Mercedes-Benz Sprinter 2500 engine stalls at stop signs with fluctuating RPMs on Mercedes-Benz Sprinter 2500

Some Mercedes-Benz Sprinter 2500 owners report experiencing engine stalling at stop signs accompanied by fluctuating RPMs. These issues may stem from various factors, including problems with the fuel system, such as a malfunctioning fuel pump or delivery system. Additionally, a dirty air filter can restrict airflow, leading to stalling, which can be remedied by replacing the filter. Owners also report that a faulty ignition system, characterized by worn spark plugs or ignition coils, can contribute to these stalling incidents. Furthermore, some drivers notice that poor acceleration and rough idling may indicate a vacuum leak, which disrupts the air-fuel mixture necessary for proper engine function. Lastly, issues with the crankshaft position sensor can lead to starting difficulties and rough idling, resulting in stalling. Addressing these potential causes is crucial for diagnosing and resolving the stalling issue effectively. Regular maintenance and timely repairs are recommended to ensure optimal performance and prevent future occurrences.
