Having a weird idle problem too, the car will idle low and dip down under 500rpms when coasting in neutral. Then when I come to a complete stop the car will idle up to 900-1000rpms like it should. It affects my brakes and PS which is annoying, anyone have any suggestions? Gonna check the iacv tomorrow.
