Thanks for the update. IAC makes sense. LOL I was going crazy trying to figure out what an IOC was.
When you had the IAC removed, did you closely inspect where it enters the throttle body, making sure there isn't dirt or corrosion that could prevent the IAC from moving properly? Also, why do you pump the gas? With fuel injection, that really shouldn't affect anything. If you are trying to clear a flooded engine, you can hold the throttle to the floor when cranking, which shuts down the injectors. But other than that, it really doesn't do anything.
What happens if you don't pump the throttle five times? Also, have you tried cleaning the throttle body?
Let me know.
