Any other owners of a 97–98 2.5L four-banger have any advice to share about the catalytic converter? I think the 97 and 98 2.5s had the same catalytic converter, and only had the one. Right?
- Around how many miles did yours begin to cause trouble?
- If replaced, did you go with an aftermarket or get a local shop to do it for you?
- If replaced, what else did you do at the same time?
- And of course, how much HP did you gain in the process? ;-)
