Just talked to Toyota. Apparently on the 2003-2005 GT-S, the IACV is integral to the throttle body and cannot be bought separately. For 2000-2002, the IACV can be bought alone. So I guess my questions are:
Has anyone ever removed the IACV from their TB, or know if its possible?
Any chance the 2000-2002 IACV will actually work?
What's the likelihood I could fix my IACV? Is there a common failure mode?
