I measured pins 2-3 and they show 12.0V, also all of the fuses look okay. The throttle rests against the idle stop at idle, and there is slight slack in the cable, also it rests against the stop at WOT just fine and moves smoothly. If it was a TPS problem, wouldn't that set a separate code than P0100? I also took apart the intake tract and made sure it was clean and seated correctly, then reassembled it and sprayed WD-40 on the intake system and other places where a vacuum leak might occur and it didn't change the idle or the way it runs. Is it possible that a faulty CPS could cause this?
