Hi community. Can anyone help me with an opinion about the values in the pictures related to the oxygen sensor? The values highlighted in red are from my car and those in blue from a similar car that I found on the internet. I don't have any engine lights on in the dashboard but I have problems with the unstable idling with vibrations.

The screen dump does not really sy anything useful since these values change every sceond, what do you suspect to be an issue regarding the catalyst temperature?
To me it looks normal.

For me the B1S1 catalytic temperature sensor always shows 900 degrees Celsius, which is abnormal. Secondly, the AFR value is 28.99: 1 compared to 14.7: 1 which is normal. Also, the O2 sensor equivalence ratio value is 1,9526 compared to 1 as is normal.
