Wont idle (Page 2/2) Patrick JAN 14, 08:56 PM It's also critical when replacing the IAC, that the air passage it controls is also completely free of crud. ViperRedFiero JAN 15, 08:19 AM Thanks. I do recall the last IAC I put in got tight while I was threading it in before it was actually seated in the throttle body. It probably bottomed out but I didn’t know it could be adjusted. I’ll make sure to check that next time fierofool JAN 15, 03:18 PM If it bottomed out before the assembly was seated, you've probably damaged it and it would need replaced. ViperRedFiero JAN 16, 02:46 PM Yeah I’ll definitely replace it. Right now I’m dealing with a poor connection somewhere between the battery and starter motor. I gotta fix it before I can move on with the idle issue
