What Causes the Engine to Stall When Accelerating?

[MorganFitz]

The reasons why the engine stalls when accelerating are: 1. The throttle body is dirty, causing the throttle plate to open insufficiently or get stuck, leading to stalling; 2. The ignition coil is damaged, with an open or short circuit; 3. The fuel filter is too dirty; 4. The mass airflow sensor is faulty; 5. The fuel pump cannot maintain proper fuel pressure or the fuel injection is insufficient during driving, resulting in stalling during acceleration. The throttle is a control device that regulates the engine's power (thrust). In piston aircraft engines, the throttle controls the carburetor's throttle plate opening to adjust the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle regulates the metered fuel flow through the fuel controller, determining the thrust produced by the engine.
