1. Idle Air Control (IAC) Valve: The IAC valve controls the amount of air that bypasses the throttle body, helping maintain a steady idle speed. If the IAC valve is faulty or dirty, it can cause the engine to stall when the clutch is depressed.
2. Vacuum Leak: A vacuum leak can cause the engine to run lean and stall when the clutch is depressed. Check for any leaks in the vacuum hoses or connections.
3. Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine, causing it to stall. Check the fuel filter and replace it if necessary.
4. Distributor: Problems with the distributor, such as a faulty ignition coil or worn spark plug wires, can cause the engine to stall when the clutch is depressed.
5. Faulty Clutch Switch: The clutch switch, which tells the engine control module (ECM) that the clutch is disengaged, may be faulty or misadjusted. This can cause the engine to stall when the clutch is depressed.
It is recommended that you have your vehicle inspected by a qualified mechanic to accurately identify the cause of the stalling and perform any necessary repairs.
