer case, gearboxes,
and you'd be done for another one hundred and ten. So, yeah,

(05:50):
you don't have to do it all once. You know,
maybe do a little here, a little there, you know,
just get you know, make it within a few thousand miles, you.

Speaker 3 (05:57):
Know, and and box or in right.

Speaker 2 (06:01):
Yep, yep, and you know maybe maybe transmission things like that.
You know, the coolings you've already done, so those are
pretty good for leaking water pumps and hoses, so maybe
you dump the hoses already at that time.

Speaker 5 (06:15):
So all right, something else is jumped in my mind.
Can you buy those for bugs at like one of
the out of parts store if you have to go.

Speaker 2 (06:28):
Yeah, yeah, they all stock them. Yep, they all stock them.
They know they got uh they got Ford guys or
Chevy guys that if they don't have what calls for there,
they they ain't buying it, yep. And uh so no
they stalk it all. But whether they have them all
you know at that time, you know, but they should.
Six of them is not that tough to keep in stock?

Speaker 4 (06:49):
Yeah, you won't have any problem.

Speaker 2 (06:51):
No, get yourself. I think that's what we got to
pull the intake on.

Speaker 4 (06:55):
Is it off the top of my head, I don't know.
I don't know on that six.

Speaker 2 (07:02):
Yeah, if you got to pull the top of you
got to pull the upper plumum. Make sure you get
a gasket for that too. Those O rings that start
off round and stuff just get flat over a period
of time, and you don't want to create a sea
or a leak. So yeah, all right, we're gonna head
over to Bob. Bob's got an No. Six Toyter Corolla. Bob,
what's up today?

Speaker 3 (07:22):
This is your old buddy, Bob. Hey, Bob, my son
loves toyo to. You know that you fixed the heat
shialed on the gas tank car?

Speaker 2 (07:32):
Yeah?

Speaker 3 (07:32):
Yeah, got two hundred seventy thousand on it. I speed
manual transmission. Okay. I took it out to the golf course,
you know, all Interstate in West Dodge, sixty sixty five,
no problem. Pulled into the the golf course on one

(07:52):
hundred and sixty eight, and as I'm making the right
hand turned into the I get just a violent shudder
and shake. I mean not a shimmy, not a wobble,
I mean a violent like the whole front end just dropped.
I go, oh, well, maybe I blew a tire. So

(08:13):
I limped it in the parking lot, got a park
got out. Tires are all fine. Okay. I get one
of the guys.

Speaker 7 (08:23):
I back it.

Speaker 3 (08:25):
Back at you. I'm thirty forty back and forth. He's
a looking front ends no problem, So I'm looking. I
goes well, I got Bob on your tow truck on
speed dials, and I goes, well, okay, what what am
I gonna tell him, let's I'm gonna play golf and

(08:49):
think about it. So anyway, got done, and so I
drive it around the parking lot. Everything's fine, no clicking,
no noise, no wobble. So I take I take Pacific
Street back in. I figure i'll get closer whenever sucking
breaks C B joiner whatever. You know, it's closer and

(09:13):
I can get it off the road to I'll be
coming toward. I kept on going, got the ninetieth and
I goes, well, it's still running. I'm twenty five thirty miles.
No noise, and I goes, well, I take it to
the shop. What are you what are you going to
look at?

Speaker 7 (09:33):
You know?

Speaker 3 (09:33):
So I go, well, i'd limp it on home, got it,
got it home. Check the right front tire, it's warm
up the rim the fuck it's warm. The left front
is warmer. It's hot, but I mean not extremely. I'm
just lost because the BIG's running fine right now. The

(09:57):
only other thing was in the mornings when and I
just started up, it would miss a little bit. But
then the clear up. Is it possible that if that
thing could spark plug or coil, pact could have just
shut down and with the four cylinder, you know, would

(10:17):
it make it vibrate? I mean this, I thought the
thing was going down on the cement.

