Well i changed out the Iacv and the car doesn't just rev up and down now but it still revs higher then normal by around 1000 rpm. Is there any way that the new ecu and my old tps just aren't reading each other like my old ecu. not sure that makes sense. Well what part should i check now, the car never had any problems before the ecu went out so i just don't understand how the TPS or the IAcv has went bad over night.
