Along with the vacuume leaks I would check the carb. The accelerator pump might be out of adjustment or something else in the carb. Currently I have the same problem with mine and I just adjusted it and for 1 day so far it's ran fine but I have a holley on mine. Carb may be dirty also.

If theres a sensation of bucking this is a transmission selonoid 15 to 30 part only automatics has this
now if theres trouble accelerating theres a couple things to look at
fuel filter fuel pump sending unit
clog in fuel injectors or vacume leaks start with break booster most of time this would be it

Where is the throttle pedal sensor located on a 2002 cheverolet silverado


There is a throttle valve positioner sensor located at the end of the throttle valve shaft on the right hand end of the shaft, the sensor then bolts to the throttle body as you face the engine from the front. A defective sensor will set the check engine light and give hesitation during acceleration.
