Okay, new problem! P0430 then P04020 CELs
Hey guys!
Just so you don't get bored, I have a new issue!
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?
Thanks!
