Engine knock help please
Hi can someone please help before I go crazy. So my 2010 E90 318i n43 had a misfire on cylinder 2 on WOT so I replaced coil pack and spark plug.
All good for a few hundred miles until I started getting a rough idle long crank start from cold and LTFT of -20. After a short period of time I would then suffer from an engine knock only when hot, so I replaced all injectors with index 11 and coded all problems cured except knocking at idle any advice welcome tia |
