Idle problems..
 

Well, the stang is beginning to piss me off. I just got it back from getting her a new clutch and no my damn idle is crazy. When I come to a stop/red light my idle will sit fine for about 30 secs and then it will go from 600-1k to 400-1k and so forth...sometimes it does it sometimes it doesn't. I did an egr delete delete about 1.5 yrs back when I installed my headers and never got my car tuned and I know to some degree the egr helps your car idle. Now, this has never happened before until now. I did replaced my IAC about a month ago, so could my iac be the culprit?:confused:..Thanks for any help guys...:mad:

more then likly the battery was disconnected to let them feel safe about pulling the starter out of the way for the clutch. When they did that the ecu drained and lost its idle settings. Give it a few days or weeks and it will relearn everything and idle fine. Mine was the same way for a good 5 or 6 days.

I will follow your advice spike and see what happens...
