About the butterfly wearing grooves in the throttle body... perhaps once the bushings develop some play they allow the plate to scrape against the sides. Then there's always carbon deposits that reduce clearances and can also cause some rubbing. Just a thought.

Mark; I see what you are saying, I just do not understand why. The butterfly are almost identical are they not? The throttle body's should never close all the way anyway,if the idle stop is set correctly. Why would it wear grooves in the side?
