What to Do If the Car's Shock Absorber Is Leaking Oil?

What Causes the Car Body to Shake When Shifting Gears?

The reasons for the car body shaking when shifting gears are as follows: Dirty Throttle or Excessive Carbon Deposits on the Fuel Injector: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold-start fuel injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start the engine. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, causing the air-fuel mixture to become too rich. The fluctuating air-fuel mixture—sometimes too lean, sometimes too rich—leads to unstable idling and shaking after a cold start. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits will significantly affect whether the cold start proceeds smoothly. Check the Spark Plugs: For ignition system issues, inspect the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or inadequate spark plug firing can also cause such symptoms. 4S Shop Inspection: Unstable Fuel Pressure: If you have already cleaned the engine carbon deposits, cleaned the throttle, replaced the gaskets and spark plugs, but still notice the car body shaking during idling, it is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensors are functioning normally.

Why Can a New Car Only Run at 80?

Because the car needs a break-in period initially. If the speed is too high, the car's components may not be properly broken in, which could lead to potential hazards. In short, 80 mph is not too slow; after about a month of break-in, you can increase the speed. Warm up the car before starting during the break-in period: For fuel-injected cars, turn the key to the second position and wait for 5-10 seconds before starting. Avoid overloading: Running a new car at full load can damage the components. Therefore, within the first 1,000 kilometers, domestic cars should not exceed 75-80% of the rated load, and imported cars should not exceed 90% of the rated load. Avoid long-distance trips: Taking a new car on long trips will cause the engine to run continuously for extended periods, leading to increased wear on the components.

Will the car move when in D gear without pressing the brake?

Without pressing the brake, the car will move slowly or may stop. On a slope, it might even roll backward. At traffic lights, there's no need to shift gears; just keep it in D and press the brake. The same applies when moving slowly in traffic jams. For prolonged traffic jams, you can shift to N or P, or turn off the engine to save fuel. Introduction to D Gear: D gear is the most common gear in automatic transmission vehicles, usually located in the middle-rear position of the gear shift console, behind the N gear. Its purpose is to enable the car to automatically select the appropriate gear while moving forward. Purpose of D Gear: D gear is the most widely used forward gear in automatic transmission vehicles. Its main function is to allow the transmission's computer and accompanying mechanical structures to automatically select the appropriate gear in real-time while the vehicle is moving forward, eliminating the need for manual gear shifting. This greatly frees the driver's hands and feet, enhancing driving convenience, ease, and comfort.

Is it allowed to overtake on urban expressways?

Overtaking from the right lane is permitted. The commonly mentioned left-side overtaking should be applied when driving on roads without lane dividers. When lanes are clearly divided, driving normally within your own lane without speeding is certainly acceptable. Introduction to Overtaking: Overtaking refers to the process where a following vehicle changes lanes to the rear side of the preceding vehicle, passes it, and then returns to the original lane. The lane typically used for overtaking is the inner lane, which is closer to the center of the road and farther from the shoulder. Overtaking Precautions: In regions where driving is on the right, the overtaking lane is the leftmost lane; in regions where driving is on the left, the overtaking lane is the rightmost lane. Overtaking is an inherently risky maneuver that is sometimes unavoidable while driving. It requires proficient skills and techniques, as well as strict adherence to traffic regulations, to prevent accidents and incidents.

How many kilometers can Goodyear EfficientGrip Performance II run?

Goodyear EfficientGrip Performance II can run up to 30,000 kilometers. Introduction to Goodyear EfficientGrip Performance II: The EfficientGrip Performance II tire is a tire specifically designed for luxury sedans, offering quiet comfort and excellent wet braking performance. With its innovative tread and carcass design, advanced shock-absorbing carcass, and silica compound formula, it provides drivers with a quiet and comfortable driving experience. Design features of Goodyear EfficientGrip Performance II: The closed shoulder design effectively blocks the transmission of sound waves, thereby reducing both external and internal perceived noise levels; the uniform distribution of tread blocks ensures a softer contact with the ground, reducing impact noise and preventing the resonance transmission of sound frequencies; the vertical tread block edge design minimizes rigid deformation of the blocks, reducing block-to-block movement, and effectively avoids noise caused by uneven tread wear after long-term use; the shock-absorbing carcass structure is designed for smooth driving.

What Are the Basic Requirements for Correct Driving Posture?

When driving, it is required to keep the body straight, look ahead, and stay fully focused. Pre-driving precautions: Sit upright, adjust the seat back to a suitable position so that the back is completely in contact with the seat back; adjust the seat position so that with slightly bent legs, all pedals can be operated effectively; correctly adjust the seat headrest; properly fasten the seat belt. Driving precautions: Front-seat passengers should adjust the seat to maintain an appropriate distance from the dashboard, which provides the most effective safety protection when the airbag is deployed; front-seat passengers should adjust the seat back to a suitable position so that the back is completely in contact with the seat back; feet should be placed on the floor; when carrying children, appropriate child safety seats must be used as required to protect the children.
