My truck has ben running sluggish, this morning I went out to start it, I put it in gear and when I did there was no acceleration? I could put the pedal to the floor and the truck wouldn't move, The SES came on, when I hooked up my scanner I had 4 fuel rail codes? Could this be injectors? If so didn't GM just extend there warranty on the injectors to 150,000 miles????
I changed the fuel filter just a few weeks ago, I had an issue with the truck starting one morning when it was super cold(down in the teens, the fuel was not treated), the fuel jelled up. When I took the filter off(early afternoon) the fuel was stilled jellied and it was in the 40's. I guess once it jells it stays that way? But yes the filter was only a few weeks old.
