Throttle body porting issue....kind of. Well I recently ported my throttle body and everything came out nice.....except when I put the throttle blade back in and tightened it back down the blade would stick in the body when fully closed. So I went over everthing to figure out why this was happening...turns out one of the screws that hold the blade down was/got bent somehow so when you tighten it it offsets the blade in the houseing. I went to my local gm dealer to see if I could get a new screw, but they said no sir.....only throttle body. Anybody happen to know the size of this screw...or maybe even have an extra one lying around?
Just take the good one you have and make a trip to Lowes, Advanced Auto or Home Depot. They might have it. Keep in mind, it's almost certain to be metric. If you find the right size, but it's too long or something, you can always dremel it down a bit if need be.
