Can you post the actual codes? I've had P0300 a couple times at WOT and just deleted it, air system bank 2 might be P1416?

OK, one time I threw P0300 was with the car in park, and someone reving the engine just to see how loud it was. But your dealer is right, could be alot of things...plugs...wires... As for P1416 that's most likely just a bad/clogged passenger side air check valve. Easy to replace yourself (PN 12565503) it's the black round valve between the metal air tube coming off the header that connects to the rubber air hose.

Your blue smoke means oil. Oil will very often cause misfires (not to mention rampant knock retard). If the oil consumption is new and there was no 'mishap' coinciding with it, then I'd suspect your PCV valve.

As for the check valve problem? I've no clue. Take it off and look it over. If cleaning it seems feasible do so. Otherwise buy new.
