What Causes the Engine to Stall When Releasing the Throttle?

[LaCassandra]

The reasons for the engine stalling when releasing the throttle are: 1. Fuel pressure too low, air filter clogged, injector atomization or leakage, improper idle adjustment, poor spark plug performance, air flow meter failure; 2. Internal engine injector dripping or clogging, electrical circuit failure, or insufficient fuel injection; 3. Throttle carbon buildup issues. The throttle is a control device for regulating engine power, part of the vehicle's fuel supply system. By adjusting the pedal pressure, it controls the throttle valve opening, regulates air intake, with the computer managing fuel quantity, thereby controlling engine speed. Additional information: The throttle's function is to control the cylinder's filling volume by adjusting the carburetor's throttle opening and to regulate the fuel flow through the fuel regulator, determining the engine's output power and generating thrust.
