After installing my z1 test pipes I get p2096 and p2098 after a few drive cycles after clearing it continuously. The O2 sensor extensions are supposed to prevent this, but that's a topic for a different thread.
I thought that the secondary O2 sensors were only there to monitor your catalytic converter efficiency, and to alert you of problems with your cat. I don't believe that it figures into AFR calculation. What's the point of checking MAFs and TBs for post-cat DTCs? Please explain to me why I'm an idiot
