Jeff, thanks for the info. I don't have my Stang anymore, but I fought that problem for years with it. All the IAC changes, resetting computer, changes to throttle screw position, etc. never seemed to totally eliminate my problems. This is the first I've heard of the parameteres you mention. Good info to know for future reference. Thanks! ( I am already planning out my next Stang purchase for this spring...the Conturd has got to go
)
