Well, fitted the new IAC to the Fiero and the problem still existed. So I pulled the throttle body off and noticed all the IAC passages were clogged up. Probably too many short runs?
Gave it a thorough clean with carb cleaner and got lots of bits out, and after resetting the IAC again it's much better.
