    How many miles on the car? Could be that the cat has gone bad. Not likely, but a friend of mine with a 98 Accord had it happen to her, with only 80,000 miles on it.

    its probably not that its gone bad (unless its wired wrong/shorting out) its more so probably that your motor is running too lean or too rich
