Bad oxygen sensor or something else?please help?

i have a 98 jeep grand cherokee laredo. my engine is a v6 4 liter. i got a code that said my oxygen sensor was bad bank one sensor two. it said the voltage was too high for operating conditions. i havent changed it yet i also had a bad camshaft pos. sensor and after i changed that my check engine light went off. it seemed like it was running ok after changing the cam pos sensor. but today when i was driving it i was going 55mph and it felt like my engine was getting ready to cut off and it kind of bucked and jerked while i was driving it and it ran rough. it did it for about a min and then stopped and went back to normal. i was wondering if it was something more serious than the o2 sensor.

If it did that while driving, then your Check Engine light should have come back on. If it is, the best thing to do would be to scan it. Other than that, it sounds like it could be a clogged Catalytic Converter. Sometimes something gets knocked loose inside and clogs it up. But scan the ECM first if the light is on.

I would have it diagnostic checked. Autozone will check it for you for free and give you a print out of the specific parts you will need for the repair. Most mechanic shops charge $50~$75 bucks to do the same thing. I wouldn't advise changing parts to try to chase down the problem as that can get very expensive very quickly. The guys at Autozone will help you out.
