Chevy 6.6 Gas engine
2021 Chevy 2500 6.6 GAS engine. Dead misfire on cylinder 6. Swapped Coils, plugs, wires, fuel injector, checked compression, running compression, valve springs are fine etc. All the normal issues. No ticking just a constant misfire on cylinder 6. I have spark, I have injector pulse??? I’m at a loss. Anyone seen anything stupid like this? Thanks if anyone has anything.
