Funky Cars > Cherokee Problems Still

http://jeepinxj.no-ip.org/wordpress [Mike’s Blog] About a year ago, while wheeling at Paragon Adventure Park, I bent up my exhaust pretty good, had my check engine light come on and stay on, and randomly have an extremely rough idle complete with a surging after almost stalling. Now since I got back I checked the engine codes to see what was causing the check engine light. It claimed that my O2 sensors were bad.

For example, the oxygen sensor (O2 sensor) usually starts to fail from 60,000-90,000 miles. When it does, the check engine light will come on and a code 21 will be set.

GBMINI (MINI Cooper) weblog: Service Engine Soon (again!): From what I've heard, MINI engineers are looking into the problem. It doesn't seem that there's anything actually going wrong with the engine except for throwing the check engine light. That's probably not too much comfort but this is not an isolated problem.

Diffuse Shadows: File this one under mostly for my own reference, but here's a bit ofbackground in case you're interested: I have, as I blogged aboutearlier, installed an after-market header on my car. This headereliminates the stock manifold, which includes a close-coupled catalyticconverter. This isn't a big problem, as the system still has theprimary cat in the exhaust system, but it does post a minor annoyance inthat, as an OBD-IIcar, I have two oxygen sensors -- one before the pre-cat, and one afterit.
