    2015 GMC Sierra slt all terrain w/ 6.2. Engine was running fine then service engine started flashing and traction dash light came on. Engine started misfiring on cylinder 6 swapped coil with cylinder 4 computer still says 6 misfire. I replaced all injectors and spark plug with wire and started engine with same results…I’m going to do a compression test on it tomorrow but is there anything else I could be missing? Thanks

    So I replaced all injectors and fuel rails with wires . I started truck to find same exact issue- service engine flashing and engine is misfiring cylinder 6. I replaced cylinder 6 plug and it continues to misfire. The engine is quite other than the misfire and shaking? I’m going to get a compression tester to test that cylinder tomorrow. Hopefully it is good.

    Just wondering if you found out what the issue was? I have a 2015 gmc 6.2 today my truck did the same exact thing. Computer says cylinder 6 misfire? Dealer mechanic said possible bad injector
