The O2 sensors sometimes fail in a way where they swing back and forth faster than normal. (about 2x faster)
However when mine did this it caused a rich condition and hi HC only.
Do they put the sensor in both exhaust pipes?
If your lean and getting hi NX then you should see some sort of asymmetry on L or R with Block/Integrator values.
One trick I have heard of is unplugging the battery just before going in.
When in learn mode the car runs richer than normal which should get lower NX.
Keep us posted.
Could be you have some thing not seen before.
Are the HC reading ok?
