03 Silverado 1500HD 4x4 6.0 Im doing alittle maintence to my truck. I got the "Reduced engine power" warning a few weeks back and have been reading allot about the TPS being the problem. The fuel gauge sending unit stopped working a few months back and Im planning on changing the fuel pump also (127,000 miles). I wanted to find out a good replacement brand TPS but cant really find any. Any suggestions.

 

delco... or delphi... or whatever. the gm one lol

 

Yeah the ones they sell at the parts store hold up pretty well. Ive had my replacement on for 3 years no problems.
