my idle rpms have been around 1500 and sometimes they will climb to almost 3k...if i unplugged my IAC it will idle at whatever i set my TB idle screw at. i replaced the IAC and it still is happening, unpluigged battery and even messed with my xcal2 and it still idles above 1500 what is the prob, and i cleaned the MAF

can the xcal monitor pids? im wonder where your (tps) throttle position sensor is reading. try unpluging it and see what happens.
