When I 1st start my car (cold/warm, doesn’t matter), I need to feather the throttle a bit to get my idle to settle and stop surging. Once I get it manually “smoothed out”, I don’t have any more problems with surging or stalling. It’s just that “initial startup“ that gets the idle all wonky. I looked over the “idle“ sticky about 100 times. I can’t find the answer there. I was thinking of trying the IAC adjusting plate mod thing that I found info on. It’s a Ford part. Any thoughts?
