What Causes Car Shaking and Stalling During Hill Start?

[Bobby]

Here are the specific reasons for car shaking and stalling during hill start: 1. Insufficient throttle during hill start: When starting on a slope, insufficient throttle may cause the engine idle speed to be too low to propel the vehicle, resulting in stalling. If the car rolls backward, you should first press the brake and clutch to stop the vehicle, then restart. 2. Releasing clutch too quickly: During hill start, when slowly releasing the clutch pedal with your left foot until the vehicle shakes, you should pause briefly at this position to confirm whether the vehicle has forward momentum. Avoid further lifting the clutch pedal to prevent stalling. When the vehicle moves forward, fully release the handbrake with your right hand and gently apply throttle. 3. Prolonged throttle application during acceleration: Avoid keeping the throttle pressed for too long while in semi-clutch state during acceleration. 4. Poor coordination between throttle and clutch: The correct operation sequence is throttle first, then clutch. When braking, apply brake before clutch. After continuous braking to a certain extent, the car body will shake, indicating that the engine can no longer drive the gears due to braking resistance. At this point, you should press the clutch to cut off the engine's power transmission, thereby avoiding stalling.
