I Need Help With My 1997 Jeep?

I have a 1997 jeep wrangler with the 4cyl anyway It keeps burning o2 sensors up ill replace it with a (denso) a good sensor and it will last maybe 1 month than it’s back to burning rich, black smoke out of the exhaust will hardly idle. It does not use oil or antifreeze I’m lost on this one

    Perhaps you should try an NTK sensor. NTK are the OEM supplier for Jeep. They are cheap at http:www.rockauto.com and more so with 5% off. Use the code: 28062E85EA17
