Why Does the Car Stall While Driving?
2 Answers
The reasons for a car stalling while driving are: 1. Inexperienced driving skills or improper operation; 2. Fuel pump stuck or malfunctioning, causing poor fuel supply; 3. Use of low-quality fuel leading to excessive engine carbon deposits; 4. Faulty spark plugs or ignition coils resulting in multiple cylinders not firing; 5. Excessive dirt on the idle motor valve core and throttle body. Solutions for car stalling include: 1. Quickly break in the car and improve driving skills; 2. Use qualified fuel; 3. Clean the fuel system, injectors, and fuel tank; 4. Clean the throttle body; 5. Clean the idle motor; 6. Replace engine oil and oil filter.
Engine stalling while driving is quite common. I've encountered it several times, mostly related to the fuel system – like an empty tank causing fuel pump failure, or a clogged filter starving the engine, which can make the car suddenly shut down. Another possible cause is ignition system issues, such as worn-out spark plugs failing to ignite or faulty ignition coils, especially prone in rainy or humid conditions. The electrical system is also critical; a dead battery or malfunctioning alternator can lead to insufficient power supply, triggering an automatic shutdown. Faulty sensors are troublesome too – small probes like the crankshaft position sensor failing can disrupt the ECU's engine control. Whenever this happens, I immediately shift to neutral, pull over, and check basics like the fuel gauge and battery warning light. If I can't fix it myself, I call for professional assistance. Regular maintenance, like oil changes and filter cleaning, significantly reduces stalling risks.
