What Causes Frequent Car Stalling?
2 Answers
Reasons for frequent car stalling: 1. Use of low-quality fuel causing engine carbon buildup leading to stalling; 2. Damaged fuel pump or obstructed fuel lines; 3. Clogged fuel injectors or abnormal fuel pressure causing stalling; 4. Driver's lack of proficiency or improper operation may also result in stalling; 5. Faulty spark plugs or ignition coils. Solutions for stalling: 1. At idle speed, the car doesn't move quickly—simply restart the engine after stalling. For automatic transmission cars, shift to Park or Neutral before restarting; 2. If stalling occurs while coasting, maintain steering control while gently applying brakes. Manual transmission vehicles should depress the clutch, engage the appropriate gear, then release the clutch to let the vehicle's momentum restart the engine. Automatic transmission cars need to shift to Neutral before restarting the engine.
My car had this issue before, and after a long check, it turned out to be insufficient fuel supply from the fuel pump. The car would suddenly stall while driving, especially noticeable on uphill sections. The mechanic said that aging spark plugs or ignition coil problems could also cause similar symptoms and recommended a complete replacement. Additionally, a clogged fuel filter, an air intake system leak, or a faulty mass airflow sensor could be the culprits. I remember one time when the battery terminal was loose, the car stalled at a red light and wouldn't start—these small details also need regular checks. If the problem occurs right after refueling, fuel quality issues should also be considered.
