1 Answers
Reasons for a vehicle stalling when the throttle is released include: 1. Fuel pressure too low, air filter clogged, injector atomization or fuel leakage, improper idle adjustment, faulty spark plugs, air flow meter malfunction, etc.; 2. Fuel injector dripping or clogging inside the engine, circuit faults, or insufficient fuel injection; 3. Carbon buildup in the throttle body. 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, manages air intake, and allows the computer to regulate fuel quantity, thereby controlling engine speed.
