What causes sudden stalling during low-speed driving?

[DeclanAnn]

Here are the reasons for stalling during low-speed driving: 1. Fuel injector issue: Sudden stalling during low-speed driving can be caused by clogged fuel injectors. Poor fuel atomization due to clogged injectors can lead to abnormal engine operation and potential stalling. 2. Fuel system problem: Insufficient fuel pressure or a faulty fuel pump can also cause stalling. In such cases, it's important to maintain control of the steering and pull over to the side for inspection. Here are some extended solutions for stalling during low-speed driving: 1. Stay calm: Keep a firm grip on the steering wheel. You can choose to pull over by applying the brakes. For manual transmissions, try disengaging the clutch, shifting into the appropriate gear based on speed, then releasing the clutch to use the vehicle's momentum to restart the engine. 2. Braking deceleration: If stalling occurs due to braking while driving, you can increase braking force while monitoring surrounding conditions. If possible, change lanes to avoid obstacles ahead, as steering assistance may be unavailable at this time.

I've been driving for over ten years and have encountered several instances of the engine suddenly stalling at low speeds. The most common causes are fuel delivery issues or problems with the ignition system. Specifically, the fuel pump may be fatigued and unable to pump effectively, especially prone to failure under high temperatures; clogged fuel injectors can lead to insufficient fuel supply, or worn-out spark plugs may cause incomplete ignition. A dirty throttle body can also affect air intake, disrupting the air-fuel ratio. Faulty sensors like the mass airflow sensor can mislead the engine control unit. After stopping, first check if the battery is low on charge, then inspect the alternator. It's important to refuel at reputable stations, as poor-quality fuel can clog the fuel system; regularly replace the air filter and spark plugs, and don't delay maintenance. If the engine stalls, immediately pull over safely, turn on the hazard lights, stay calm, and prioritize safety.
