Question about 1988 Chevrolet Cavalier Z24
I have a 1992 chev cavalier z24 3.1L multi-port FI. when i stop at a light or sit still idling in gear the car idle drops drasticly, the electrical components slow down and the lights dim. sometimes it idles so low it stalls. i've been told to check something called the "idle air fuel control module". is this correct, if so, what are my options for repir or replacement?
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk 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.
