No one told me about a motor mount. It's very possible the mech that told me
about Torque Converter is wrong.
It's like going to doctors, you can get a different diagnosis each time, for
the same problem. Or else you get a "I don't know"

Not saying you made something up, The code could have been set for a number
of things, Computer related, vacuum related, wiring related or even a PCM
fault. If the lite is not on that means that the problem had corrected
itself, it is NOT a hard fault meaning the problem is not there at this
time. It would be a stored fault with a possible intermittent problem!!
Therefore if the dealer or whoever charged you a check out fee. It would
have come back as an educated guess to fix your problem or no work performed
at this time and you would have been charged for the check out time! Thus
feeling like you spent money for absolutely nothing!! There are TSB's out
that require a reflash of the engine controller that may or may not pertain
to your problem. since you do not want to specify year make and model all
you have on here is going to be a gripe that your independent/dealer can not
fix your car

I sure wish that were true. When I dropped off my Caravan for my
intermittent dying/jerking problem I told them, "I know I have a bad
O2 sensor and I've had 2 mechanics tell me it isn't the source of my
problems. I don't want to replace it at this time."

Later that morning I get a call from the dealer:

Dodge: "You've got a bad O2 sensor and a 'fuel efficiency flow'
problem with your fuel filter. Should we go ahead and make the
repairs?"

Me: "Go ahead with the fuel filter replacement, but hold off on the O2
sensor."

Dodge: "We've got a fault code on the O2 sensor, we have to repair it
before we can proceed."

Me: "Will it stop my problem with my car stalling and jerking."

Dodge: "It should, besides we can't continue to diagnose it until we
fix this problem."

Me: "I've already had two other mechanics look at the vehicle and
they've told me they don't know what is happening but they're certain
it's not the O2 sensor. One even had the car die on him with his scan
tool hooked up. He recommended I bring it to the dealer. Now you tell
me it is the O2 sensor. Are you certain this will fix it?"

Dodge: "We're 100% sure it will fix it."

Of course it didn't fix the problem. I'm still disputing the
charges...

Hi
I would like to help. What years is the Caravan,engine size and
mileage. On several occasions I see tech's change 02 sensors because
of a bad reading, for example 02 stuck High or Low along with out
range adaptive memory readings.Some techs are to quick to change a
part because they have the fault code for a certain sensor but often
don't take that extra step and check everything.It is possible that
fuel pump is playing games. A simple roadtest with a fuel pressure
guage connected to the vehicle could save you time and money. A pump
thats not working properly can make your 02 sensor seem faulty.(Due to
the lack of or to much 02 detected in the exhaust)

Max, without knowing the make/model/year, other than it's a Mopar -
Any Mopar mechanic worth his salt knows the EGR issues on the 4 cyl
engines - and knows they can be intermittent. The LEAST they could
have done is checked for a bad vacuum hose. They are VERY COMMON. It
is a WELL KNOWN PROBLEM. It costs about a buck to fix. Every Chrysler
dealership mechanic should be checking for the problem every time they
work on one of these cars - complaint or not - CEL or not.
And the dealer should be supplying the hose FREE OF CHARGE for every
one found bad. Best customer relations you could envision - "by the
way, there was a minor problem with your emission system -We fixed it
for you - here's the part we replaced - NO CHARGE - Have a good day!!"
Best buck and 5 minutes you could ever spend.

WRONG!! As I said there are reflashes out on particular model Minivans tha
require a flash of the PCM to install software that will update the engine
controller for an intermittent fault for turning the Check engine lite on
and setting a code for the EGR . Once again ...WORNG The newer model
vehicles do NOT use a vacuum controlled EGR. it is all electronic. If you
knew what you were talking about you would Know that a P0404 fault code is
An EGR postion sensor fault there fore this valve is strickly electronic
and DOES NOT use vacuum to operate the EGR valve. Try again

And that will probably happen if the dealer replaced the EGR valve on the
OP vehcile because the owner said it was the EGR due to another technician
saying that. If the valeve was bad why didnt the independent shop replace
it??? they didnt know and blew it off to the dealer

Glenn

exactly my point!! Just because a fault code was generated for a
particular
part DOE NOT mean that part is bad

Glenn

It's a '97 with a 3.8 liter and 64,000 miles. The first guy I took it
to did hook up a fuel pressure gauge and said I had proper pressure.
He's the one that had the car die while hooked up to his scan tool and
one of the guys that said the O2 sensor wasn't causing my problem.
That's another reason why I'm so ticked off at the dealer--they
replaced the fuel filter and the O2 sensor, over $400 in charges and
it didn't fix my problem.
