1999 Wrangler SE 2.5L engine problem

My 2.5L engine (175,000 miles) had the o2 sensor just below the manifold went (check engine light came on and I had the code checked and confirmed it was the o2 sensor) bad the other weekend. I replaced, and after a week, the new one went bad. When I removed it, it had a lot of black soot on it. I checked the spark plugs and they had some soot on them too. Any idea what the cause is and how to fix it?

Thanks!!!

Junk for TJ's. Go and get a NTK/NGK brand and stick it in. I did that for my past 97 2.5 and it worked great.

Therein lies your problem. While Bosch makes a superior product IMO, our Jeeps don't like them. As stated above get yourself a NTK brand sensor and your problems will go away.
