YACT - For all the mechanics out there - Chrysler

[cornbread]

92 Chrysler New Yorker; 3.3L V6 Fuel Injected..

The problem:
When driving, at random it seems, the engine seems to suddenly lose power, running rough, then when she hits the gas, it goes back to normal.. It seems to do this at all speeds, and when the engine is hot or cold... Anyone have any suggestions, or any other questions you need to help with this?

Any help would be greatly appreciated!! Thanks

 

A cheap fix that probably would benefit the car anyway would be to replace the plugs and wires. That might even take care of the problem too. I'm not a mechanic though.

is it throwing a code?

No service engine light, so I don't think it is...

its a 92, id do a 100K service to it, and change all sparks etc. like mentioned before.

do that, then report back.

The problem is that it's a 12 year old Chrysler. The things do not have the greatest reliability record in the world and if they can afford it they should really think about a new or new to them car.

You should tell them that you're not a mechanic and tell them to go to one.

Aww come on ZV

Do the tune up as jumpr & nourdmrolNMT1 suggest. Then go to autozone and have them pull the codes. Just because the CEL is not on doesn't mean there is no code. The computer will store the codes for ~50 start cycles.

a lot of times on Chrysler products you can turn the key to the "on" position 3 times and it will spit out the code in the odometer display (if it is digital anyways)

I didn't really mean that to be a joke. The early 1990's was decidedly not a good time for Chryslers from a reliability standpoint. Chances are that fixing the car this time will be temporary at best and that more problems will begin to follow upon each other more quickly. At 12 years old, they have very likely gotten a lot of use out of the car and it's not wasteful to suggest moving on. Of course, from the age I'm assuming something like 150,000 miles too, so if the mileage is a lot less than that my recommendation might not hold.

If it were me, I'd walk away from that car.

Screw the codes... scan tools have made techs lazy.

Besides, its a 92... it might be a real b1tch to get at the connector and you'd do better to do a basic tuneup first (which you should be doing anyways) then if the problem persists to check the car's emissions system, fuel trims, fuel pressures, vacuum, etcetc. I bet its probably something as stupid an EGR that's getting stuck open mechanically... and all the codes in the world won't do you any good with a problem like that in older cars without EGR flow checks.

I know, but I was kinda hoping that the OP knew his GF's car has seen better days. The early 90's were not really good to any domestic maufactureres really. Ford had the head gasket and trans problems, Chrysler has problems with just about everything, and GM had problems too. Really, any car that age is going to have some major problems. Your point about walking away is a good one, but it would be for nearly any manufacturer, not just chrysler. They are probably the best bet for walking away though

Ignore the idiots and just run the codes
http://www.allpar.com/fix/80s-codes.html
That tells you how to do it which is so simple even the idiots could do it and what they mean. You may need to go get a haynes manual or somethingt though since a lot of those may only apply to the older cars.
