2. Throttle Position Sensor (TPS): The TPS provides information to the Engine Control Module (ECM) about the position of the throttle plate. If the TPS is faulty or misadjusted, it can send incorrect signals to the ECM, causing the engine to stall.
3. Vacuum Leaks: Vacuum leaks can cause the engine to run lean, which can lead to stalling. Check all vacuum hoses and connections for leaks.
4. Fuel Pressure: Low fuel pressure can cause the engine to stall. Check the fuel pressure to ensure it is within the manufacturer's specifications.
5. Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine, causing it to stall. Replace the fuel filter if it is dirty or clogged.
6. Mass Air Flow Sensor (MAF): The MAF sensor measures the amount of air flowing into the engine. If the MAF sensor is faulty or dirty, it can cause the engine to run lean and stall.
7. Oxygen Sensors: Oxygen sensors provide feedback to the ECM about the air/fuel mixture in the exhaust. If the oxygen sensors are faulty, the ECM may not be able to properly adjust the fuel mixture, which can lead to stalling.
8. Spark Plugs: Worn-out or fouled spark plugs can cause the engine to misfire, which can lead to stalling. Check the spark plugs and replace them if necessary.
9. Ignition Coils: Faulty ignition coils can cause the engine to misfire, which can lead to stalling. Check the ignition coils and replace them if necessary.
10. ECM Issues: In some cases, a faulty ECM can cause the engine to stall. This can be caused by a variety of issues, such as software glitches or hardware failures. If the ECM is determined to be faulty, it may need to be replaced.
