Heidi

I have a 1992 GMC Jimmy and when i slightly push the gas it cuts in and out. Ive tried everything i thought could be and its not it. I tried the ignition control module, the, ignition router, the map sensor, fuel pump relay, and everything ive tried hasnt helped it at all. I just changed the fly wheel it was F**ked. Do you think that maybe it threw the timeing off or what. I need help NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
