I'm curious as to how long most catalytic converters last? I've never had one fail on any car I've ever owned, but my ex wife's 2000 Civic needs a new one and it's got only 122k on it. That seems kinda early for replacement to me. What would cause a converter to fail so early? I always kept up the maintenance on that car, and we've always run fuel from the major gas stations here (usually Shell or Esso)
