On flat roads or downhill, the car will not stall, but it will stall automatically when going uphill. Fuel-saving tips for cars: 1. Gear shifting technique: Shift to the appropriate gear according to the speed, and avoid driving at low speeds in high gears for extended periods. 2. Accelerator technique: Press the accelerator gently when starting; stepping on it too hard will only increase fuel consumption and put more burden on the engine. It's best to avoid frequent overtaking and squeezing into gaps. 3. Braking technique: Try to avoid sudden braking, which requires the driver to prepare in advance; gradual braking is best. 4. Tire issues: Ensure the tire pressure is normal, as both underinflation and overinflation will increase fuel consumption, so tire pressure should be checked regularly. 5. Window control: Keep the windows sealed during high-speed driving to reduce wind resistance, which can save fuel.

When I first started learning to drive, I tried staying in second gear without pressing the accelerator, and the car suddenly stalled, which gave me a scare. The instructor explained that it was because the engine speed was too low to maintain idle operation, especially when the car was moving very slowly. I often encounter situations where I'm queuing at a red light in second gear, waiting to move forward. If I forget to give it some gas, the car shudders and stops. Beginners must remember that using the clutch at the biting point with a slight press on the accelerator will prevent any issues. With more practice controlling the coordination between the clutch and accelerator, you'll gradually get used to it. For safety, it's best to practice thoroughly in a parking training area before hitting the road.

As an experienced manual transmission driver, I've noticed that not pressing the accelerator in second gear can easily stall the car, mainly depending on the vehicle speed and engine condition. If the car is still moving but at a low speed, the engine load is small but the RPM is insufficient, the ECU will limit fuel supply causing a stall. My old car is more prone to this, and raising the idle speed a bit actually helps. I recommend gently applying the throttle when starting off, don't try to save that little bit of fuel money. If you do stall, don't panic, just restart the engine, but try to avoid it happening in heavy traffic.

Having driven a manual car for over a decade, I can say that shifting to second gear without pressing the accelerator will likely stall the engine 80% of the time, especially for beginners. The principle is simple: the engine requires a certain RPM to keep running, and when the car is moving but at a slow speed, there's insufficient power. My advice for manual transmission drivers is to always lightly press the accelerator when starting or driving at low speeds. Avoid trying this on slopes or in heavy traffic—safety first.

I've driven various car models, and it's true that the engine can stall in second gear without stepping on the gas, especially in older cars without electronic assistance. The reason is that when the gear is low and the speed is not high, the engine speed drops below idle and automatically stops. This might be better in new cars with idle control, but it can still happen occasionally. For example, when the road is slippery on rainy days and the speed suddenly decreases without stepping on the gas, the car can stall. I recommend developing the habit of frequently using the clutch to adjust at low speeds and not relying on coasting.

A common issue when teaching friends to drive is stalling in second gear without pressing the accelerator, as the engine lacks sufficient power output and the automatic protection mechanism activates at low RPM. This occurs when the speed falls below a certain threshold, similar to improper clutch control during starting. I recommend beginners practice coordinating the clutch and accelerator on flat roads to avoid stalling. Frequent stalling may also increase the load on the starter motor. While not a major issue, it's important to learn and correct this promptly.
