What Causes the Car to Stall When the Clutch is Depressed?
2 Answers
The reason why the car stalls when the clutch is depressed: It may be that after the clutch is fully depressed, the clutch does not disengage, making it easier to stall. The clutch cable or clutch disc should be replaced immediately. The clutch is the medium that transmits engine power to the gearbox. Its assembly includes the clutch plate, clutch pressure plate, release sleeve, release bearing, return spring, clutch cable, clutch release fork, etc. The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During driving, the driver can depress or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the gearbox, thereby cutting off or transmitting the power input from the engine to the gearbox.
I've been driving manual transmission cars for many years, and stalling when releasing the clutch is quite common. Most of the time, it happens when you don't give enough throttle while operating, or release the clutch too quickly, causing the engine RPM to drop too low and stall. This is especially common when you're just learning to drive - it takes practice to coordinate the clutch and throttle properly.
Another possibility is vehicle issues, such as a dirty or aging idle control valve making the RPM unstable, causing it to drop when you press the clutch. For older cars, you should also check if the throttle body is clogged or has excessive carbon buildup - cleaning it usually helps. Spark plugs that haven't been replaced for too long can also cause unstable ignition, increasing the risk of stalling.
When driving, pay attention to the tachometer and avoid releasing the clutch too abruptly. With more practice, you can avoid stalling. This situation occurs more easily when starting a cold engine - letting it warm up for a few minutes before driving helps. While stalling is annoying, it's not a big deal once you master the technique.
