The wrench for the EGR tube is 1 1/16". Don't bother removing the IAC, as removing the IAC is probably just as hard as removing the EGR valve with the IAC in the way.
Edit - Oh yeah, also, it turns a way that seemed backwards to me the first time I did it for some reason. Basically, if you're wrenching on it from the driver's side, you want to take the wrench and crank down on it to loosen.
