The IAC is such a pain in the as to get to. It requires the removal of the intake manifold, so that is my absolute last resort.
Next weekend the cams get swapped out for the stockes and I try to part out as much as possible off the car. If all goes well I'll be in something else ASAP. This car is absolutely rediculous. Its only three years old and is such a pain in my ass/wallet. It was cursed since the 100th mile where it needed a transmission rebuild. I should have taken that as a sign this car would be trouble.
