- Fuel Filter: A clogged fuel filter can restrict the flow of fuel to the engine, causing it to run lean and stall.
- Fuel Pump: A failing fuel pump can also cause fuel starvation and stalling.
- Mass Air Flow Sensor (MAF): A faulty MAF sensor can provide incorrect readings about the amount of air entering the engine, which can lead to the air-fuel mixture being incorrect.
- Oxygen Sensor (O2): A faulty O2 sensor can also affect the air-fuel mixture, causing the engine to run lean or rich.
- Spark Plugs and/or Wires: Bad spark plugs or wires can cause the engine to misfire, which can also lead to stalling.
- Idle Air Control Valve (IAC): A faulty IAC valve can cause the engine to idle too high or too low.
Since the "Service Engine Soon" light is also on, it would be helpful to have the car scanned for diagnostic trouble codes (DTCs). These codes can indicate which component or system in the engine is causing the problem.
Once you know the specific DTCs, you can start troubleshooting and replacing the faulty components as needed.
