My 2000 Jeep Grand Cherokee is having a rough idle and/or sputtering at times. Seems like it wants to stall, but hasn't. The check engine light is on sometimes. The computer reads O2 Sensors. Which have both been replaced but still having the problem. Sputtering occurs on acceleration. Any ideas? Thanks.

With the new sensors, does the computer still kick out the same code? Have you checked to catylatic converter to make sure it isn't getting plugged? When was the last tune up and have you checked fuel pressure?
