What Are the Reasons for Stalling When Starting a Manual Transmission Car?

The reasons for stalling when starting a manual transmission car are: 1. Use of unqualified fuel; 2. Blocked fuel lines; 3. Faulty spark plugs; 4. Abnormalities in the fuel injector and fuel filter; 5. Poor contact in wiring connectors; 6. Insufficient driving skills; 7. Short circuit or power failure in the engine or car computer; 8. Releasing the clutch too quickly when starting or going uphill; 9. Low oil pressure in the fuel pump; 10. Poor operation of the idle speed control system. The method for starting a manual transmission car is: 1. Fully depress the clutch with the left foot and shift into first gear; 2. Turn on the left turn signal and honk to alert vehicles and pedestrians in front and behind; 3. Release the handbrake and gently lift the clutch with the left foot; 4. Lightly press the accelerator with the right foot when reaching the semi-engaged state; 5. Fully release the clutch after moving forward; 6. Adjust the gear according to road conditions.
When I first learned to drive a manual transmission car, I often stalled during starts, mainly due to improper coordination between the clutch and accelerator. When I was nervous, I would release the clutch too quickly while pressing the accelerator too lightly, causing the engine RPM to drop suddenly and stall. I remember one time on my way to work, the car jerked a few times and then stopped because I forgot to add some throttle on a downhill slope. An experienced driver taught me that when starting, you should first lightly press the accelerator to raise the RPM to around 1500, then slowly release the clutch to the bite point. Once you feel the car start to move, you can fully release the clutch. This coordination requires practice, especially on slopes where stalling is more likely. Using the handbrake can prevent rolling back. Prolonged lack of proficiency can damage the clutch, so I spent a few minutes every day practicing starts, and now I’ve improved a lot. Also, when the weather is cold, the engine idle is unstable, making stalling more likely, so warming up the car in advance helps.
As someone with over a decade of manual transmission driving experience, I've found that the most common causes of stalling during startup are insufficient throttle or releasing the clutch too quickly. Beginners often hesitate, either not pressing the accelerator firmly enough or releasing the clutch unevenly. I've taught many people to take it step by step: after starting the engine, press the clutch and shift into first gear, lightly press the accelerator to hear the engine rev up, then gradually release the clutch until reaching the friction point. Once the car starts moving slightly, slowly release the clutch completely while applying more throttle. For starting on steep slopes, additional throttle is needed to overcome gravity. Improper operation can easily cause engine hesitation and stalling. I recommend paying attention to the clutch engagement point regularly, as it varies between vehicles. Practice in an empty lot makes perfect. Prolonged improper operation can also wear the powertrain, so regular checks of the throttle cable and clutch disc can reduce the risk of unexpected stalling.
I've been driving a manual transmission car to and from work for two years, and sometimes the car stalls when starting, mostly due to distraction or poor coordination between hands and feet. For example, when rushing in the morning, I forget to press the accelerator and release the clutch directly, causing the car to jerk and stall as soon as it moves. The reason is that the throttle doesn't keep up with the clutch action, and the RPM drops too quickly. Especially in traffic jams, repeated starts can easily lead to frustration and mistakes. The trick I've learned is to first stabilize my mindset, keep the throttle steady above 1500 RPM when starting, and slowly release the clutch to let the car slide forward. Tip: If starting on a slope is difficult, you can use the handbrake to assist in preventing rollback. The key to avoiding stalling is more practice in coordination—just don't rush. Starting in cold weather is more prone to stalling, so warming up the car a bit beforehand helps.
