1993 Ford 5.8l Idle Air Control
This engine has less than 80k, and obviously has not been driven that much. Idle was very rough and I pulled the IAC and cleaned it. Idle improved considerably, but still isn’t smooth as I think it should be, especially at a stop light. I replaced the vacuum hoses a while back just because. What else should I be looking for here? A new IAC, or some other sensor? I didn’t clean the throttle body.
