Spark plugs play a crucial role in igniting the air-fuel mixture in your car's engine. When they become worn or fouled, they can cause the engine to misfire, leading to rough running and stalling.
2. Ignition Coils
The ignition coils are responsible for delivering high voltage to the spark plugs. If the coils are faulty, they may not produce enough voltage, leading to weak or intermittent sparks, which can cause your car to stall.
3. Fuel Injectors
Fuel injectors are responsible for delivering the right amount of fuel to the engine's cylinders. If they are clogged or dirty, they may not be able to deliver enough fuel, causing the engine to run lean and possibly stall.
4. Fuel Filter
The fuel filter is responsible for removing contaminants from the fuel. If the filter is clogged or dirty, it may restrict the flow of fuel, causing the engine to run lean and possibly stall.
5. Air Filter
The air filter is responsible for removing dirt and debris from the air that enters the engine. If the filter is clogged or dirty, it may restrict the airflow, causing the engine to run rich and possibly stall.
6. Engine Coolant Temperature Sensor
The engine coolant temperature sensor is responsible for measuring the temperature of the engine coolant. If the sensor is faulty or damaged, it may send incorrect temperature readings to the engine computer, which can cause the engine to run rich and possibly stall.
7. Faulty Oxygen Sensor
The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases. If the sensor is faulty, it may send incorrect readings to the engine computer, which can cause the engine to run rich or lean and possibly stall.
8. Vacuum Leak
A vacuum leak is an unwanted opening in the intake manifold or other vacuum lines that allows air to leak into the engine. This can cause the engine to run lean and possibly stall.
