Look here: https://parts.subaru.com/a/Subaru_2005_ … 50-08.html

Probably 22650AA182, $353. They are pretty easy to clean and do get nasty, what's wrong with yours?

Re: OEM Idle Air Control Valve IACV IAC

Thanks , I have the crazy idling when hot issue. When the outside temps get above 65-70 degrees and I have driven he car 30-40 mins stop and go traffic the idle creeps up to 1.5K then 2K then yesterday it was 90 degree outside and it went up to 3.5K. Cold start at the same outside temp and it idles like it should around 500-700 rpm. Second spring/summer it has done it. I already loosened the cruise control cable and cleaned the IACV no improvement so I figure it's time..... Certainly open to any other ideas.

Bummer, I had this issue and it was the cruise or throttle cable, both were a bit too tight and it would rev while idling in heat. How well did you clean it? I pulled mine off the car and really went at it, was much dirtier than I expected. Not sure if it helped anything.

Re: OEM Idle Air Control Valve IACV IAC

Drove it again today (same route every time) and it was 72 degree outside and it only crept up to 1500-1800 vs 3500 on the 85 degree day. So either the fixes worked a little or it was the cooler temp. In the meantime I just ordered a reman IACV on ebay for $25. figured i cant go wrong. If it works great, if not just put the old one back on. How far out did you loosen the cable all the way because mine now has some slack in it so I cant imagine it tightens up that much from the heat.

Re: OEM Idle Air Control Valve IACV IAC

The issue is almost certainly the cruise control cable is too tight. Loosen that cable a bit (at the bracket by the throttle body).
Its because the cruise actuator is right next to the turbo and that area just gets hot, and then on a hot day especially if you are in traffic (slow moving, stop and go) it gets REAL hot down there.
This causes the actuator to unintentionally tighten the cable.
If you dont have a heat shield on your turbo, get one!

Regarding the IACV, you could just get an 02-05 WRX throttle body (with the IACV on it). I probably have some lying around.
However, almost guaranteed that isnt the issue. the IACV is electronic and would not be affected like that

Having said that, if you pull off the IACV, replace the gasket! its a special one you have to get from the dealership
