Bad Cat

Hey back again, I took some time getting back after the site collapsed last year.

Well here is an interesting story. I had the Check Engine" light coming on for a a couple of times a week last year. It would go out after three or four re-starts. Then one day on the freeay the car just died!

Whenthe dealer looked at it he said that the O2 sensor was bad, so they replaced that. Then about three months later, about a month ago, the engine light started coming on again. So into the dealer (different dealer this time) it whent and he said that it not only was the O2 sensor bad but that the catalytic converter was not performing up to specs and had to be replaced. So I had to wait a week while someone swam over a new cat from Japan.

Has this happend to anyone else? A bad cat? Granted the bad O2 sensor would most likley lessen the life expectancy of a cat. I mean what causes TWO O2 sensors to go bad????
