Labda sensor earth problem

There's nearly always a logical explanation to these things, great to hear you've found the culprit.

Finally I got the Chimaera (barely) through MOT and emission control. Using Rover Gauge verified that bot left and right bank was controlled by the lambda sensor. Now I got a new phenomenon with a small black box attached to the steering column that is ticking as an ancient clock, but that have to be in another thread.
