You'll need to remove the TB and clean off the carbon. That could be all there is causing the problem.

The best way is to remove the TB though, since none of the gunk you're removing will enter the plenum and perhaps effect the spark plugs and/or 02 sensor down-stream.
At the same time the TB is off, it's a good idea to remove the IAC and clean it too. If the butterflies and carboned, you can bet the IAC is too.

thanx for your help but what i mean my reset is that there is a button in the t/b of the C-4 vettes that resets the tv cable and you reset it by taking the throttle wide open while the car is off and there is a metal button either in the middle of the throttle lever or beside it. but when he reset it the throttle didn't stick anymore but the car runs like crap

Oh Oh!!! What you are describing is NOT the proper way to adjust the TV cable. First, the TV cable adjustment does not affect how the engine runs. Second, if the TV cable isn't adjusted correctly, the transmission can fail, QUICKLY. Your service manual has the adjustment procedure. If you don't have a manual, after you go HERE and order one, do a search. It has been explained many times, on here.

didn't think it could hurt anything because that is what GM told us to do. didn't find the procedure in the owners manual or any of the big manuals that supposidly have everything about 84-96 corvettes

BTW, a service manual is different than an owners manual. I gave you a link for the "Factory Service Manual" in my last post...if you care.
