Well, my idle speed control motor went, which causes the thumping noise when you shut the car off and makes the gas pedal pulse. Also, if not fixed the isp motor can cause your tranny to go in limp mode after a while. Ya not cool.
Love the car; very quick and peppy for a big car, smooth ride. Just got back from a 1000 mile round trip. The car didn't over heat, stall, or break down at all. Also I was getting about 25 mpg on the highway. I think that's pretty awesome for a V8.
