After I fixed the problem from before my clutch/IMS job (loose #6 plug), I took the car for a 250 mile joyride in upstate NY, and it threw a P0430 (bank 2 cat below threshold). I cleared that and then a few days later it throws P0420 (bank 1 cat). So.... air leak? both cats going bad (unlikely)? any ideas before I start ripping into it?
