Can Someone help me out please!!!. I have a 1989 Camaro rs 2.8 v6 and the car stalls on me when I'm coming to a complete stop. It also starts misfiring at high speed. My car also idles kinda low when I'm just sitting still. I changed the Distributor and the IAC and no luck. I took it down to a shop near me and they couldn't figure out what was wrong with it. They said when they took it out for a drive nothing happened and the car was running fine. They didn't find no vacuum leaks or nothing like that. the car does not have any check engine light. The only time the check engine light comes on is when the car starts missing firing or when the car stalls on me. Could I just have a bad ECU?. Please help!!!
