What Causes a Car to Stall While Moving?
2 Answers
The reasons for a car stalling while moving are: 1. Electrical circuit failure; 2. Short circuit in low-voltage wiring; 3. Component failure; 4. Fuel system failure; 5. Issues with the engine overheating and anti-knock system; 6. Malfunctions in the car's ignition system, starter switch, or fuses. The solution is to immediately go to a professional shop for repair or replacement, such as cleaning engine carbon deposits. A car stalling while moving is mainly caused by using inappropriate fuel. It is recommended to add a certain amount of cleaner when refueling. Additionally, after cleaning, it is advisable to drive at high speed for a while, as this helps increase exhaust flow, allowing stronger airflow to carry out larger carbon deposit particles.
As a seasoned driver with years of experience, I believe the most common cause of stalling while driving is running out of gasoline. Many drivers fail to pay attention to the fuel gauge and only realize they need to refuel when they're already on the road. Fuel pump failures are also quite common—without proper fuel supply, the engine will stop working. Worn-out spark plugs or faulty ignition coils can particularly cause stalling during acceleration or uphill driving. Last time on the highway, I experienced this and found it was due to poor relay contact. The safest action after stalling is to immediately turn on the hazard lights and pull over; never force a restart to avoid engine damage. Regular checks of the fuel system and ignition system can significantly reduce such troubles. Remember these tips for a more worry-free drive, especially on long trips—always keep an eye on the dashboard warnings.
