Weird Misfire on START engine

Hello
I have 235M 2016
The last two weeks as I drive the car I have strong SHAKES in the car
Sometimes he also switched off. Happens when the vehicle is off \ or COLD START
Sometimes, if I push the throttle a little bit it balances

I connected OBD to ISTA. And I found that every time there is a MISFIRE from a different cylinder
Still, I switched to 6 new plugs. But still the same problem

When I reset faults, and motivate. The vehicle is excellent!

I read in the forum about previous issues, the problem in INJECTORS.
My question, if the problem is with Injectors, why does MISFIRE move to another cylinder every time? After all, if INJECTOR malfunctioned, the malfunction would be in one cylinder. But they are changing

Is there a way to check Injectors?
Can example INJECTOR, of cylinder number 4, affect cylinder 6 \ 5 \ 3 \ 2 \ 1?

Thanks for responding

Before checking injectors, I'd check/replace the coil packs. Even though they usually don't all go out at once, so if you see same one or two cylinders misfiring replace the coil in those.
