My rover gauge readings

[nigegas]

Hi all
Last week my supercharged Chim 4ltr started to miss fire so I replaced all the usual dizzy cap & arm Lucas parts
New plugs and put a new set of kv85 leads on her and a air filter also managed to pick up 6 new plug extenders
I was lucky to get the 6 as it seems no one has any in stock
It seems I have cured the miss fire so far I've just bought a rover gauge all a bit new to me so I pluged it into
The ecu and this is the readings I have at the moment it seems the stepped motor is not working as it should
And the lambda readings also it did come up with a fault code 44 lambda sensor even
Your thoughts and views please

As it says- the lambda probe is not switching, so the fuel trim has max'ed out trying to get it to switch. Swap the probes over and see if the fault changes side.
