I have a 1999 Oldsmobile Alero. It frequently stalls and the trac off light comes on occasionally. When my car is sitting still, like at red lights, it stutters, then hesitates.
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.
The trac off light is usually caused by a faulty wheel speed sensor or wire. Your wheel speed sensor is located on the wheel hub on the Alero. It has to be replaced as a unit and runs about $120. Your ABS light usually will come on as well. Check into this. Stalling... Check the catilatic convertor. If it is plugged it will make your exhaust smell rotten and can cause stalling and rough idle. Otherwise ignition or fuel system.

I didn't even think about my vacuum hoses. my rpm doesn't ever drop below 1, but it jumps around a lot when my car is about to stall.
