When i start my 335, it seems to missfire (mostly cyl 6) temp can usually range from 30f to 57f. Once warm, seems to run fine.

Replaced injectors, spark plugs/ coils

What are your bank 2 fuel trims at idle?

It's probably your fuel injectors. You can pull them out and get them tested for a poor spray pattern.

My mistake. I skimmed through your post quick and didn't realize you mentioned your injectors as well.

With those three things out of the way it starts to become more difficult to pinpoint what the issue could be, as there are a multitude of different potential causes. Have you gotten the car scanned with a BMW scanner yet?

First step is to check the fuel trims like the guy said. Does your car seem hard to start when cold, like a long crank? how's your fuel pressure looking?
