What exactly is the IAC supposed to be doing?
Is that similar to the Idle control that was to up the idle when the A/C was on, back in the carburetor days?

Always curious about how things work.

Idle Air Control - it's a computer controlled (sometimes poorly) air leak into the intake that a race car doesn't normally need.
