Hi all i was driving around today while running the torque pro app and was reading the voltage on my o2 sensors on my vf 6ltr . The bank 1 was fluctuating between .8 and .1 fairly quickly whilst bank 2 would fluctuate a lot slower and at times sat at .7 or .8 this was whilst cruising at about 1700 rpm . When putting my foot down the both read .9 and when coasting up to the lights both read 0 . Is my bank 2 sensor just getting lazy ? Thanks .
