I'll keep trying to back out the set screw, but I don't know that I have much further to go. Right now if I unplug the IAC it will idle for about 5 seconds before dying, which is better than before when it would die right away.

5-sec sounds decent. But you're backing the screw out? If you're backing it out you're closing the throttle plate...

I'm moving the screw out which happens to be the same direction the throttle moves when the accelerator is depressed.
