Primary O2 Sensor is only reading the pass. side. As long as the pass. side runs clean, no code. No real way to read both banks unless wiring harness is cut into. Screw all that.
WOO HOO!!! Va. has lifted the "No True Dual Exhaust/cats" law. We can now run true duals as long as we are running DUAL CATS.
I will be running DUAL cats. No cats in picture as I haven't gotten them yet. The REAR (Secondary) O2 sensor is only for Uncle Sam/Tree huggers.
(Only tells what the converter cleaned up, and has No ill effects on Air/Fuel ratio). Next to go is the Factory Muffin.
