Need Help *VIDEO*
Okay so a week ago i put up a thread about some problems ive been having and no replies. Maybe this will help. After running my truck and letting it warm up and then shutting it off and parking it for 30 min to 2hrs, when i get back in and drive i will start it up and start driving and before it can get to 2000 rpms it the truck loses power and the tach drops. It sounds like its missing and poping. Then i'll let off and it will be fine the rest of the way. I have no clue what it could be. Cat? Fuel problems??? Here is a vid of my truck doing it.

Throttle Position Sensor.... the behavior is (for the most part) consistent with one that is going out. Why it only does it in that fashion though...... that is a very good question. But, if exercising the gas pedal a couple times 'cures' it.....
Try this: Next time you think you are going to have the problem, pump the gas twice right quick, and see if that 'fixes' it. Or, just replace the TPS, and see if the problem goes away.......

tps = throttle position sensor..also check your map sensor on throttle body and the idle air control on the throttle body..check those out first..if you can get your hands on a fuel pressure tester you could check fuel pressure...but sounds to me like its in a sensor...
You can test the TPS with a multimeter. The Haynes manual has the procedure for it. If you don't have a Haynes manual then I guess I could tell ya.
