Dodge B2500 engine bogs down and backfires at highway speeds, occasionally shutting off on Dodge B2500

Some Dodge B2500 owners report experiencing issues with their engine bogging down and backfiring at highway speeds, which can occasionally lead to the engine shutting off. These problems may stem from a lack of acceleration, chugging, hesitating, or misfiring, potentially caused by issues within the fuel system, air intake system, or ignition system. Additionally, some owners notice that backfiring and bogging down often occur after the vehicle has been parked in hot conditions, suggesting that temperature may play a role. Symptoms like intermittent stalling, difficulty starting as the day progresses, and loss of power when accelerating are also reported. Furthermore, some owners have identified possible causes such as a misfire due to a broken exhaust manifold bolt or a collapsed valve lifter. To address these concerns, it is advisable for owners to check the fuel, air, and ignition systems, investigate the exhaust manifold and valve lifter, perform routine maintenance, and consider environmental factors that may trigger these issues.
