First tell me where you can get one cheap! I agree that it could also be the AMM...hope it is the IAC though. You can also try to clean your IAC without much dificulty. I have done this often with my two cars and got good results. To remove it, simply unplug the electrical connector, the two hoses and loosen the belt holding the strap around it. (also how you remove and replace btw) Take some carb cleaner and spray both holes well. I uses a little screw driver and push down the plate below the spring to loosen stuff up. Give the cleaner a little time to work...shake it up with your fingers plugging the holes. After you feel comfortable that it looks a little cleaner, reinstall. The car may sputter a bit if you did not get all the cleaner out but every time I did this, the idle returned to normal. Oh, and if you do this and the car runs like crap...much worse that before, save the hour I spent the last time I did this trying to figure out what the H is wrong and look at your vacuume hoses. I accidently pulled one loose! Good luck!
