OK, FV appears to be inoperative. ie No "buzz" I can feel a slight vibration, but I would expect that to be just the fuel pump whirring

I have disconnected O2 at plug and reconnected. No change in either condition. I will try earthing and 1.5V as per Wayne's O2 advice. Then will work my way through O2 relays and speed relays and fuses etc.

Brian, if we set the AFR at idle at 13.0-13.5 ( I assume by using the mixture screw and idle speed screw), with the Lambda disconnected, how will the AFR look at high ie+3500 rpm when Lambda system is bypassed by speed relay? Or do we disconnect Speed relay too?

I do however, intend to sort out Lambda system anyway, but as a stop gap to use the vehicle, and my own knowledge,
