throretically thats a bit low however its cold weather at the moment and if it spins over fast i wouldnt worry too much about it.
i bet if you disconnected battery overnight it would still be similar voltage in the morning .
its something related to the idling running rather than it cutting out if you were on a motorway at a constant 70 all day long so that should eliminate fuel or many other issues.
same symptoms as a car with a carburettor having a blocked idling jet .will run forever at any engine speed other than idle.
keep at it !
Thank you!!
Now the ICV is swapped (was already clean, gave it a wee squirt of light oil just to make sure it was moving nice n free, before fitting) she still started awful. New info...
Idle appreciable struggles (approx 50-75rpm drop) when stationary and engage heated rear window, or even hold a couple of window buttons 'up'. I noticed this because the windows need reprogramming after the battery was disconnected this morning, doesn't normally murmur when I do this, from memory.
Also, on the first run round the block when I stuck headlamps on the MFD went black momentarily - which leads me to think charging issues.
Couldn't get her to stall, however,
maybe cured, maybe just lucky...
At idle, with load (h'lamps, heated seats and heated rear screen) 13.8v I think.
Oh, I see it's now raining. Well, that's good
