Would a faulty IAC valve make a 2000 Mitsubishi Galant stall at a low idle?

Yes, it would. While the Throttle plate is closed when not pressing on the gas pedal. The IAC is a bypass passage that allows air to continuous flow to the engine. I just had the same problem with my 2000 Mitsubishi Galant. I unplugged the IAC and the engine no longer wants to stall out, it just runs at a higher RPM to compensate for the nipple on the IAC not moving back to create the bypass passage.
