Cylinder 4 misfire codes. Sputtering, running rich
Getting multiple misfire codes, all pointing to Cylinder 4. When around 50% pedal, I get a sputter and eventually limp mode until I clear the codes.
Replaced plugs 2k miles ago Delphi coils installed 40k miles ago Still stock Fuel injectors. 85k miles, would a single fuel injector failure cause this problem? Running rich and sputtering? Log attached, FBO w/ backend custom flash. Haven't changed settings, this started yesterday. Codes: 2EFE = Random/Multiple Cylinder Misfire Detected 2F02 = Cylinder 4 Misfire Detected 2EE0 = Combustion misfiring, several cylinders: Fuel injection deactivation 2EED = Combustion misfiring, cylinder 4: Fuel injection deactivation EDIT: can't attach CSV log.

Issues on cylinder 6 spluttering at speed, got worse, engine codes
Hi
I have a 135 coupe 2009 N54 49000 miles. New ish to me so issues not of my doing. I had same sort of issues turned out had cracked spark plug insulator. A couple of worn tips on plugs. Some over enthusiastic filling of the oil had filed a plug hole. And some residue between a coil and wall of coil hole. Cleaned it all up, changed plugs and coils as history unknown, suspect original to car from plug wear, cleared codes etc.( mate next door has diagnostic tablet thing) So far so good no issues, smooth running again. Good luck hope this helped |
Appreciate
