O2 sensor fault codes
I have CEL and did a check with a Durametric tool which showed:
34: Oxygen sensing range 2||Cylinder (4-6)
26: Oxygen sensing range 2||Cylinder (1-3)
Unfortunately, Duramtetric said they cannot determine which O2 sensors have gone bad like before or after the Cats. Anyone else with a similar situation or any recomemdations. BTW, the car is a 1996 C2 with 37K.

Are the post cat sensors even monitored? I thought the pre cat sensors were the critical ones?
Strange that errors would pop on both banks at the same time.
37K is awful low mileage for O2 sensors to be going bad. I'd be looking at wiring and/or connections.

aren't 34 and 26 fuel and air mixture control codes?
if it is the sensors, since you have durametric already why not try the actual values(I think that's the tab) and check the boxes for the o2 sensors before and after cat both banks. you'll get values while driving around that can be saved to a file so you don't have to stare at the laptop. maybe the readings will give you more info on which if any sensor is bad.
