Some BMW 528i owners report experiencing cylinder misfires on multiple cylinders, specifically 1, 4, 5, and 6, which can lead to a significant loss of engine power and stalling under throttle. These misfires are often accompanied by rough idling, poor acceleration, and increased emissions, potentially causing damage to the catalytic converter over time. Many owners find that worn or defective ignition system components, such as coils, spark plugs, and fuel injectors, are common culprits behind these issues. Additionally, problems with the fuel pump, fuel filter, and injectors may arise, particularly if the vehicle has been operating on low fuel or poor-quality gasoline. Prompt diagnosis and replacement of affected components are crucial for restoring engine performance and preventing further complications.
