i got a 95 gt with the 302 and every time i start it the idle will jump from 800 to 1200rpms and when im driving and it will stay at 2000rpms when i push the clucth. im wonderin if there is idle relearn procedure for the iac or im just lookin in the wrong area. its also running the check engine light and the code is "cant control rpms". i threw a iac at it and cleaned the throttle body it went away for about 20miles and it started being stupid again.

i have a few bolts on but the motor is completely stock. i hope someone can help me out, cuz i never had to take my car to dealership to have work done on it and dont wanna start now.
