  I actually prefer the GMC interior. Gives off mid-century modern vibes.

  I never understood the hate for the column shifter. The console shifter just gets in the way, takes up prime cargo space and in my wife's Jeep, the dog constantly bumps the console shifter into neutral! Best choice ever to just make it a column shifter across the lineup and be done with it. (Bonus: Makes swapping from a 5 seater to a six seater far easier)

  I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

  Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles. I checked the oil today at 4800 miles since last oil change and barely reading on the stick. I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice. Towed a light 4000 pound trailer last week and averaged 14 mpg. I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
