P0430 help!! Won't go away!
 

So I have a 2002 ss with 37,000 miles, I had long tubes and high flow cats, I always threw the p0430 code didn't mind it much, now came the time for lovely ca emission, so I went back to stock headers and cats, also have all 4 new o2s less then 500 miles ago. Now I have had to clear the same p0430 code so many times it comes back on and can't get it to pass smog, seriously going insane :bang: anyone help please! Thanks

P0430 means your bank 2 cat is not working...

i.e. the rear NBO2 response is too quick wrt the front NBO2.

Does your scantool have the ability to log the pids HO2S11, HO2S12, HO2S21, HO2S22...?
