Oxygen sensor is showing the same problem as the gas analyzer. Mixture is a bit too rich.
Front Oxygen sensor signal should be switching between low (0.1-0.2V) and high (0.7-0.8V).
Rear Oxygen sensor should be a steady 0.8 volt.
Make sure you look at the correct Oxygen sensor. You have 2 of those.
Check the pid called Fuel System. Is the car in "closed loop"?
Check the coolant temperature reading.
Catalytic convertor is unable to convert CO into CO2, because of the rich mixture there's no Oxygen left in the gasses. So, maybe when you correct the mixture problem, the cat will work again.
