Check for leaks in the intake manifold or a poor fuel pressure situation.
Your Chevrolet Cavalier 97 might stall when going downhill because it has a bad fuel filter. It could also be the spark plugs misfiring.
There are a couple of reasons a 1991 Chevrolet Caprice may stall out. The car may need a new distributor cap or the plugs may need changed. A mechanic will be able to determine the causes of the stalling car.
with me it was the o2 censer
Had a 1995 Cavalier with a similar problem. It was some type of solenoid on the transmission (automatic). Cost about $500 to replace at the dealer.
There could be a couple causes . The first would be the oxygen censor isn't working properly and the other is the coil pack is probably going out.
It needs a tune-up.
There's a high pressure switch on the power steering line that activates when the steering wheel is turned all the way in any direction. This activates the AC compressor, which raises the RPM's. If the switch is not working, then the vehicle could stall.
Year, Make, Model, engine size please. possibly an ignition or sensor (electronic part).
it sounds like ur clutch went out in it.
If it stalls at idle or when slowing down, it could be a fuel filter. Or it could be the ignition control module.
Possible fuel filter, fuel pump sock fuel pump, Ignition module are the tops off the top of my head.
Your timing could be off.
