Recap.

- Rough Idle (even with all stock parts)
- Dealership claims is normal
- Similar Camaro does too, but not as hard as mine

I've been playing with Torque for Android (Awesomesauce) and ran a few diagnostics. One of the geenric tests posted this a a failure

MID:$21 TID:$66
- Catalyst Monitor Bank 1
Max: 40,978 Min: 26,816
Test result value: 6,624
FAIL

Bank #2 passed. This whole week I have been monitoring my O2 sensors. Here is a graph of the engine load, O2 sensor bank 1, O2 sensor bank 2 while at a steady idle.

Is this normal? Is it possible my O2 sensor is going bad and causing the rough idle?
