ok so my check engine light is coming on and off at different times. As per Glider I checked the code and the answer is rear O2 sensor failure. The thunderheader exhaust has o2 sensors but neither are hooked up. I assumed with the PCIII that they were eliminated. So i ordered a replacement 02 sensor eliminator plug. I can not for the life of me figure out where to plug it into it. Any help?
