What in God's name is a Jobber universal o2? Does Jobber make o2 sensors or are they a business that sells them?
If there's a problem with the o2 sensor and/or converter the ECM would throw a 67 error code. What brand is the converter you're running? If you were running an OBDII compliant car-sound converter with a good/known o2 sensor, I doubt you would be having this problem.
