F30 328i Startup problems

Zmajzlik · 10-19-2023, 02:47 PM

Hi guys!

Since it started to get colder this car after firing up works unevenly.

After putting it in gear, the revs start to drop, and sometimes the car sometimes stalls.

I've already put new spark plugs and 2 ignition coils.

I wonder that someone have same problems as I have and maybe found the solution..

As is always the case the first step is pulling codes with a code reader.

I had the same issue. Cleaning my injectors fixed it
