Is there a difference between painting at a 4S shop and outside?

The painting quality at a 4S shop is relatively more reliable. Vehicles processed at a 4S shop undergo mutual quality inspections between various processes and a final inspection by a quality inspector before delivery. The manufacturer also has a relatively complete service supervision system to protect customer rights. In contrast, some paint and beauty shops lack a sound supervision and service system, which may lead to difficulties in safeguarding rights later. Precautions after car painting: Pay attention to cleaning after painting: Try not to use water other than soft water for cleaning, including hot water, alkaline water, and water with high hardness, as these components can damage the paint. If hard water is used to clean the vehicle, it may leave marks on the car's paint surface after drying. Avoid exposure to sunlight: Do not expose the car to strong sunlight, and do not wash the car immediately after the engine has cooled down, as this can also affect the car's paint surface and accelerate the aging of the paint.

What is the reason for engine shaking at idle but not when accelerating?

The reasons for engine shaking at idle but not when accelerating are: 1. Changes in fuel injection volume; 2. Malfunction in the fuel pump pressure regulator or sensors causing faulty fuel injection correction signals; 3. Cracked vacuum booster pipe; 4. Carbon buildup or dirt on the throttle body, or incorrect positioning of the throttle position sensor. The connection points between the engine and the frame are equipped with engine mounts, which absorb vibrations generated during engine operation. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. Idling results in low engine speed, which can propel the vehicle forward under light load conditions.
