Car starting RPM is between 1200 and 1500. Causes of car shaking during start-up: 1. The vehicle may shake when the clutch is released to the semi-engaged position; 2. Poor coordination between throttle and clutch; 3. Insufficient engine power; 4. Loose connection between the transmission and chassis; 5. Uneven contact between the clutch pressure plate and friction disc; 6. Dirty throttle body or excessive carbon deposits on the fuel injectors; 7. Worn engine mounts. Hazards of car shaking during start-up: 1. Aggravates carbon buildup in the engine; 2. Causes poor ignition and spark plug misfiring; 3. Accelerates aging of engine components. Solutions for car shaking during start-up: 1. Control the clutch at the optimal engagement point; 2. Replace the pressure plate and friction disc.

I've been driving for over a decade, and I'd say an ideal starting RPM is around 1500, whether it's a manual or automatic transmission. With manual transmissions, you need to gently press the accelerator while finding the balance point with the clutch—too low RPM can cause stalling, while too high wastes fuel or even damages the engine. Normally, when I start the car, the RPM is higher at around 2000 when the engine is cold, then drops back to normal after warming up. In city traffic, starting from a red light should be controlled between 1000-1800 RPM—being too aggressive increases the risk of rear-end collisions or fuel consumption. I usually adjust my pedal pressure by watching the tachometer. Occasionally, starting on a steep slope may require up to 2000 RPM, but overall, maintaining smoothness is most important for both driving safety and engine longevity.

As an automotive enthusiast, I often study engine details. The starting RPM typically falls within the 1000-2000 range. In manual transmission cars, if the clutch isn't fully depressed, the RPM can easily rise above 2500, resulting in an uneven start. Automatic transmissions more automatically control this range, reducing human error. This RPM is greatly influenced by vehicle type; for example, turbocharged cars may start faster. I've driven some older cars where too low RPM causes shaking. To maintain the engine, I recommend avoiding slamming the accelerator. High-RPM starts not only consume more fuel but also accelerate component wear. Regularly checking spark plugs and air filters helps maintain normal values.

As a new driver, I used to feel nervous when starting off right after getting my license. My instructor taught me that starting between 1200-1800 RPM is the safest. In a manual car, releasing the clutch too quickly will stall the engine, while doing it too slowly causes the RPM to surge to around 2000 RPM and lose control, so I practiced more to get the feel. Automatic transmission is simpler—just press the accelerator and the RPM automatically stabilizes around 1500 RPM for a smooth start. If the RPM is too low, say below 1000 RPM, the car might not move, so I keep an eye on the tachometer while practicing. For safety, it's best to start slowly to avoid sudden acceleration and potential accidents—this is very practical for new drivers' growth.

I drive to work every day, and keeping the starting RPM between 1000-1500 is the most fuel-efficient. During rush hour, if the RPM exceeds 1800 when starting from a red light, fuel consumption increases noticeably; maintaining it around 1300 RPM ensures a smooth and economical drive. Automatic transmission cars have a significant advantage in this regard, as the system automatically optimizes the RPM, and I try to minimize sudden acceleration. In congested areas, high starting RPM increases noise and emissions, so I prefer gently pressing the throttle to let the RPM rise gradually. Over time, this habit saves a considerable amount on fuel costs and reduces urban pollution, making it well worth it.

I often deal with car repairs, and the normal starting RPM is around 1500. Exceeding 2000 RPM may indicate a problem. Worn clutch in manual transmissions can cause RPM surges or instability. I've seen cases where the RPM jumps to 2500 during start-up, which requires checking the clutch or electrical system. Automatic transmission system failures can also lead to excessively high RPM. It's advisable to pay attention to noise and vibrations during start-up; if abnormal, professional inspection is needed. Proper clutch can help maintain normal RPM values. To extend component lifespan, avoid high-RPM starts and check idle RPM every six months for peace of mind.
