Well.the omens are good. Started first turn of the key last evening when I collected her from the garage and, even more significantly, first turn this morning even though it is cold outside (well, as cold as it gets here!). I took her straight to "Cut Out" roundabout and no problems whatsoever and she seemed to running more smoothly and evenly but, of course, we have to allow here for auto-sugguestion on my part! So, cautious optimism, I'll take her for another run later on and I'll keep you all informed.
