Is there a relationship between battery voltage and tickover on the K series? My 7 has had a very variable tickover for a while, sometimes working OK, others stalling at every opportunity unless duditious heel & toeing was used to keep the engine revving.
I had to fit a new battery and it started ticking over perfectly! One exception only when I had been stuck in stop/go traffic for a considerable time, immediately prior to parking for the day, when I set off for home [presumably the battery was a bit low on charge] the lumpy tickover returned until I got on the open road for half an hour - charging the battery - then running sweetly again...
