1. Fuel Pressure: Check the fuel pressure to ensure that the engine is receiving enough fuel. A low fuel pressure can cause the engine to stall.
2. Fuel Filter: A clogged or dirty fuel filter can restrict fuel flow to the engine, causing it to stall. Replace the fuel filter if it is clogged.
3. Air Filter: A dirty air filter can restrict airflow to the engine, causing it to stall. Replace the air filter if it is clogged.
4. Spark Plugs: Faulty or worn-out spark plugs can cause the engine to misfire and stall. Check the spark plugs and replace them if necessary.
5. Ignition Coil: A faulty ignition coil can prevent the spark plugs from generating a strong spark, causing the engine to stall. Check the ignition coil and replace it if necessary.
6. Oxygen Sensor: A faulty oxygen sensor can provide incorrect information to the engine's computer, causing it to adjust the fuel mixture incorrectly and leading to stalling. Check the oxygen sensor and replace it if necessary.
7. Idle Air Control Valve: A faulty idle air control valve can prevent the engine from maintaining a steady idle, causing it to stall. Check the idle air control valve and replace it if necessary.
If the stalling problem persists, it is recommended to take the car to a qualified mechanic for further diagnosis and repairs.
