2.5 N52 Really rough cold start

So straight to the point. When i start my car cold it idle's so rough the engine shuts down and i have to start it again. I have to keep the car going with the throttle. When the engine is warm it only does a little shake for about 2 seconds and then it goes away. I've changed and done some maintenence on the car but clueless to this as this came after i changed the air mass sensor and
both vanos solanoids.

what i've changed in recent times:
-Vanos solanoid intake and exhaust
-Air mass sensor
-Large DISA valve
-Air filter
-Oil and oil filter

Running the car on 98 gas (norway) and 5w30 oil.

So if anyone have a clue to what's going on i would really appreciate an answer to this
