..is grounded.
huh. i just went with the 'it's got 247k on it, it can't be good' method and replaced mine. when it was finally off the car i could look inside it and see the molten sludge that the broken catalyst had turned into; massive heat buildup due to blockage here and there; dunno what actually shattered the catalyst. but it was pretty cool looking. and stinky.
edit: some good news - if this is your issue, once you replace it you might find you have a lot more power than you did before. it was impressive to me the performance my car had with the new cat on. a hill in town that i'd normally have to downshift to 2nd and floor to climb i could pull in 3rd with hardly any gas at all.