Speaker 2 (10:25):
Yeah, well hang on second, Bob, I gotta kick a
quick break and then we're going to discuss it between
us and we canna come back and give you an answer.
Be back in a minute.

Speaker 1 (10:33):
Joseph stalin Canada, sweeted Barnie Fidders, What.

Speaker 2 (10:39):
Do these things all have in common?

Speaker 7 (10:43):
So shut.

Speaker 8 (10:47):
This November. That's only one way to make your car
great again.

Speaker 3 (10:52):
And that's by voting for mister mcgannick, America's answer.

Speaker 2 (10:55):
To squeaky diming belts.

Speaker 8 (10:57):
With mister mccannon, you'll be able to roll your window down.

Speaker 9 (11:00):
Again and roll through those stop signs without worrying.

Speaker 1 (11:03):
About offending someone. This November, vote for mister mcganick America's mechanic.

Speaker 8 (11:13):
Isn't it time we shared the road? Are you tired
of only one percent of drivers getting to use the
carpool lane while thousands of innocent mothers and babies and small,
insecure men are forced to wait in traffic This November,
It's time for the drivers to take their roads back.
I'm Barney Fenders and a vote for me is a

(11:35):
vote for the free gasoline to everybody. Everybody gets free
gas if you vote for me, free gasoline, free oil changes,
free windshield, wife of fluid.

Speaker 2 (11:47):
Who's going to pay for this, Barney, I'll tell you
who we are.

Speaker 7 (11:53):
That is, unless you vote for mister mcganick.

Speaker 2 (11:57):
He's the only one who can save us from cottage social.

Speaker 8 (12:03):
I'm a good kind of socialist.

Speaker 2 (12:05):
Okay.

Speaker 1 (12:06):
Stop.

Speaker 8 (12:06):
Don't believe the lies, the hatred, the mechanic propaganda. As
your mechanic, I promise to fulfill my promises, just like
I promised to fill every pothole in America. Vote for me,
Barney Fenders the pothole filler.

Speaker 2 (12:22):
Fill every bottle up.

Speaker 8 (12:23):
That's impossible, body, It's not impossible if you.

Speaker 4 (12:26):
Would have to drive on.

Speaker 3 (12:29):
A thing, that's all.

Speaker 8 (12:30):
Okay, stopping, come on, you know stop what I got information.
It's illegal to roll through stop signs.

Speaker 2 (12:36):
Okay, you.

Speaker 8 (12:39):
Get ready, get I'm great.

Speaker 2 (12:43):
Vote for me because I'm great. There, I mean, I mean,
mister mechanic is great, not me.

Speaker 3 (12:47):
I'm not.

Speaker 1 (12:47):
I'm not mister mechanic.

Speaker 2 (12:51):
Are you, Bob, you're still there?

Speaker 7 (12:54):
Oh?

Speaker 3 (12:54):
Yes, all right, we got it.

Speaker 2 (12:55):
We got a couple of answers for you. We got so,
but first we need to know. So what did you shoot?
You shoot? What a seventy out there the golf course,
ten under seventy?

Speaker 3 (13:07):
You lost? We lost our match.

Speaker 2 (13:09):
I was okay, all right.

Speaker 4 (13:11):
So here's here's well, I chalk all that up to
this Toyota Corolla.

Speaker 2 (13:17):
Yeah, if you didn't have this problem, you'd have shot
clearly into the sixty five something like that.

Speaker 3 (13:21):
So anyway, oh, got you?

Speaker 2 (13:28):
All right? All right, So what we're talking about. All
this happened when you turned the corner. So what we're
thinking is is you've got an axle problem, an axle
problem that was binding up. I've seen also motor mounts
that can shift when you kind of turn to the
right and everything kind of shifts to the left and

(13:50):
binds things up and kind of does it that way.
So motor mounts are something you want to you know, check,
you know, put it and dry, put in reverse, moving
back and forth, see if they go anywhere. The third
thing would be if a caliper the bolts fell out
or something like that, and the caliper fell against the
wheel and then for some odd reason it goes back

(14:11):
to where it should be. Which I've also seen before.
Most time they hit the wheel and stay there. Yeah
you get stuck. You get stuck, but not all the time.
It just kind of depends. But I think you're more
likely that you got an axle. I don't know that.
I would if we can inspect it and take a
look at it and see if he's anything obvious. But
I think you need to wait and see if maybe
it happens again. Maybe it was just caught in that

(14:32):
CB joint problem at that time and it's going to
show itself again. Probably, It just depends on when.

