Hey guys, new to the forum. Working on a 1984 Mustang GT AOD with the CFI. The idle doesn't want to stay where it should be. This is an intermittent problem and can not duplicate it all the time. Also when the car is under acceleration it seems to hesitate for a split second then it works fine. That too is an intermittent problem. I have cleaned out the throtte body, changed the egr valve and ran a fuel treatment through it. I just purchased a TPS to install today hoping that may fix the problem. Any suggestions would be greatly appreciated. Car has sat most of its life. Only has 63,000 miles on it. Marti report in hand. I had previously owned an 85 GT but it was a carb car and I never had this issue. New to the CFI thing. Having problems finding a mechanic that is familiar with this system. I am trying not to swap to carb but if I can't figure this out, I am going to. Any suggestions would be greatly appreciated.
