Question about 2001 Oldsmobile Alero
My 2001 alero dies when i hit the breaks and try to stop for a light or slow down to turn.
1-i changed the Idle air control valve.
2-i cleaned throttle body.
3-i changed spark plugs.
none of this helped. Sometimes the car would just die while in idle and sometimes i would try to take off but when i hit the throttle the RPM dips quite a bit before it goes back up.
Any help would be highly appreciated. thanks in advance

The two most likly causes of your Idle problen are, low fuel pressure. try installing a new fuel filter. Or the other one is the Air Idle control valve, can cause the exact problem you discribed with a cold engine. Fuel Injection engines do not have a choke like carburated engines do. So the idle is computer controled thru the Air idle control valve.

hard start is AM is most commonly caused by a defective fuel pump pressure check valve, the other stall is issue is covered by the following procedure.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

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.

When did you last change the spark plugs, distributor cap, ignition wires, ignition coil, fuel filter, or the fuel pump? Any one of these could causing your care to stall. Also, have you been using regular gas or premium as premium gas can cause your engine to not combust properly if it wasn't designed for premium
