Does anyone know (or know someone) that could give me pointers. I have scoured the net but failed to hurdle the wall of silence.
I have an Mot/emissions problem with our 57 C3 1.4 petrol, but the issues will not be make/model specific.
The emissions are so bad the tester aborted the tests. I have no MIL triggered, and only a stored fault code relating to a brake switch.
Here's the big 'but', and where I need help. I am sure I can see errors in the following live data graphs- my question is should these oddities bring on the MIL.

The RPM can be seen to vary, but engine status shows as 'idle'. The track 1 is showing flat line?

The down stream C02 sensor should be showing a fairly flat line. So either the sensor is duff or the Cat is US. (I think)
I have collected other shots of things I find odd, but bear in mind that I am completely out of my depth! But quotes from 500 to 2000 squid are making me swim!
Back to my question- should the anomalies I perceive throw up codes and trigger the MIL
