Recently Cleaned the IACV and had to do ALOT of fiddling to get it back to normal. AFTER that saga, I went through my FSM pdf's and found that there is an actual service procedure for the 2.5 that does NOT require removal. :banghead: Oh well, lucky YOU. :brow:

EDIT:

I should also mention that the full service procedure for the 2.2's are included as well.

I would use Sea Foam as the agent. :banana:

PS. It's on the right side, midway down on the third page. Enjoy.

Awesome timing, I was hoping to remove and clean my IAC this weekend. I'll definitely try this first!

I just used this method. Kinda tricky, but I used my left hand to open the throttle, and my right to pull the hose up and situate it on the intake hose. Switched hands on the throttle, and poured the Sea Foam in straight out of the bottle. Tried a small bowl first... Not happening.

Easy fixes are the best. Now I have to wait for a new IACV gasket to come in at John Elway then re-re-re-do the IACV. Should be in this afternoon. I can't believe that the IACV bolts only take 4-5 ft/lbs of torque :-\.

Procedure for the 2.2's only seems to be removal/replacement. Is there an actual cleaning procedure? Looks like a fine CD; is that available from Subaru? I'm looking for one for my '91 Legacy and '97 Impreza.

They did the same thing as the 2.5 procedure on my 2.2 worked like a champ, that was about 15k miles ago.

The procedure for original style, solenoid (not stepping motor) IAC valves is simply to disconnect the bypass hose from intake duct and pour the cleaner in it with engine running.
