Seem to be missing some data.
First graph with the engine idling is perfect.
2nd graph the only problem I see is Bank 1 sensor 2 giving a low signal.
Front sensors says there not a lot of oxygen when it's high. Rear sensor constantly says there's a lot of oxygen in the gas. Either sensor defect, wiring problem, heater problem or a leak in the catalyst where oxygen can enter into the gasses.
Bank 2 seems to be reacting as expected when the catalyst is cold that is. Otherwise this catalyst is deteriorated a lot.
The only other thing is that when accelerating the oxygen sensors are quite slow. But that could be another problem causing this.
Do you have DTC's set? If so, which one(s)?
What are the complaints? High fuel usage? Engine hesitating?
