I think my IAC choked on throttle cleaner. As of late, it hasn't been acting right. I've had stalls, idles around 3000 RPM, and other oddities matching the million IAC threads in here.

As usual, RockAuto has the best prices. Anyone with purchasing experience know if the O-ring is included with most of them?

It should be included. But you can also check at autozone, I believe they have a box of O rings there.

Should be included. I've never found cleaning one to cause it harm. Maybe something bound up beind it though. I think it was pretty dirty.

The throttle body was a bit caked, but I'd cleaned the IAC before. Maybe I shot the pintle off one too many times. At $18 on RockAuto and a one-minute installation, I've got bigger things to lose sleep over.
