I just don't think the car is "moosing" is the widely accepted definition of the term.
The noise I was getting sounded like a belt squeaking, not a fog-horn like belch.
I just have a feeling that I'll get the car back, and it'll keep on squeaking away on cold starts, thereby having made the IAC valve replacement a cash grab.
BTW, aren't those supposed to control idle speed and quality? I've had no noticeable TH or bad idle - the car's been great in those respects.
Just the darned cold start squeaking that sounds like belts but I know isn't.
Otherwise, I just find it amazing that everything they've found wrong with the car is suspiciously not covered by my extended warranty...
