throttle a little sticky - The 1947 - Present Chevrolet & GMC Truck Message Board Network

fortuneatly enough not while i'm driving. just when i'm at idle at a stop light or in traffic i have to put a little more force to get the peddal to unstick. so could it be bad throttle shaft bushings or just a gummed up throttle shaft? been thinking of porting the throttle body so this might just be the opportunity. but i would also replace the throttle body before attempting any kind of porting and polishing so that way if i make a fubar i won't be a$$ed out, just mildly inconvenienced.

I think there was a TSB out for this problem a while back if you have cable throttle. spray some lube on both ends of the cable, that should fix it

It's carbon buildup behind the throttle blade from the EGR. Pull the throttlebody off, clean it good, that should fix it right up.
