What are the reasons for stalling during hill starts?

[OJudah]

Here are the specific reasons for vehicle shaking and stalling during hill starts: 1. Insufficient throttle during hill start: When starting on an incline, if no throttle is applied, the engine may stall due to insufficient idle speed to move the vehicle. If the car rolls back, you must first press the brake and clutch to stop the vehicle, then restart. 2. Releasing the clutch too quickly: During a hill start, when slowly releasing the clutch pedal until the vehicle shakes, you should hold this position briefly to confirm if the vehicle has forward momentum. Do not continue lifting the clutch pedal to prevent stalling. Once the vehicle moves forward, fully release the handbrake with your right hand and gradually apply throttle. 3. Prolonged throttle application during acceleration: Avoid keeping the throttle pressed for too long while in a semi-engaged clutch state during acceleration. 4. Poor coordination between throttle and clutch: The correct operation sequence is throttle first, then clutch. When braking, brake first, then disengage the clutch. If you press the brake continuously to a certain extent and the vehicle shakes, it indicates that the engine can no longer drive the gears due to braking resistance. At this point, you must press the clutch to cut off the engine's power transmission and prevent stalling.
