What Causes Frequent Stalling When Starting a Manual Transmission Car?
2 Answers
The reason for frequent stalling when starting a manual transmission car is releasing the clutch too quickly during startup. Below are the correct operating methods and precautions: Correct Operating Method: When starting the vehicle, first place the gearshift in neutral. After the engine starts, depress the clutch pedal, shift the gear lever into first gear to begin moving, then gradually release the clutch while simultaneously applying the throttle to start the car. Precautions: Finding the clutch engagement point is crucial. The engagement point is reached when the clutch is slowly released. The coordination between clutch and throttle needs to be adjusted according to the vehicle speed. Familiarize yourself with your vehicle's clutch critical point height and pay attention to lifting the clutch slowly. To ensure smooth shifting operations, throttle control is essential—do not press the throttle during gear changes.
I've been driving manual transmission cars for decades, and stalling at startup is quite common. The key issue is improper coordination between the clutch and throttle. Beginners often release the clutch too quickly without matching it with enough throttle, causing the engine to stall due to low RPM. It's even more troublesome on slopes, as gravity can cause the car to roll back, leading to a stall. I recommend practicing in a flat, open area. First, press the clutch and engage first gear, then lightly tap the throttle with your right foot to maintain around 1500 RPM. Slowly lift the clutch with your left foot until you reach the biting point, feeling a slight vibration in the car body before continuing to lift, and the car will move smoothly. With a few practice runs, you'll get the rhythm down—don't rush it. Once you're experienced, it becomes as easy as eating or drinking. For hill starts, use the handbrake for assistance: first pull the handbrake, then lift the clutch while adding throttle, and release the handbrake once the car starts moving—safe and steady.
