I Finally got the car to the dealership yesterday. As I mentioned B4 I wanted the warranty to make it's first debut. It seems as if the bank 2 sensor 1 is the sensor that monitors the 4,5, and 6th cylinders. That's the upper stream. But in any instance, there is definitely a air/fuel management issue when you feel that rough idle. Let's see what the techs come up with. Staying tuned.
