Hi Scotty, I have a 2006 Nissan frontier SE V6 4x4 regular cab and I have 2 codes throwing the check engine light. P0430 and P2A00 but I had the O2 sensor replaced (bank 1 sensor 1) that the second code indicates. I know I have and exhaust leak at the Y pipe and a small hole in the muffler, is there a possibility that the leaks are causing these codes? It has been suggested to me that i have one of the the catalytic converters replaced for the P0430. Are there any other options or any harm in waiting a while to have the cat replaced? I'd rather not pay for it if i don't have to right away.
