I have a 2000 tj with the 4.0, and lately its been studdering and jerking under a hard pull. I changed the #1 o2 sensor, which helped for about 2 weeks. But now its doing it again. Doesn't matter if its on the highway or city. If I lug the motor, it will fall on its face. And I have no codes either. Any ideas. Or suggestions?.......
