At least at this point it's isolated to cyl #6. Have you checked the injector? connections? I know you stated that you replaced a lot of the ignition system, but have you verified spark on #6?

I would think there would be a lot more codes if it jumped time. Have you performed a compression test?

Since your misfire went away in 2,,4cyl. But stayed in 6,I'd recheck my plug ,could be a gap or dirt in between electrode
