I have an issue with my 650i misfiring. I’ve replaced all of the plugs and coils and the issue persists. While parked I can revv the engine all day and it’s completely fine, however if the vehicle is under any kind of load, accelerating, going up a hill, and going above 2000 RPM it will sputter/misfire. I’m not sure what else I can do, I’m thinking it may be a fuel issue. It doesn’t throw a CEL however on BimmerLink it’s showing that it’s detecting misfires on 1, 2, and 4 intermittently. Any input would be greatly appreciated!
