All hail the gear shredder!
My IAC shit the bed today so I have a wandering idle from 1200-1900RPM. I cleaned it and put it back on with the same symptoms. Looks like I get to have my first warranty work done. The IAC is the thingy that controls your idle that is on top of the throttle body. It will cost Subaru $330 for the part + labor. Hurray for problems that can't possibly be related to mods. It took Danny and I precisely 13 seconds to diagnose the problem at Perry Subaru.
