This is the IAC right? I've seen this code pop up on a couple of normally idling legacys. Mine idle's fine, and will adjust the idle enough to drive the car with my foot off the gas in 4lo uphill, downhill ect. Why is it setting this code if the system is apparently working? The fuel cut kicks in if I floor the car off idle.

Give it a good clean - use carby cleaner and squirt it out, spart some WD40 on it then put back together

I'd do that if it were sticking or acting funny, but it's not. It's working perfecly, but throwing a code anyway.
