it will idle alittle high until you come to a near stop, your IAC does that. try cleaning it and seeing if that helps, also resetting the ecu if you havent done it yet.
Can a good programmer get around this? Its annoying as hell with my cams, as it takes forever for the car to idle down (and never does when its rolling) thus making me wait to hear that camming sound

JD did u notice an increase in idle rpms when u got ur exhaust? cuz now i idle @ 1050 warmed up

None at all. The car was running great before this TB install. It still runs great, I just cant figure this problem out and its annoying the hell out of me. LOL

Well mine idles around 1100 till I come to a stop then it drops to 800. Don't bother me, thats what Ford intended, it always did that before you just never noticed it because it wasn't as pronounced. With a tuner you can set the idle, but as far as setting it while the car is in motion I don't know.

no codes. If you've got a code then somethings wrong. unplug your battery for 15 mins and see if it comes back.
