Chevrolet Repair: Sticking gas pedal, siverado, tps sensor

Question
I have a 2001 Siverado 25000HD with a 6 liter engine.  After it heats up, the gas pedal sticks and is hard to push down.  Can you tell me where to look for the problem?

Answer
Hi Eddie... could be a couple differant problems ...check the cable and make sure that it is not frayed or binding...check the throttle plate clean with a good air intake cleaner, check the TPS sensor and make sure it is not binding....most likely it is carbon build up in the intake and air intake cleaner should clear that up... hope this helps