Speaker 3 (14:39):
Well, yeah, I know these things don't fix themselves.

Speaker 2 (14:43):
And look underneath it, see if the boots are exposed,
to see if the balls in the cages are all exposed.

Speaker 6 (14:51):
Maybe the boots.

Speaker 4 (14:53):
Maybe you lost all your grease and you're running it dry.

Speaker 2 (14:55):
Yeah, maybe the boot's torn. If so that that gives
you an idea that aha, there it is. I need
to place that axle. So yeah, try that.

Speaker 8 (15:03):
I was.

Speaker 3 (15:05):
Thinking drive back too, or that left front caliper I
would replace that. I don't know, five six years ago, sure,
but I mean it gets that wheel was it was
warmer than the right hand site. I mean that's not
completely hot to the touch, but but hot, you.

Speaker 4 (15:24):
Know, right right now to get it apart, you know,
just pop your wheels off. There. Gave everything a good
look over. I mean that's easy.

Speaker 2 (15:32):
Yeah, I'll tell you what. Visual inspections a lot of time,
just reveal a lot of things. So I did take
a quick peek. If you don't see something and it
happened again, bring it by. We'll we'll find something for you.

Speaker 3 (15:45):
Well, that's just I mean, this is fifteen to twenty
miles driving that thing on the Interstate once Dodge. I
mean that sixty seventy. You know, it was fine, and
that's that's why I was thinking. I drove it around
the parking lot before I headed back. I goes, you know,
I should hear something there, rolled the windows dound in here,

(16:07):
Andy's clicking right, turned right. I was thinking maybe CB
joint two, but I mean, never know it was. It
wasn't a shake. I mean it was a shudder. Yeah,
the whole car was sure. You know I'm down on redoms. Yeah.

Speaker 2 (16:25):
Well, welcome to car repair. When it doesn't act up. Yeah,
that's our that's our daily life. Welcome to car repair.
I gotta move on. If you need some help, we
got two tow trucks. You call us, we'll come get you.
All right, We're gonna head over to Art. Art's got
a ninety four Chevy Caprice.

Speaker 6 (16:41):
Art.

Speaker 2 (16:41):
What's up today?

Speaker 9 (16:43):
Hey, you guys, just change the ignition module on it.
The car was running, had a little issue of miss
a little bit on acceleration. The car would start and
run just great for five minutes, so it warmed up
and then it would sluggish. So I replaced the ignition

(17:05):
coil with a ac delco and it put on a
control module on it, fired it up, and it started
and died right away. So I took that one out
and put the one that was running back in. It
started up and died right away. So I just kind
of wondered, what's going on?

Speaker 4 (17:27):
M So there's ninety four Caprice. Does that have the
five to seven in it?

Speaker 9 (17:32):
It's got the three fifty?

Speaker 2 (17:34):
Yeah, okay, the distributor in the back is a distributor
in the back star okay, all right behind the water pump. Yeah,
we're trying to make sure which one it is.

Speaker 4 (17:46):
I did a million of those distributors.

Speaker 2 (17:49):
Yeah, so there's and I so did so have I
and it's it's taking me a minute to think about
all that was in there. But uh, so you're not
replacing the whole distributor. You're just replacing the module that's
in there.

Speaker 9 (18:01):
The module up is screwed under the head.

Speaker 4 (18:07):
Yeah. So again, I mean, this is we're going way
back and the addles of my conscience here to remember
all these cars. So you've got to pick up inside
your distributor that goes up to that ignition module, and
that is generally what fails is what's inside that distributor.

