Throttle Positioning Sensor TPS

[YUOnDaGround]

I am just going to put this out there and if it has already been stated, then so be it.

My problem was that my Tahoe just didn't have a lot of pep in her step under about half throttle. After running cans of Sea Foam through the tank and the upper intake I still didn't get the response I wanted. So I replaced the TPS on the side of the throttle body and it made a HUGE difference. I notice that I am not depressing the gas pedal nearly as far to get going and there is a much faster response. Still have to wait till the next fill up to notice any MPG increases.

did you have like a bogging down sound in the engine and when you gave it gas it at 1/2 throttle it didnt do anything untill you floored it? cause mine is doing that right now.

well ill be damned. stopped by the parts place on the way home and bought a tps and put it on and it fixed my bogging, sluggish feeling. now i need to do plugs and wires and ill be set.
