Got a CEL scanned and I have a P0430 error code!
I'm at 63K right now and got my CEL scanned today and it is the P0430 code. I did a search and it seems to be failing catalytic converters. I talked to a Lexus tech at work and he said to replace my O2 sensor first. So how can I test if it's a bad O2 sensor or if it's a bad cat? I do have an intake, deleted secondary cats, and exhaust but never have I touched the cats.
