Hi, I have a 95 saturn sl-2 that has been having idle problems and stalling. The idle will rise to 2000 rpms or so when I start it then slowly come down to between 1000 and 1300. And sometimes the idle will be high and then out of nowhere the idle will drop to the normal 6-700 rpms. It also stalls occasionally. I have changed the iac, the tps, I cleaned the throttle body and the intake, I put a new map sensor on and still wont fix it. I brought the car to some guys house and he scanned it and the maps code came up but when I put it on it didn't do anything. Maybe he just had a cheap scanner. Do I need a new pcm? Or what could be the problem. Please help me, I dont know what else to do and the car is using more gas than necessary because of the high idle.
