The only O2 sensor reading i can see on that print out is Bank 1 sensor 2 which is the sensor after the cat that one doesn't move much as it's reading the exhaust gas after the cat has filtered it, you need to know what the sensor before the cat (bank 1 sensor 1) is doing thats the one you've been playing with this is the one that controls the fueling and is the one that fluctuates constantly when the engine is warm up and idling can you bring that reading up on your scanner
