Not sure this model/year has an IAC, does it? If it does, he may be calling it the "Cold Idle Speed Actuator" in the video above?
I did have an IAC on my '03 UC. Gave me fits trying to clean it out with carb spray. I would do it and then a couple of months later I would get the same symptoms again. Did that for about a year until I finally just replaced the IAC and that was that!!
Cheers,
