i have a 93 chevy cheyenne single cab and i swapped the  stock throttle body for a chevy 350's because of a transmission change.  Now the motor is idileing very high and i was wondering if there was something i missed and needed that i didnt take from the 350 or if the throttle body wont work

A lot of times, fast or slow idle speeds are caused by a vacuum leak or a hose not plugged in. I'd double check to make sure all your hoses and sensor harnesses are properly attached.
