[QUOTE="xackley, post: 425227, member: 17509"] If it had an exhaust leak before the catalytics, it might be clogged. You might want to gamble on a bottle of Cataclean, snake oil first, before even more expensive parts replacement. My dodge truck started throwing scary codes when I fixed a leak in my exhaust. I did use Cataclean, but do not know if the problems took care of itself or if the snake oil worked. My theory was the converter would never have gotten up to temp when the exhaust was leaking, the engine was running rich because the sensors were getting bad data, causing buildup in the converter. I did buy a set of spacers like this but so far haven't needed to install.
