multi mis fire problem
I have an 05 silverado 2500hd 4wd 6.0 auto. I get a code of a multi misfire in 7+8. What I have done: switched around to other cylinders, wires, plugs, coil packs, and injectors, discounected battery over night. Still showing the same codes. It seeems to level out after 2k rpms. fuel pressure good, no vacume leaks. Been adviced to do a computer upgrade.
