2007 350z O2 sensor problem...
Hey I recently put Berk High Flow cats on my 07 350z. Every since, my CEL light comes on. Car is running real rich due to the codes from ECU (P0420,P0430). They are bank 1 and bank 2 sensors right after the cats. Any suggestions on how to fix this problem would be greatly appreciated, considering inspection is due this month....Thanks
