Why Does the Engine Suddenly Stall?
2 Answers
Reasons for sudden engine stalling: 1. Electrical circuit issues; 2. Spark plug problems: Spark plugs are wear parts that require regular replacement. If used for too long, the electrode gap will widen, affecting ignition energy. Weak ignition energy prevents the combustible mixture in the engine from burning completely; 3. Ignition coil issues; 4. Air intake problems; 5. Fuel injection problems: If the fuel injection system malfunctions, the engine's fuel supply becomes abnormal, and the car's engine cannot operate properly. When the car's engine fails, it should be taken to a professional facility to read the fault codes, which can help technicians quickly identify the cause and location of the issue.
After driving for so many years, sudden engine stalling is really annoying. Common causes include fuel system issues like a broken fuel pump or clogged fuel lines, leading to interrupted fuel supply; there are also ignition system failures such as severely worn spark plugs failing to ignite, or insufficient power from the alternator or battery, causing the car to lose power and stall instantly. Malfunctioning sensors like the crankshaft position sensor can also confuse the computer about the combustion timing. A dirty air filter can affect air intake. Sudden engine stalling while driving is very dangerous and can easily lead to accidents. Remember to pull over, turn on the hazard lights, and check the dashboard warning lights. In most cases, it's necessary to quickly find a professional shop for inspection and repair. Regular use of high-quality engine oil and periodic replacement of filters can prevent some of these issues.
