Hi Rob,

I've had the IAC out a few times. When I was replacing the intake manifold gasket, I sprayed the IAC with carb cleaner to clean it out. Though I didn't apply and lubrication after. It didn't seem to make a difference once I reinstalled it after cleaning. When running the injector/IAC diagnostic on the car, I can hear them operating. I'll see if I can find some of the CRC lube and apply it to the IAC.

I plan to take a road trip to the junk yard this weekend. I just chatted with a guy that works at this particular yard and he seems to be a 240 "enthusiast". They have a bunch of AMMs and IACs that match my part numbers in stock, so I can try those out. I may pick up a spare set of injectors depending on the price. That way I can ship mine off to get cleaned, assuming the used set doesn't improve anything.

Good to know about your experience with the idle, especially form someone who has owned 13! If the AMM, IAC, and injectors don't improve anything I'll chalk it up to "that's they way it's going to be".

Thanks for your input.
