86 t-type. When the car starts up, she idles fine. About almost a minute of warm up, she idles up, then down, then up, then down, like the IAC is out of wack. The car has a brand new IAC, and a local mechanic that is good with these cars adjusted the idle as follows.
Unplugged the IAC, adjusted the idle screw so that the car would idle at 550 rpm's, then plugged the IAC back in.
Any suggestions?
