1. Low Idle Speed: The idle speed of your car may be too low, causing the engine to stall when you release the clutch. Check your owner's manual for the recommended idle speed and adjust it if necessary.
2. Faulty Idle Air Control Valve (IACV): The IACV regulates the amount of air that bypasses the throttle valve when the engine is idling. If the IACV is faulty, it can cause the idle speed to be unstable and the engine to stall when you release the clutch.
3. Vacuum Leak: A vacuum leak can cause the engine to run lean, which can lead to stalling when you release the clutch. Inspect the vacuum hoses for cracks or leaks and replace any that are damaged.
4. Dirty Throttle Body: A dirty throttle body can restrict airflow and cause the engine to stall when you release the clutch. Clean the throttle body and make sure it is free of debris.
5. Faulty Fuel Injector: A faulty fuel injector can cause the engine to run lean, which can lead to stalling when you release the clutch. Test the fuel injectors and replace any that are not functioning properly.