Speaker 2 (18:31):
Yeah, so we know, we know we changed the module
and it started and died, it ran into something.

Speaker 4 (18:38):
And I can't remember off the top of my head
how we used to test those pickup coils. But it's
a simple test because I mean there's no real computer involved.
It's going to be like a flashing test light essentially.
But I can't remember off the top of my head

(19:00):
how we would test them. But the fact that you
changed a part and things got worse and then you
changed it back and we didn't have any remedy to it.

Speaker 2 (19:10):
Would lead me to believe that our modules are okay
because it was running prior, so we know that module
is fine. So that also leads me to believe that
you got a problem in the connector, and.

Speaker 4 (19:20):
The fact that it's getting hot is more pointing me
towards this distributor because it's run off a shaft on
the back of your water pump that's gonna get hot
and leaks oil, and leak's oil fills up that distributor.
It's generally how I find them.

Speaker 2 (19:38):
It was a great compact design in theory, and it
was a terrible contact. There were terrible design based on
the seal that lets oil through from the timing cover
and it's right down in the midst of it.

Speaker 4 (19:49):
It gets it gets really hot.

Speaker 2 (19:51):
It gets stupid hot, and water and everything else gets
in it too.

Speaker 4 (19:55):
So my advice would be to take a good look
at that distributor. And if you're going to do a
distribute or you're going to do an entire tune up,
you're putting plug wires on there, you might as well
do it all because it's all coming apart to do
it anyway.

Speaker 9 (20:06):
Yeah, I already put in new plugs and wires and
good you know, steel fielder and all that stuff. So
and the good thing is what's a good disturbertor.

Speaker 4 (20:17):
To put into that the best one on the market,
I would look at there might still be an Ashy
Delco available for it. Otherwise, I mean there's patronics out there.
I mean you can look online and there's going to
be a million different ones.

Speaker 2 (20:36):
But you know, if it's easy to change for the
most part, you know, you can buy whatever you want
and go to the cheapest one, since that one is
a very large pain to change because you got to
pull the water pump and you got to pull everything out.
I personally, if it's mine, would not skimp on the price.
I would buy the the maybe not the most expensive,

(20:56):
but I buy the most quality one that you could
find look.

Speaker 4 (21:00):
For like ac Delco stuff like that. I mean, I'm
sure that there's MSD and Holly probably have one, but
I don't know if that's the direction you definitely necessarily
need to.

Speaker 2 (21:10):
Go with this car.

Speaker 9 (21:10):
Do you guys do that job?

Speaker 2 (21:12):
You bet?

Speaker 6 (21:13):
Sure?

Speaker 9 (21:14):
Okay, what kind of money are we talking about? Basic?

Speaker 4 (21:20):
You know, I haven't done one, and I mean we're
probably gonna be dollars all of three hours in replacing it.
And I mean, give or take, I mean you're gonna
be upwards at eight hundred bucks, I would.

Speaker 2 (21:32):
I would say, you're gonna be somewhere anywhere from the
eight to fifteen range. I don't know off the top
of my head, because i'd have to go see what's available. So, yeah,
if you're interested, we can nail that down. Give us
a call. We'll nail that number down a little bit
closer for you.

Speaker 9 (21:46):
Okay, that sounds good.

Speaker 2 (21:47):
All right, appreciate it. Appreciate the call. Art, appreciate you waiting.
All right, we're gonna take quick break on the mister
Mechanics show five, five, eight to eleven tens and numbers
to get in and be back in a minute. Troy,
Troy's got an oldinator voltage question. Troy, go ahead.

Speaker 7 (22:01):
Hey, yeah, hey guys, how are you great?

Speaker 3 (22:04):
Good?

Speaker 7 (22:04):
Hey? So my question initially is what's the best way
to test an alternator? And I guess the two ways
I know of are to run a meter to just
the battery post when the vehicles running, and then to
run the positive to the back of the main nut
on the alternator, and then to ground it out. My

(22:25):
my situation to kind of give you a little more
my my wife's town and country. That alternator that that
back nut is a bear to get to, but I
just wondered if that's a more accurate way to test
it than just putting it on the battery post.

