    Just threw a 420 code (keep it down stoners). Anyone have an idea where I should start? It's supposed to be an exhaust leak before the o2 on bank 1 but I can't find anything wrong.

    Run a bottle of seafoam through it it will clean your engine and you'll see where your exhaust leaks are

    Your only solution is to hot box it, this will ensure the cab is sealed properly :rasta:
