Assuming it was a faulty O2 I replaced both rear O2 sensors. Drove about 15 miles and P0136 came back. Thoughts? The two codes have been set for a couple weeks. Any chance the ECU needs to relearn having a operational O2 sensor. And for those that missed my last thread about this I am also running the URD O2 sim.
