Hi all,
I have a 2000 GMC Safari with a 4.3 Votec engine out of warranty. The throttle sticks when at idle but operates smoothly when above idle. It gets worse as the engine heats up. I don't think it is the cable. I think it is in the throttle body bore. I have read of this being a problem on Chevy trucks. Some have the said the solution is to have the throttle body and bore cleaned. Others have said GM recommends replacing the throttle body which I expect will be expensive. And ideas out there? I would prefer to avoid spending the bucks required to get the dealer to replace the throttle body.
Thanks,
Marty
