Re: Idle Air Control Valve
hey, if its not the IAC, maybe Tom1222 just gave you an idea. is your chk eng lt coming on, or on? try the IAC, then id look toward the TPS. I had a cougar 3.8, and a small exhaust tube (i cant remem. what egr maybe?) broke and heated the hell out of it (TPS) and it was hard to keep running at idle, but not always. hope this helped
