I got a receipt when I bought my car of a new iac and I think it was in the mid $200's or 300's....Either way shop around, all the stealerships around me always give different prices, I dont know if theyre pocketing some of the money or what but sometimes there wayyyy off price of the other ones. Some of the evo shops might have them to for a better price and in stock. Check out extremepsi.com they have a bunch of oem parts for good prices and get to your house next day if your in NJ. You can try cleaning it or maybe has a bad o-ring but if you have a vacuum leak or bad tune or something it can also prob cause the issues your having. I know I wouldnt want to buy an expensive part if I knew I didn't have to.
Also if you have to change it it's prob easier to take off the throttle body since theyre small phillips screws, mine didnt come off easy anyway

nevertheless, I already confirmed it's toast following these steps:
Unfortunately the IAC always always always "looks" fine, (well unless it's just broken to pieces which I've never seen) however looking at it will not tell you if it's good but you're in luck because it is VERY easy to test the IAC.
1. Unscrew the 3 screws that hold it in and leave it connected to the electrical connector.
2. Have someone else (or you can do this yourself) turn the car to ON but don't crank it.
The little knob on the IAC should slide in and out as it looks for the correct place to dial in for your idle and it makes alot of clicking noises as it slides in and out. It is very easy to hear it. When my idle is off and I'm cruising and drop the clutch as the car almost dies if I listen I can hear the IAC moving to catch the idle. If it doesn't move at all, the IAC is dead. Also make sure to check for the o-ring gasket on the IAC. It is a very unique and specific size/thickness. You can't just find one to swap it in, I've looked and could never get one to fit other than the factory one. If you lost that o-ring that will cause idle issues also. If your IAC is good and the idle is still off check for that o-ring and remove it then lubricate it with some grease (assuming you have it). It's a pretty easy item to diagnosis thank goodness

My iac is jammed. If you take it out of the TB keep it plugged into the harness and turn on the ignition key without starting the engine. The plunger should move and the motor should vibrate to hold it's position. My valve didn't move or vibrate. It just started to get pretty hot since the motor is jammed. That's it really. Obviously there is a design flaw since it only lasted 55k miles.