Speaker 4 (22:38):
Well, I always start at the battery, Yeah, because that's
what matters in your charging system. That's your home base.
So we got to see what's happening at home base
before we worry about who's on second. So, okay, if
I take it. You have a volt meter, yes, okay,
So we're going to hook that up positive and negative,

(22:59):
and we're going to run the car. We're gonna see
what kind of voltage is coming out of this alternator.
You'll want to be if your battery is charged up,
you know, probably somewhere I think thirteen to five probably
pretty darn good.

Speaker 2 (23:11):
Yeah, thirteen to five. You've got load on it, you know, blower,
motor heater, things like that, and otherwise this should pop
up to fourteen to fourteen to five.

Speaker 4 (23:20):
And then also what I'm gonna do, Well, you've still
got that hooked up just like that, take your dial
on your vault meter, switch that from DC to AC
and you want to be reading something less than point
three tents of a vault that's going to tell you
if the stater section of your alternator is bad.

Speaker 7 (23:42):
So I've never heard of that.

Speaker 4 (23:44):
Yeah, alternators put out alternating current. Cars run on direct current,
so we have to have a diode stater that converts
alternating current to direct current. When that goes bad, you
get AC voltage in your DC electrical system, and that
causes a lot of issues. So that's a simple way.
Just switch it to AC if you got less than

(24:06):
you know, give or take what the threshold on your
meter is. I always look for less than point three
if I'm using a meter. If I'm using a scope,
I'm looking for zero. But yeah, and then from there
you'll want to test the ground to do a voltage
drop test on your ground side, and then that's about it.
If your alternator is not charging, then you'll want to
get to your back nut and see if you have

(24:28):
power from the battery.

Speaker 2 (24:29):
There, right, Because what that's what that's telling you there
is if all of a sudden, you've got twelve volts
at the battery and you go to the back of
the nut and you got fourteen to five, that tells
me you got a broken wire or a bad connection
somewhere between the allinator and the battery. Yep, that's battery, right.
That's the only reason I check it back there is
just to make sure that it's Is it dead at

(24:50):
the battery, yep? Is it dead at the aldinator yep? Okay,
that's what we got.

Speaker 4 (24:54):
That's telling you the integrity of your circuit.

Speaker 2 (24:57):
What's your problem?

Speaker 7 (25:00):
Well, we had we we we we We had about
twenty four hundred dollars worth of work done to our van.
A couple of weeks ago. We were on our way
to Utah and we broke down and we had a
bunch of coolants. So we had some coolant problems. And
we got home and I probably has nothing to do
with it, but we got home and then all of
a sudden, my wife went out to go to work

(25:22):
one day and her van wouldn't start. My My kind
of my thought on it is, this is a twenty eleven.
It's got one hundred and forty three and some change
on it mileage wise. You know, we just we just
had the radiator, you know, I mean, stuff has a
life on it. And that's why it's like maybe maybe
the alternators just finally caught up with us. I mean,

(25:43):
you know, that's that's the factory alternator.

Speaker 2 (25:46):
Yep, could be hell, the battery.

Speaker 7 (25:49):
The battery, it's only a couple of years old. I
can't remember the exact day, but it's it's it. I
think it's only a couple of years, within a couple
of years.

Speaker 2 (25:58):
And no, okay, so any lights in the national battery
light anything on that along that line.

Speaker 7 (26:05):
She said, the battery light did come on too.

Speaker 2 (26:07):
Okay, this is after it died or just why it
was running.

Speaker 7 (26:13):
So why I think it was while it was running,
because then she drove it to work. I put the
the I jumped it and got it going, and they
drove to work next day and she said the battery
light was on.

Speaker 4 (26:23):
Okay, Yeah, you've got most likely an alternator issue.

