Question about 2005 Chevrolet Silverado
05 Chevy V8, 5.3L, 4wd, engine missing between 48 and 60 regardless of load. Just started it. Engine starts and idles fine. Runs ok at low speeds. No check engine light. Poor gas mileage. 14 in town and 17 on road, was about 17 in town and 20 on road. 85000 on engine, mostly road miles.
Based on what you say here i suspect maybe theres an open in the tps. you can test it with an ohmeter if you have one. some scanners will even show what its doing.

I disagree with changing the MAF sensor. I had the same problem for about 4 years until today on my 2000 s10 4.3 4wd 125K. It runs like new, and all i did was paid 6 bucks for a can of mass air flow sensor cleaner from auto zone. Try this!! it was awesome the results
