Idle at 3000 wont stop

i recently just had my motor rebuilt with all forged parts but i cant seem to get the tune right. when i make one pull on the dyno and then let off the gas the car sits at 3000-3400rpm for about 2 minutes then drops down to normal range. what could be causing this? i got 2 codes which were TPS out of range low, and heater circuit malfunction, i changed the voltage on the tps to where it said it needed to be but the car still idles at 3000. i really need to get this thing tuned, is there anyone that can help.

Do you have the Focus Central 65mm throttle body? Those things are notorious for sticking.

unplug the idle air control motor and adjust the idle with the screw on the throttle body. if that fixes it then you will know it was your idle air control motor. it probably is... with a vacuum leak large enough to make it idle that high im sure it would be to lean to run at all. your problem is probably the iac

sorry i forgot to post that i have already replaced the IAC motor. Boosted2nr i dont have a aftermarket throttlebody. the more i think about it the more i think it is the TPS. It shoots up to 3000 when i take it out of gear, but when i start it up after turning it off, it goes back to normal. if it was a vacuum leak it would do it all the time. Right? i think im gonna replace the TPS and see what happens

check the BOV. Sometimes those leak vac and you have to adjust them to not leak when idling. Just a suggestion anyway.
