Which E90 are you referring to?

E90 320i

check the fuel lines bro. aku rasa maybe ade leaking sane so pressure from fuel pump not sufficient to the engine

Could also be ur ignition coils misfiring. Get it scanned

Sounds like spark plugs or ignition coils change would do the trick.

Many possibilities
1. Fuel pump
2. Fuel filter
3. vacuum leaks
4. MAF dirty
5. ignition sensor
6. coils / plugs

Sadly its hard to diagnose such issue.

I also suffer from engine vibration during morning start ups, already changed spark plugs but problem still persist,
might change the coil plugs

Ori BMW NGK Plugs is just RM40 each from Bavaria Auto and Ignition Coil is RM85 each.. Those are DIY possible

Guys, i also facing the same problem..but case i worst than that i think la.. almost 2 weekd at workshop. Semua tukar da tp still lg start enjin ada problem and somtimes power hilang bila jalan dan mati2. My mekanik pun pening..throttle body da tukar tp sama jugak. Adakah masalah pd ECU(control unit)

Epul2801, sounds like u need to tukar mechanic/worskhop.

Ignition coil can diy diagnose by pulling out to check for vibration. I always have extra ignition coil cause easily diagnose and replace.
