Are you getting a misfire on the same cylinder after you swapped plugs?
You checked the gap on the plugs before installing, correct?
Pull the offending plug and inspect for any damage like a crack in the insulation and proper gap. If it looks fine, swap with another cylinder and see if it follows.
If it follows, it’s likely a bum plug.

As Wade said- check the #2 plug. At least it's an easy access. What plugs and from where did you get them? Still have the boxes?

Gap was wrong and plug was tighten down to much. Took the plug out readjusted it and tightened it correctly. Code disappeared, truck runs fine!
