99 Silverado accelerator sticking

The gas pedal on my '99 Silverado sticks when applying pressure from a stop or when on the hi-way. Any pointers before I start lubing from the pedal on thru to the engine? Any replies would be appreciated before I screw up my rear linkage.

Clean the throttle body.
Use a choke and carb cleaner and a old toothbrush and clean the deposits off the throttle blade and bore.
That should solve your problem.

Thanks Merlin. The Net is so cool when people put it to good use!

I'm a bit late with this replay, but I had the same problem. I asked my dealer about it reoccuring and opted for a more permanent fix. They plugged the hole in the butterfly throttle and adjusted it to keep it open a crack when idling. This way it doesn't have a chance to close fully and get stuck. They had to replace a module as part of this fix, but the total cost was only $85. It's worth it to me not have to clean it out every 3k miles.
