One possible cause of engine misfiring in a BMW 3 Series is a faulty ignition coil. It is important to have all of the ignition coils checked and replaced if needed.

Another possible cause could be a clogged fuel filter. I recommend having the fuel filter replaced and the fuel system checked for any other potential issues.

S

A faulty oxygen sensor can also lead to engine misfiring. I suggest having the oxygen sensor checked and replaced if necessary.
