Channel: Project Dan H
Date: 2020-11-01

I have frequent questions about Jeep 4.0s rrunning roughly even though many ignition components have been replaced.  I recently experienced this in the General Grievous ZJ and now I can confidently report that this problem can be caused by a bad upstream O2 sensor.  Hope you guys enjoy!
