Why Does Car Stall?

Car stalling is a common issue that many drivers in the United Kingdom face at some point. It can be frustrating and potentially dangerous, especially in busy traffic or at high speeds. Understanding the reasons behind car stalls can help prevent them from happening and ensure a safe driving experience.

One of the main causes of car stalling is a faulty fuel system. This can be due to a clogged fuel filter, a malfunctioning fuel pump, or even a dirty fuel injector. When the fuel system does not function properly, the engine does not receive the necessary amount of fuel, leading to a stall.

Another common reason for car stalls is a malfunctioning ignition system. This can be caused by a faulty spark plug, ignition coil, or distributor cap. If the spark plug does not ignite the fuel-air mixture properly, the engine will stall.

Furthermore, issues with the electrical system can also lead to car stalling. A weak battery or faulty alternator can cause a loss of power, resulting in a stall. Additionally, problems with the sensors, such as the oxygen sensor or crankshaft position sensor, can also contribute to stalling.
