Trouble codes need Help
check engine light came today and I have two codes po420 and po430 I know it is a Catalyst system efficiency banks 1 & 2. I have JBA high flow cats they were but on car a year and a half ago so why how?????
As Super T told me, these codes from the 02's can be thrown whenever it pleases and where ever. Some people have gone years without throwing codes and some got it a mile after ( i got mine 20 miles later ) the Predator can do the trick
So should I just clear the codes?
yes and use predator to disable the rear o2 sensors so they wont pop up again
