2002 GMC Sierra 3500 2WD Crew Cab Dually 232,000 and climbing!!!! Injectors replaced twice, 1st at around 140k and last at 190k, Turbo replace and injection pump also replaced around 200k. No blow by either!!! 6 new tires, fresh oil, and just bought a Bully Dog Power Pup. Also got a Bully Dog Shift Kit that I am going to install pretty quick so I can change all the fliud and filters in the tranny. Having a hard time with one problem though, my milage stinks. I am getting around 12-13mpg on the highway, and 10mpg around town. Hard to start, but if I put a brand new fuel filter on it has no problem, but one tank of fuel and back to hard starting again. Please anyone with any suggestions PLEASE write to me at ImSweetDaddy@aol.com Thanks For Reading!!!! Eric Muenzler
