We dont have a pulsing test light available at this time. Is there any other way to check the IAC valve?
Tested the IAC and it pulsed. While it was unplugged the engine started running rough and finally died. It wasnt as rough as when its plugged in, but it did idle rough for about 15 - 20 seconds before it died. Does this still point to the IAC.

Yes, I would try another IAC. At this point it seems to be the problem.
