    Help needed with high idle issue. When the car is started it revs to around 2000 rpm and then slowly drops to 1200 rpm in park,when its in drive it stays around 1100 rpm and runs rough. I have cleaned the throttle body,replaced iac and tps,checked for air leaks changed temperature sensor and tried the idle re-learn procedure and nothing is working. Any advice would be much appreciated as i'm loosing my mind lol.

    Tb butterfly can get sticky when old and not close properly. Try pushing the tb closed by hand while it's idleing.

    Have you played with the idle screw? That can cause it too.
