I could have guessed that a likely cause is O2 sensor malfunction or cat failure, that link was next to useless.
My ride was throwin' that same code for almost a year on and off. I was past my warranty so the dealer wouldn't replace the CAT---blah...blah...something like $1000 plus labor to fix itThe answer is I want to get a new exhaust. :laughing:
If my cat is dead I have an excuse to get a JRRH, high flow cat, and something else catback. ray:
