Question about 1989 Chevrolet Cavalier
I THINK IT THE FUEL SENSOR OR WHAT Problem just started.Runs fine at high speeds,but stals out at low traffic speeds and stop lights.this only occurs when car has warmed up.Wish Iknew?????????????????????????????
It sounds like your IAC,idle air control,this unit controls your idle once your choke completally shuts off.on 2.8litre it is located right side of engine just above where your fuel lines go into your manifold ( fuel rails), it's held in by 2 screws &looks like a little electric motor, it's actually a soliniod, inside is a little pinnacle that goes in and out and is controled by the computer.good luck.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
