2011 Infiniti FX 30S - could it be fixed by itself???

Merry Christmas all...
2011 Infiniti 30 diesel S 180k km's
Yesterday cold start: car started and after 3 seconds of shaking it stopped.
2nd attempt ok..a bit of white smoke.
Gave a throttle, nothing happened initially.
Car started accelerating slowly even with the foot on the bottom and between 2500-3000 rpms comes to life.
So no smoke, slow acceleration and sometimes shaking during acceleration until it catches the breath.
Im talking Croatian in the video, but you'll understand what am i saying.
I cleaned MAF- just to exclude the possibility of it giving the problem
No warning lights showing on the dashboard.
Hope it's some vacuum leak...nothing serious...
If someone faced the same problem please let me know.
Cheers

It turned out to be a water in the fuel. Dirty fuel from Shell station.
My car 🚙 is sitting a lot, water decant and came to the bottom. Pump pulled water and caused my problem. Im happy it isn't something else.
