    Same thing happened to me about six weeks ago. Definitely happens. Power went to crap. It was fully restored after replacing the cats.

    Same crap everyone else got
    did this on an xterra and a honda accord. Both still passing emissions. Neither's cats were clogged, they were actually reading as if they were gutted almost so now I just think of them as hi flow cats.
