Thought I would post what I failed to see to correct my random misfire.
I thought I had checked everything listed to correct P0300. It came down to a small crack in one of the ignition coils. Felt really dumb not seeing the crack and not checking the OHM test of each coil. I only used a ignition spark light tester and thought all the coils were good.
Maybe this will help others.

Thanks for posting your experience in this matter.

Always a good place to start with misfires or chugging/sputtering issues: check over the whole ignition system.

I think someone should post a picture on where the ignition coil is located....yanno. Just for reference

Coils are on the lower left. It also shows which coils are associated with what cylinder. Another view of the coils, to the right of the supercharger serpentine belt, and above the dipstick.
