- A failing fuel pump or a clogged fuel filter can lead to a loss of fuel pressure, causing the engine to stall while driving.
2. Ignition System Failure:
- Faulty spark plugs, ignition coils, or a malfunctioning distributor can disrupt the proper ignition sequence, leading to the engine shutting off.
3. Faulty Oxygen Sensor:
- A faulty oxygen sensor can provide incorrect air/fuel mixture data to the engine control unit (ECU), resulting in an improper combustion process and engine stalling.
4. Crankshaft Position Sensor Failure:
- A faulty crankshaft position sensor disrupts the ECU's ability to determine the engine's position and timing, leading to engine stalling.
5. Throttle Body Issues:
- A dirty throttle body or faulty throttle position sensor can lead to inconsistent fuel and air mixture delivery, potentially causing the engine to stall.
6. Vacuum Leak:
- A vacuum leak can disrupt the proper air/fuel mixture balance, leading to rough engine performance and stalling.
7. Electrical Problems:
- Electrical issues such as a loose or damaged wire, faulty relay, or electrical component can disrupt essential electrical circuits and cause the engine to shut off.
8. Clogged Catalytic Converter:
- A clogged catalytic converter can restrict the flow of exhaust gases, affecting engine performance and potentially leading to stalling.
9. Transmission Issues:
- In rare cases, transmission problems such as a slipping or defective automatic transmission can cause the engine to stall while driving.
10. Engine Control Unit (ECU) Failure:
- A malfunctioning ECU, which is the car's computer controlling many engine functions, can lead to various issues, including engine stalling.
