Quick Fix! P0420 & P0430 Codes on C7 Z06

[@djdragons7734]

Just got this code for my 2014 Toyota Corolla. I’m thinking of buying the cataclean hopefully the engine light won’t appear after. Can we get an update on whether this worked?

Yes, it worked for me - read the description and it explains my story a little bit! Should work, if you have the OBD II scanner you should clear it after and then if it pops back up later you might have something more serious. Maybe just a dirty/bad O2 sensor.
