There are two procedures - Throttle valve closed Position learning and Idle Air Volume Learning to be performed both procedures are listed in the manual with the link above

Thanks Timeshock- will check it out. Thumbs Up

I'm kind of sometimes good at 'fixing things that aren't always broken' -thinking will make the car better but seems sometimes it can disturb things also.

Would that be idle reset/ relearn? Does this happen sometimes when people clean the TB/ butterfly?
Have heard that if you touch or disturb the butterfly then you may have to do idle reset?
Is this true?
Was going to clean my P11 TB but maybe I will not bother if I could upset it - what is the situation exactly and how do you do an 'idle reset'- if that is what maybe needed? Does it have to be done by Nissan themselves or can anyone do it?

Diy but do take the throttle body off...and behind it the maf sensor can be unscrewed.
It's quite a hardy maf sensor but i managed to kill one.

Yea, thanks Matt- I already had the MAF off and cleaned that twice in a year, 2nd time it did not even need cleaning. Mine too seems to have survived the cleaning ok but luckily is a hotwire type rather than the film type, which seem like they are much more sensitive to cleaning and getting damaged in the process.

Not done the TB / Butterfly though or Idle Control Valve, will look at the re-learn procedure in the manual- just incase I do upset anything.
