Ill be keeping track over the long run but due to this I will have to start my O2 sensor experiment over so I dont have altered results

I gutted the #2 cat on my insight for the same reason. My number 2 o2 sensor was throwing codes. I took a spark plug anti-fouler and installed the o2 sensor into that, the installed it into the cat and presto! No more codes.
