Question about 2002 Pontiac Sunfire

1 Answer

Car stalls at idle

My 2002 pontiac sunfire is stalling at idle. It gives me the "trac off" light before it decides to stall, and only stalls at idle (such as at traffic signals). If the trac off light is on, the automatic transmission begins having trouble shifting gears during acceleration. The trac off light may show up with or without the check engine light, but both lights are inconsistent. The problem only starts showing up after a period of fifteen-twenty minutes of driving, and may resolve itself temporarily when the car stalls and I restart it.
I have no idea what could possibly be causing this.

Stalling at low speeds for a 2002 Pontiac Aztek


Does the battery light come on before the engine dies, or after ?
After is normal because the engine is not turning the alternator.
Is the check engine light on when the engine is running ?
Common causes for stalling are a dirty throttle body or faulty idle air control valve.

You definitely have a faulty MAF (mass air flow) sensor. The MAF controls the idle of the car that when it's faulty an erratic idle may occur. You may even end up stalling during take off so have the MAF replaced. It is located on the throttle body.

1999 Alero stalling and trac off light coming on


does the rpm motor kick down? you may need to check your vacuum hoses, and also you may want to check your exaust, sounds wierd but that can cause the car to stall at times.as for the traction light, your hitting the brakes to hard. try slowing down a little slower while stopping, and keep distance for saftey.. if you can take it a little slower at lights and turns, without braking hard and it stops stalling.
