My 91 302 is Idling really high when its running and it has a check engine light. When I press in the clutch it idles normal and the check engine light goes away. Even while the car is in gear the problem is still there. Any clues?
It does it when it is in gear and out of gear. It does it when the clutch is disengaged. When you press in the clutch the check engine light goes away and the idle goes to normal. For some reason I am not able to get any codes at all with the reader.
