Will the engine stall if the clutch is fully released in first gear without accelerating?

Releasing the clutch fully in first gear without accelerating will not cause the engine to stall. However, if the clutch is released too quickly, increased resistance without sufficient fuel supply may lead to stalling. Below are some precautions for driving a manual transmission car: When shifting gears, the driver should quickly depress and release the clutch, avoiding the semi-engaged state. Prolonged semi-engagement can cause rapid wear of the clutch disc, reducing its service life. Ensure the clutch is fully depressed when shifting gears. Failing to do so not only makes it difficult to engage the gear accurately but also causes severe damage to the manual transmission over time. Regularly inspect and clean the friction disc and pressure plate in the clutch. Replace the friction disc if cracks, extensive burning, or wear below 3.4 mm thickness are observed. After cleaning or replacing the clutch bearing, apply an appropriate amount of grease.
I've been driving manual transmission cars for almost ten years, and I'm always extra cautious when starting at intersections. If you don't press the accelerator in first gear and simply release the clutch completely, the car will definitely stall, especially when the engine idle speed is low or the road has a slope. Last time, I forgot to give it gas when starting on a slope—the car shook a few times and then stalled. Luckily, the car behind was far enough away, so no accident happened. New drivers should take note: fully releasing the clutch requires the engine to output sufficient torque, and at idle speed, the power isn't enough to support the vehicle's weight. When starting normally, you need to lightly press the accelerator while at the half-clutch point, stabilize the RPM, and then release the clutch. Don't find it troublesome—practice makes perfect, and safety comes first. This situation is more likely to occur in winter when temperatures are low, but with a few more practices, you'll master the timing.
When I first got my driver's license, my instructor always emphasized that starting in first gear required simultaneous handling of the clutch and accelerator. Once during a road test, I got nervous, released the clutch but forgot to press the accelerator, and the car stalled with a 'clunk' right at a crosswalk. The cars behind me honked incessantly, and I panicked, fumbling around. With manual transmission cars, releasing the clutch without giving gas at low-speed starts increases the engine load. If it exceeds the idle capacity, the car stalls immediately. This situation worsens when the car is fully loaded or going uphill. I recommend that beginners practice coordinated movements more: gently release the clutch with your left foot while lightly tapping the accelerator with your right foot to give it some gas. Once you get used to it, you'll make fewer mistakes and avoid that jerky feeling when starting.
The foundation of manual transmission driving lies in power matching. Releasing the clutch in first gear without applying throttle will definitely stall the engine, as the idle torque is insufficient to move the vehicle. You need to coordinate the clutch's friction point with throttle input to raise RPMs for smooth starts. Regularly check if your idle speed is stable during normal driving - low idle or engine aging increases stall risk. When operating, first press the throttle slightly to raise RPMs to around 1500 before releasing the clutch, especially crucial when starting on hills or carrying heavy loads. Mastering this technique protects your transmission and engine, extending their service life.