Speaker 2 (26:26):
One of the other things. One of the other things
you go want to check, and this is a Chrysler thing.
Make sure you pull the positive and positive and negative
cable and make sure you get down to fresh metal
on both the cable end and the battery. They have
they have a problem. Chrysler has a problem with electrical
arcing on the positive side post.

Speaker 4 (26:46):
They turned black.

Speaker 2 (26:47):
They turned black, and not only on the cable, but
they'll turn black on the on the battery and all
that electrical arcing will create a bad connection and create
exactly the problem that you have.

Speaker 7 (27:00):
Okay, Okay, I don't know if I quite understand what
you mean by that, but you say, get down to
bare metal.

Speaker 4 (27:07):
So when you take your battery terminals off, disconnect your batteries,
you're gonna want to get a wire brush and clean
it till it's really shiny, Yes.

Speaker 7 (27:17):
The battery terminal or the clamp both.

Speaker 4 (27:22):
Oh okay, Yeah, get a good battery cleaning brush and
just go to town on it.

Speaker 2 (27:28):
Battery post super clean, the insides of the cable lands
super clean clean.

Speaker 7 (27:34):
Okay, Okay, I got you now, Okay, And you said
I think quite get it rode down. With it running
at the battery, it should be like around thirteen to
five for DC.

Speaker 4 (27:47):
Load, right, you're around there, yeah, loaded, okay, then you
want to be fat fourteen.

Speaker 2 (27:51):
Fourteen five with it unloaded, nothing.

Speaker 7 (27:54):
On, okay, and if not, then shut it off and
dead or not not even but dead but not running.
Batteries should be around twelve.

Speaker 2 (28:06):
Ish twelve point six, usually about twelve point three each
each set point three. Yeah, each cell has two point
one volts. Time six is going to be twelve point six,
but most of them, most brand new batteries, you're going
to see twelve point three to twelve point six sitting still,
everything off on a good.

Speaker 7 (28:26):
Okay, okay, do you think, oh, is it fair.

Speaker 2 (28:29):
Too you think below that you got a bad battery?

Speaker 7 (28:33):
What's that?

Speaker 2 (28:34):
Anything below that you got a bad battery?

Speaker 7 (28:37):
Oh? Yeah, what I was going to ask? And is
it fair to to think then that if I've got
it running and my measurement at the alternator or at
the battery is less than thirteen to five, it's found
into the twelves or something, then I need to jump
over and do the alternator as a test to come
back of the alternator.

Speaker 9 (28:55):
Yeah.

Speaker 7 (28:55):
Correct, And then that's that should be that should be
fourteen's as well.

Speaker 4 (29:02):
Or yep, yeah, it should be you know, thirteen or fourteen.
Whenever you have at the battery, you'll have at the
back post of the alternator.

Speaker 7 (29:10):
Okay. And then the AC test. I can't remember did
you say that I do that with the when I
looked at the battery or the back of the alternator,
the battery battery, battery Okay, I have never heard of
that test before. That's why you really got my attention
with that one. So okay, hey, fella's time to get
to work.

Speaker 2 (29:26):
Thanks a lot, you've bet appreciate it. Cal, all right,
we're gonna head over to Don. Don's got a two
thousand and nine deep Patriot.

Speaker 6 (29:33):
Don.

Speaker 2 (29:33):
What's up today?

Speaker 6 (29:35):
It's shown?

Speaker 2 (29:37):
Oh but that's okay, Okay, you're Don today.

Speaker 6 (29:40):
Okay, they were good. Was driving down the road with
it a month ago and it started running really rough,
especially going up hills, and so I lived home. It's
not about one hundred thousand miles on him, and I

(30:01):
replaced the plugs, the coils, the camshaft sensor, and my
OBD two said the heater control circuit sensor was bad,
and so I replaced that. And when I tried to
fire it up. Oh, and then one other thing, it

(30:22):
said the ambient temperature sensor circuit was high. That was
a B one six four eight air code. And that's
about the only thing I haven't replaced. And I was
wondering what does that do? And diould that keep it going?

