1997 XJ, 4.0, stock engine, etc. Had some issues with the exhaust over the past couple of weeks, ended up replacing the down pipe and catalytic converter, and two oxygen sensors. Last week I ran it without the rear O2 sensor in place, got a check engine light after about 100 miles. Finished installing the new cat and O2 sensors today, backed it out of the garage, CEL is still on.
Does this take a few miles to clear or do I have another fault? I figured I'd start out by fixing what I knew was broken.
I had a stumbling issue at high rpm's last night while accellerating on the highway, trans kicked down, revs went to 4000, engine stumbled, trans kicked up a gear in response. I thought I was going to stall out when it stumbled, I was half way through an "aggressive lane change" and had to abort. This is after running 500 miles or so without the downstream O2 sensor. Related? I recreated the stumbling later on the highway, couldn't get it to do it by revving unloaded (parked) after doing the O2 sensor.
Thoughts?
Thanks,
Mark
