Who uses OBD2 software such as OBD Fusion.....
Car has been running rich and when cam/heads work was complete tuner reused O2 sensors...said my newly purchased O2 sensors did not work...anyway it ran fine but now I think the left bank sensor is not working...

With the OBD Fusion connected to the car the left O2 sensor is all over the place, ie, 20,85,57 but the right bank sensor is steady at 44-45..
Am I close on my assumption ????

Thanks,

Jim
