Hello!
I would consider having a "smoke test" performed to check for vacuum leaks. You could also check the spark plugs to see if any any individual cylinders or a whole bank is running improperly. If all of the spark plugs look good and there are no vacuum leaks, then I would suspect the banks 2 catalytic converter is failing.
