Installing IAC valves and performing the Idle Relearn procedure on a GM Crossfire engine C4 Corvette

I'm rebuilding a Crossfire intake/throttle bodys that I originally bought to port the intake ports but decided not to, so now I'm just rebuilding them and I will sell the whole set up when I'm done. I used parts out of my car because they're pretty new and I know they work. Sometimes when building things with brand new untested parts you find a problem and I know these works so when I sell the system will perform as designed.
