Everything was on the bench throughly cleaned or replaced, passed the miss it runs like a sports car it hammers along.

Nice to hear it's sorted.
So what was the cause you, he recons ????
IF IT'S NOT A NISSAN.
THEN IT'S A COMPROMISE
It runs well once you pass the point of the missing, still runs like s@$# between 1800/2100 rpm.
Have heard of the temp sensor under the thermostat causing engine running issues. Do you know when it was last replaced?
Ok so once the engine revs passed the miss it's good.
You sound like you have a very similar problem as I do.
First I replaced the standard type spark plugs with Iridium plugs 1 range colder of course.
that made a big difference to idle problem.
Mind you I've tuned sons car perfectly on std type plugs.
Don't think plugs are the real problem, but something that is wanting as an connected underlying issue.
Currently looking at coil feed voltage.
remember reading that can be an issue.
maybe see this, may give you some ideas.

Well our regular mechanic took it for a run today and without hesitation he said its a lean mixture seems electric symptoms but definitely lean mixture so out with injectors tomorrow. Fitted a new coil yesterday made the starting a lot better 1st turn and vrrrooooom.
Does it have a miss on LPG also? If it does then cleaning the injectors isn't going to fix your issue. Have you replaced the coolant temp sensor? Sounds insignificant, but when one of these gives up the ghost, it will wreak havoc on the electricals.
The lpg is lean but we know that and will be sorted Friday coolant sensor is good its been tested, although not sure of the thermostat.
Faulty o2 sensor maybe?.

Sensor is new, injectors being removed cleaned and checked.
