Car idle jumps up and down until put in gear and drove and once parked after a few seconds it begins to jump up and down again between 750 and 2000 rpm's. Not sure if it is a IACV or TPS or the throttle body itself. But runs and drives fine but jumps around when in park and seems to use more fuel than it should.
