Question about 1997 Pontiac Grand Prix

1 Answer

Sputtering when accelerating

My grand prix has been in the shop numerous times for this problem and the mechanics can't seem to figure it out. The car sputters when accelerating and/or going uphill. Spark plugs were changed, fuel pump and filter changed and the converter was cleaned out. Do you think the converter should have been changed all together? i have been getting all kinds of tips from "backyard mechanics" but no dice! what do you suggest?

    I also have the same problem. I am leaning to the fuel pump resistor-fuel regulator-or valve train, but as soon as I get it fixed this car is gone. To many problems.

I have a 2004 grand prix, When you are driving down the highway, and you take foot off gas, there is vibration


Hi Cheyenne:
- For the vibration, I'd be checking universal joints or CV jounts.
- Sounds like you've got your brakes figured out already. Time for some maintenance.

Grand prix sputtering


Have the computer scanned for trouble codes. If none are present, have fuel pressure checked-could be a failing pump or clogged fuel filter. If any codes, follow that up first.

2001 Grand Prix SE tranny trouble.


You can't use those two words in the same sentence when talking about transmissions. Best is new (rarely done) next is a rebuild (most times if from a good reliable shop, good but not cheap) then there is the used unit from a scrapyard..cheaper than either, but if it doesn't work, you get to pay r&r as many times as it takes, even if the yard guarantees it. (only way I'd do that is if I owned another identical car that I had driven and knew for sure the unit was good.

Abs and tcs off lights are on,


These lights are on because the system has a fault and it has disabled itself, so you have no anti-lock brakes or traction control right now, you will have to have the system tested for trouble codes by a shop with the proper test equipment, a GM dealer is your best bet.
