well im not really familiar with your specific engine, but there may be a stepper motor on the throttle body with some passages that allow air to bypass the throttle plate when its closed. however holding the gas pedal down would bypass the IAC, so if it still dies when you hold the gas pedal then its probably not the IAC, more likely a problem with a sensor that the PCM uses to figure out how much fuel you need to start the car.
