my car had one already on when i bought it. no problems. i read in one of my mustang books they are good if you have a different cam than stock. the guy before me had ford put a e303 cam in it and they put it on at same time.

well I cleaned it with carb cleaner and then I tried that thing that adder said by taking the IAC plug out and try and it came down right away. It wouldn't keep a idle at all so I know it has to be working right? I have checked vacuum lines but I couldn't find anything.
