Why does a car suddenly stall while driving?
1 Answers
Reasons why a car suddenly stalls while driving: 1. The engine fuel injector is clogged or the engine fuel pump is blocked, preventing normal fuel supply. If the vehicle is coasting in neutral (N gear), the engine may stall; 2. When idling in neutral (N gear) while driving, the engine draws air through the throttle bypass valve. If it closes, the engine's air intake becomes zero, leading to no gas supply in the engine cylinders and causing a stall; 3. The vehicle battery is completely damaged or the battery terminals are not securely connected, showing signs of looseness. The engine cannot properly inject fuel through the fuel injector, potentially failing to start normally, resulting in abnormal engine operation and stalling.
