Finally managed to login/reset forum pass. Sorry delay.
Guys in local garage sorted this out last week - they changed one coil and tightened up a gasket: air intake --> throttle body.
I should find new gasket because revs are dropping occasionally below 500.. but seriously looks like no misfire from cold start anymore and torque is good all round revs
To answer you mate:
Had very bad fuel consumption from cold (~ 10mpg) until it gets warmed up and fires up all cylinders.
Air flow meter and AAC cleaned.
ECU is original as are all other parts except coilpacks (got them from UK Rising Sun Performance a couple years ago).
I've tried all usual tricks found on this and Australian forums as much as I could on parking lot with my amateur skills.. but these guys in garage
did it slowly with dedication and friendly attitude testing all parts for many days :O
Engine compression is tested good no probs in there.
Strange fact is that this is second coil changed in past 2 years despite replacing wiring loom as well. Would be still nice to buy all 6 original Nissan coils and visit a real specialist whose equipment can fully read my ECU.. to understand all parameters / professional check-up in Germany or Austria somewhere..?
Next week getting new Timing belt.. hopefully installation goes well w/o complications
