The throttle stop screw does just that, stop the throttle. It keeps the butterfly from slamming completely closed when you let off of the pedal. If it did'nt do that the car would die because the IAC could not react fast enough to set an idle. Just leave the screw where it is from the factory. my E-Brock T/B whistles under light accel. also, I've never figured it out though. Does'nt seem to make a difference in the way it runs, so I'll leave well enough alone.
