HELP PLEASE: Engine Idle Problem

Below are some pics I just took from my car. If you get that part installed properly and it still gives you problems, the next most likely suspect would be the UD pulley. Keep an eye on your voltage gauge to see if it fluctuates wildly with turning on the AC.

Might come in handy.
