How’s your tire pressure.  Didn’t you go tubeless?  While I was at my dealer (Hamlin’s) last week he mentioned that low tire pressure can adversely affect the traction control system.

That’s a good suggestion too Cam.
The symptoms would point down that path, but I reverted to tubes so as to get the whole lot up and running again. There was too much stuff spread around the shop. I have done a re calibration which is very straightforward, so that should have set that issue to rights.
This weekend I’ll put the iridium plugs on the shelf and throw in a set of NGK equivalents and properly check the plug leads/coil connections etc..
Also I’ll check that the extensions I put in the O2 sensor leads are sound and also correctly sealed from water or contaminant ingress. They are behind the sump near the oil drain, so would be in a position where they could get wet.
Again many thanks to all and sundry for your interest, but I’ll reiterate that for the vast majority of the time it runs perfectly, so I am factoring that into my thoughts when examining possible causes.
BTW..
I was joking about the lawn mower in the earlier post... :rolleyes:

Not yet but I will.
Problem there is that it feels like a partial loss and so intermittent.

those are the worst.  sometimes you wonder if you are just imagining the symptoms.

Ok...
The stumping continues..
I have taken off the sensors to check for any anomalies in my previous work and noticed that the female plugs on the end of the O2 leads are not identical.
One is labelled “O2” and one is “O4”,





I do not for one second think that the Oxygen one one side is a diatomic molecule and the other side is quadratomic  :rolleyes:
But..
Does anyone have an inkling as to why they are not absolutely identical?
I embarrassingly admit that I did not take adequate care to keep the right and left labelled so as to ensure correct re fitment, but I have labelled them upon removal this time for reference.
I do note however, that they are the same part number, so the different coding on the plugs is probably an in house supplier reference...Or something.. :popcorn:
