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 
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...?
