Curious if u had fixed yourself. Im having similar issue, replaced the IAC, but still doing the same thing, not sure if I need to somehow reset as I'm assuming it needs to be in the "out" position at start up limiting airflow.
Hi, started having an issue last week where i cant idle and motor won't start in neutral unless I click the shifter to give higher revs. Once started runs great but once I stop it either dies or idles very rough. In my research seems likely culprit is the Idle Air Control valve.
Anyone else...
