I'm getting closer to betting my money on a bad/clogged/?? bank 2 catalytic converter because cylinders 2,4,6, and 8 are the only ones with the substantial misfires and now the common denominator is the exhaust.

Um, I don't think so, but I may be wrong. On a bad catalytic converter I think you just get a efficiency code or something like that. Remember, the cats are for emissions. The downstream O2s are to measure that the cats are "working" and doing the chemical reaction magic. Some guys get rid of cats and remove downstream O2s because of this.I'm getting closer to betting my money on a bad/clogged/?? bank 2 catalytic converter.
Looks like #4 is the winner... what's that plug look like? Compression reading? Leak down test? Maybe try swapping the knock sensor from left to right as well. If all of a sudden you get the knock moving over to the other bank when you change sensors... you have a bad knock sensor.Son of a buck!
