What to Do If the Vehicle Stalls Suddenly While Driving?
1 Answers
If the car stalls suddenly while driving, depending on the road conditions at that time and if there is no emergency, you can slowly apply the brakes to prevent a rear-end collision. After the speed decreases, steer slowly to move the car to the roadside lane. Once parked at the roadside, turn on the hazard lights, set up the warning triangle, and call for a tow truck. Common causes of stalling are as follows: 1. Stalling due to carbon deposits: Especially at the electronic throttle, this is an intake system fault. When there is excessive carbon buildup at the throttle, releasing the accelerator while driving may cause the engine to stall, which often occurs in very old cars. However, this can be prevented. Normally, you may notice difficulty starting the engine, or even needing to press the accelerator to start it—these are signs of excessive carbon deposits at the throttle, which require timely cleaning. 2. Fuel supply failure: Usually caused by a damaged fuel pump, which cannot pump fuel. The fuel pump has a long lifespan, so damage typically occurs in older cars. Some fuel pumps fail while the car is parked, making it impossible to start, while others fail during driving. 3. Power supply failure: Usually caused by a damaged ignition coil, resulting in no high-voltage electricity to all spark plugs.
