Mercedes-Benz E320 engine sputtering intermittently when approaching traffic lights on Mercedes-Benz E320

Some Mercedes-Benz E320 owners report experiencing intermittent engine sputtering when approaching traffic lights, which can be attributed to several potential issues. These include problems with the fuel system, such as clogged fuel filters, malfunctioning fuel pumps, or faulty fuel injectors that may require cleaning or replacement. Additionally, engine misfires caused by defective spark plugs or ignition coils are common and can negatively impact performance and fuel efficiency. Some owners also report recurring electrical issues that, while complex, are distinct from problems seen in other models like the SLK200. If sputtering persists, it is crucial for owners to seek a professional inspection, as neglecting the problem could lead to serious consequences such as damaged catalytic converters, increased emissions, or severe engine damage over time.
