What is the situation with BMW multi-cylinder misfire?

[SanChase]

BMW multi-cylinder misfire may be caused by spark plugs losing ignition capability, throttle malfunction, or engine carbon buildup issues. Carbon deposits can lead to multi-cylinder misfire: causing engine vibration problems. Engine carbon deposits have significant impacts on vehicles, primarily by reducing engine power - resulting in uneven power output and gradual attenuation, making the engine increasingly powerless. It also increases fuel consumption, adding to economic burdens. Spark plugs losing ignition capability causing multi-cylinder misfire: manifests as cold start difficulties, meaning hard ignition and difficulty starting the vehicle. Severe cases of combustion chamber carbon buildup may even cause cylinder knock, producing noises during low-speed acceleration, damaging pistons and crankshafts, leading to engine overheating which severely compromises vehicle safety. Furthermore, it causes excessive emissions, not only failing annual inspections but also directly worsening environmental pollution hazards.
