A faulty IAC will cause stalling problems at idle. Most of the time if you hold the gas pedal down it will run fine. Be careful because these symptoms can come from an EGR valve that is stuck open aswell. If you have a fast idle i would look for a intake leak.

No! it only controls the air/fuel mixture at idle - it is by-passed when the engine revs-up. Generally, when there is a problem with the air control valve it causes the idle to become erratic and 'hunt' and maybe the engine keeps stalling.
