Try to reposition the AMS and tighten the clamp that holds it. I cleaned the throttle plate once and was not able to put the AMS to the exact position I took it off. It shot codes and the ASR light came on. After repositioning and tightening, the codes cleared and the idling stabalized @ 500(+/-10) with transmission engaged and a/c on . Try this and hope it helps