(30:43):
I mean, keeps the problem going. I couldn't find much
on it online.

Speaker 4 (30:50):
So your car's running bad? Is that what I'm gathering?

Speaker 3 (30:53):
Yes?

Speaker 6 (30:54):
Okay, So you started out. I mean, since I replaced
the plugs, coil and amshaft sensor and the other sensor,
it'll start run really smooth after about a minute and
a half or two minutes since he starts missing.

Speaker 4 (31:12):
Okay, So I doubt that the ambient air temperature switch
is going to have much to do with this. That's
just kind of hangs out there in front of the
radiator as you're going down the road. I mean, it'll
tell you what the temperature is outside. The car does
use that as part of the fuel strategy, but it's

(31:33):
not as important as say like your map or barrel
pressure sensor, things like that, or you know, if it
was something like that, I'd say, let's take a look
at And I'm not going to get horribly excited over
an ambient air temperature code. So we need to figure
out which cylinder you're misfiring on, or is it misfiring
on all of them?

Speaker 2 (31:55):
Well okay, yeah, John, think about that for a second.
We're gonna quick break and we'll come back talk some more.
Do you know what specific cylinder this is misfiring on?

Speaker 6 (32:06):
No, I was gonna ac is there a way to
how do you test that? Other than you know because
the plugs in it. Who it's got the coil is
the top on the top of the plug.

Speaker 4 (32:23):
So okay, So here's here's the safest way that I
can tell you to test this. So you get it running,
and it starts running really bad. You got your four
coils right there in front of you, unplugged one at
a time. Unplug one, does it start running way worse?

(32:44):
Plug it back in. It starts running better. We know
that one's working. We go to the next one. We
unplug it, no change. We know that cylinder's misfiring and
that's what's causing our problem, right, and then from there
you pull that coil out, plug it back in. Did
you get electrocuted really bad? Okay? We know we got
spark and then we just go deeper.

Speaker 2 (33:04):
But yeah, the fact that it starts off running okay,
makes me think that everything there probably is. Okay, you've
got a problem with all the other parts have changed,
like a cam sensor possible, you know those are those
were problem.

Speaker 4 (33:22):
How's the anti freeze level in this this car? Is
it's full? You don't have any leaks. You haven't been
going through any any freeze for any period of time. Okay, okay,
so let's assume that our head gaskets in good shape.
So the fact that it runs and then starts running

(33:42):
bad and you had an oxygen sensor code, I think
if you don't get any satisfaction from, you know, unplugging
the coils and finding an issue there, the next thing
I'm gonna want to look at is fuel and see
what the fuel trim is when this thing is not

(34:03):
running good.

Speaker 2 (34:04):
And I don't remember were you having? Was this running
rough and running poorly to begin with? Or these just
things that you wanted to change.

Speaker 6 (34:11):
No, Well, I'm just driving down the highway and all
of a sudden it just started going up a little
hill and you know where you have to accelerate for
a little foot into it, and it started fucking and
often I didn't know if I'd even make it all
running so bad.

Speaker 2 (34:30):
So that doesn't sound like one cylinder. That sounds like
something that's affecting everything. And these do have I bought?

Speaker 6 (34:36):
I bought the car used and the plugs were all bad. Okay, yeah, uh,
they're probably never changed.

Speaker 2 (34:45):
Yeah, but do we have problems like this? And we
changed a bunch of parts and then all of a sudden,
you got problems. You got to take a step backwards.

Speaker 4 (34:53):
And we don't know where we're starting.

Speaker 2 (34:55):
Yeah, we don't. We don't know how far to step
back on this.

Speaker 4 (34:58):
The only other off ball. I mean, these have a
lot of issues with crank sensors. And I'm kind of
curious as to, you know, because you had cam sensor codes.
And generally when I see a CAM sensor code, it's
going to be a timing issue because a CAM sensor
more or less just kind of hangs there until there's
such a time that it needs to report that this
guy ain't in time.

Speaker 2 (35:19):
Just tell us a computer or something's going on.
