I have a 2000 chevy 1500 silverado 4.8L and I'm having issues with every once in a while when I start it up the engine will blubber and sometimes hesitate when pressing the gas pedal. Sometimes it will even stall. I already replaced the fuel pump, and that wasn't the cure.

I read an article the other day about this problem and it says that a faulty throttle position sensor can cause this very problem that is the only thing I have not changed on my truck I believe it is about $35 at autozone so that is my next step
