Where in western NC you at? I live in Raleigh and have family in Statesville i'll be visiting week after next (going on a cruise monday, stopping by on the way back for a few days). If you haven't got it by then we could get together and i could give you a hand. I love working on GP's.

Like Bill said though, check your vacuum lines and actuator. Don't just assume they're right or anything like that, go through the lines systematically.
