What Causes Engine Shaking in a New Car?

[OHarrison]

The causes of engine shaking in a new car include an inappropriate air-fuel mixture ratio in the engine compartment, poor fuel quality, and faults in the electronic control system. Here are some additional details: 1. Precautions for driving a new car: Maintain smooth starts, avoid sudden acceleration, and do not let the engine speed get too high. Before starting, ensure the water temperature reaches at least 50 degrees Celsius. Start in a low gear and shift to a higher gear after driving 1 kilometer. Shift gears promptly while driving, avoiding prolonged use of a single gear. Do not use a high gear for low-speed driving or a low gear for high-speed driving. 2. Choose good road conditions: Select smooth roads to minimize excessive vibrations and impacts. Before braking, disengage the clutch first. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.
