Put in come cataclean in the tank and drove it for about 20 mins and the catalyst passes without a code. Previously, po420 and po430 was in pending status, now only po430 is pending.

Catalcean smelled like rubbing alcohol. Didn’t think it would work but I guess it cleaned the cats and/or 02 sensors.
