Just found out that the OBD meter shows P0420 & P0430 on BOTH banks (# 1 & #2).. Does this mean I need to replace something? Like o2 sensor or catalytic converter itself? Please advice.. Thanks!!!

A) search/google is your friend

B) Bung extenders or if you WANT a tune, they can just deactivate those two O2 sensors

What he said.

You have CAI, HFC and CBE so it's time for a tune to correct your A/F ratio also get rid of the CEL. But that will avoid your factory warrantee so that's your call. Otherwise(which I would do) get the bung extenders for your o2 sensors(non fouler mod. search it) and hopefully that will fix it. It is also the cheapest solution. Or just put your stock cats back on and call it a day.

those codes will tell you what you should check and not necessarily changed...but if you really insist that something is wrong with the z don't press the DSC off or your Z will explode!

Don't fear the light son the dark side is coming to its end!

Friends, THANK YOU VERY MUCH for all ur inputs. This was my very first posting, I'm so sorry if I ever irritated some of u guys with my inquiries. Honestly, I've learned alot about engines (parts,mechanism,dynamics,etc..)bcoz of this problem that I have. Now I'll try first d o2 bung extenders, and if that fails, then I'll have it tune using uprev osiris.. Thanks again!
