I have the same issue with my 2014 6 cylinder silverado. I have changed the spark plugs, wires, coils, fuel injector and wiring harness. Still getting codes. Mechanic has no clue what problem can be. We are now trying to trace all wires involved to see if any are damaged.

If cylinder 6 is still misfiring after changing the spark plug, wiring, and coil, check the fuel injector, cylinder compression, and the wiring/connectors to that cylinder.
