- A clogged fuel filter can restrict the flow of fuel to the engine, causing it to stall.
2. Fuel Pump
- A weak or failing fuel pump may not be able to deliver enough fuel to the engine, especially when it is under load.
3. Idle Air Control Valve
- The idle air control valve (IACV) regulates the amount of air that bypasses the throttle body, thereby controlling the engine idle speed.
4. Throttle Position Sensor
- A faulty throttle position sensor (TPS) can send incorrect signals to the engine control unit (ECU), which can cause the engine to stall.
5. Vacuum Leak
- A vacuum leak can cause the engine to run lean, which can lead to stalling.
6. Catalytic Converter
- A clogged catalytic converter can restrict the flow of exhaust gases from the engine, causing it to stall.
7. Faulty Ignition System
- A faulty ignition system, such as a bad spark plug or ignition coil, can cause the engine to misfire and stall.
