Why Does the Car Always Stall During Hill Start and Stop?

[VanDavid]

Here are the specific reasons for engine stalling during hill starts with vehicle shaking: 1. Insufficient throttle during hill start: When starting on a slope, failure to apply throttle may cause stalling due to insufficient idle speed being unable to propel the vehicle. If the car rolls back, you must first press both brake and clutch pedals, stop the vehicle completely, then restart. 2. Releasing clutch too quickly: During hill start, when slowly releasing the clutch pedal until the vehicle shakes, slightly hold this position to confirm whether the car has forward momentum. Do not continue lifting the clutch pedal to prevent stalling. When the vehicle moves forward, fully release the handbrake with your right hand while gradually applying throttle. 3. Prolonged acceleration in semi-engaged state: Avoid prolonged throttle application while the clutch is partially engaged during startup. 4. Poor throttle-clutch coordination: The correct operation sequence is throttle first, then clutch. When braking, apply brakes before disengaging the clutch. After continuous braking to a certain degree, if the vehicle shakes, it indicates the engine can no longer drive the gears due to braking resistance. At this point, press the clutch to cut off engine power transmission and prevent stalling.
