[PANAVIA]

Dont forget IACs are meant for many things.

1. Cold start up (increase AIR to rise idle point to warm an engine)
2. prevent stalling (snapping throttle shut, and the IAC will let it down from 1500 to 900 nice and easy.)
3. maintain idle set by computer based on timing advance, temp and such.

Example : car running *hot* at idle advances timing runs cooler kicks up the RPM (via IAC) to get coolant flowing.
