any one know if i can replace the bushings on the throttle body, the ones that the shaft runs through, theyre shot, creating a vac. leak, code 34, and an annoying clicking noise past 1/4 throttle, LOTS OF PLAY, i hope i dont need a new TB! im broke as it is between my new heads and bumper...

 

Not sure about the one on our v6's... but my dad had an '87 Oldsmobile with a 2.8 in it, and the gas pedal got really hard to press- and sometimes it stuck! Our mechanic pressed a new bushing in, but it didn't last too long- solution was for me to get another one from a junked car and put that on his car.

Thanks for the info though; didn't know a bad bushing could cause a vacuum leak!
