umm...for some reason i wanna say i had the same code thrown and everything was good underneath and with exhaust and everything like yours is...and i replaced the gas cap and it went away. i cant remember what code it threw...mightta been a PO440 someone correct me if im wrong. just a thought.

p0440 is an evap code i believe. and thats usually due to a loose/faulty gas cap but im getting an actual catalyst efficiency code.

damn your right. just jogged my memory when you said evap. as for your issue..i am of no more help. Best of luck.

yeah i really think im just going to throw a converter at it. if it doesnt fix the CEL then oh well its only 160 bucks

I have never had to replace a catalytic converter on any car I've owned. My 1995 Escort has over 202,000 miles on it and still has the original converter. The O2 sensors, now I've changed plenty of those.

it happens dont worry. if a cat gets coolant through it then it can get damaged. if it gets tempature shock, i can get damaged, too much fuel (missifre) for too long can damage it. you have just been lucky.
