Hi
Thanks for replying.
My Micra is 2006 with 105,000 miles.
I underestimated the idle speed a bit, it is probably more like 600.
It is just a bit of a pain having had 2 things done, so which is the one that upset things? I was thinking that if the mechanic who did the dump disconnected the battery could that do it?
I have a decent independent Nissan garage in Lincoln, perhaps a visit to them.
