What is the solution for Civic's idle vibration when the air conditioning is on?

Causes and solutions for Civic's idle vibration when the air conditioning is on: 1. Severe engine carbon deposits: The most common cause of car vibration is dirty throttle or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in a lean mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits are saturated with gasoline. After starting, the gasoline adsorbed on the carbon deposits is sucked into the cylinder by the engine's vacuum force for combustion, making the mixture too rich. The engine's combustible mixture alternates between lean and rich, causing idle vibration after a cold start. The solution is to clean the fuel system and check if the idle control valve has carbon deposits, which should be cleaned. 2. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or weak spark plug firing can also lead to such issues. The solution is to check if the spark plugs have excessive carbon deposits and replace them if necessary. 3. Unstable fuel pressure: If you have already cleaned the engine carbon deposits, throttle, replaced the fuel filter, and spark plugs but still experience idle vibration, it is recommended to visit a 4S shop to check the fuel supply pressure and intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can cause body vibration. The solution is to check the fuel pressure and replace components if necessary. 4. Aging engine components: Car vibration can also be related to worn engine mounts. Engine mounts are part of the engine's vibration damping system, responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will transfer to the steering wheel and cabin, causing idle vibration, and they need to be replaced.

How to Check if a Vehicle License is Genuine?

You can identify the authenticity of a vehicle license by its special font or seal, or by the holographic images on the plastic cover. Below are the methods to distinguish a genuine vehicle license: 1. Identify by the special font: The font used on the vehicle license is unique and can only be used by public security departments. It is not available for download online. By observing the special font, you can quickly determine if the license is genuine. The license contains uppercase and lowercase letters, numbers, and special symbols. When opening the license, you can check the font to quickly verify its authenticity. 2. Identify by the seal: Under ultraviolet light, the official seal appears fluorescent red, and the characters may spread over time. 3. Identify by the holographic images on the plastic cover: The plastic cover of the vehicle license features holographic images consisting of patterns like a peace knot, road signs, and vehicles, along with text such as "China CHINA" and "VEHICLE LICENSE (V Gaolaisensi)." The holographic images display different colors when viewed from different angles.

Will 4S shops perform internal rust prevention after sheet metal repair?

Generally not. Under normal circumstances, the protection of electrophoretic paint is sufficient, so they often skip additional protective measures. Nowadays, larger 4S shops will apply wax treatment, which involves spraying a layer of wax inside the sheet metal to compensate for any deficiencies in the electrophoretic coating. Here are some precautions to take after spray painting: 1. Pay attention to cleaning after painting: Try not to use water other than soft water, including hot water, alkaline water, and water with high hardness. These components can damage the paint. If hard water is used to clean the vehicle, it may leave marks on the paint surface after drying. 2. Do not expose the car to strong sunlight: This can affect the car's paint surface, accelerating its aging. 3. Do not use high-pressure water flow to rinse the car body: If there is hard dirt on the car, it should be soaked with water first and then rinsed. Pay attention to the water flow method; dispersed water flow should be used for cleaning, as excessive water pressure can also damage the car's paint surface. 4. Use detergents: If there are stubborn stains on the car body, detergents with different properties should be selected. If there are dead insects or other biological juices on the car body, they should first be soaked with soapy water; then cleaned with a water-soaked sponge.

What is the weight of a sedan?

Generally, the load capacity of a family sedan ranges from 375 to 400 kg. The actual load capacity should strictly follow the weight indicated on the nameplate attached by the manufacturer at the time of production. The national standard sets the load capacity at 375 kg, meaning that the manufactured vehicle's load capacity cannot exceed this limit. Calculating based on the minimum standard of 375 kg, the car can accommodate four people weighing 150 pounds each and still have space for nearly 100 pounds of additional items (including fuel tank, spare tire, onboard tools, fire extinguisher, etc.). Below are the damages caused by overloading to the vehicle: 1. Reduced braking performance and increased non-safe zone distance. Many factors affect a car's braking distance, among which changes in vehicle load directly impact the length of the braking distance. Overloaded vehicles, due to increased inertia, require a longer braking distance. The extension of the non-safe zone distance can easily lead to traffic accidents; 2. Shortened lifespan of leaf springs and reduced vehicle passability. Overloading causes excessive stress on the leaf springs, leading to continuous bouncing during driving, which shortens their lifespan. Additionally, the excessive load causes the vehicle to sink overall, reducing the ground clearance and diminishing the car's ability to pass through certain areas; 3. Accelerated tire wear and deformation. When a car is overloaded, the tires bear excessive weight, leading to deformation. Increased friction also results in a shortened tire lifespan.

How to Distinguish Start-Stop Batteries?

Start-stop batteries can be identified by the following methods: 1. Appearance differentiation: Start-stop batteries have dedicated markings on their appearance, while ordinary batteries do not have such specific symbols. If the original battery is labeled with any of the following: ST, N55, Q85, S95, ISS, EFB, AGM, VRLA-BATTERY, start/stop, or idle stop system vehicle, it is a start-stop battery. 2. Weight differentiation: Start-stop batteries are heavier than ordinary batteries. When shaken, there is no sound of liquid inside. Installing ordinary lead-acid batteries in vehicles equipped with start-stop systems will shorten the battery's lifespan and introduce uncertain safety hazards during driving.

What Happens When Car RPM Is Too High?

The following are the impacts of excessively high car RPM: 1. Engine: Prolonged high RPM can place a significant burden on the engine due to overheating. If the vehicle outputs excessive torque at 3500-4000 RPM, driving or shifting gears at this RPM for extended periods can cause excessive torque on various components (engine, transmission, tires, etc.), leading to reduced lifespan. 2. Fuel Consumption: This results in increased fuel consumption, and higher speeds also reduce safety. When shifting gears at 3500-4000 RPM, the vehicle may experience a slight lurch forward; appropriately lowering the shift RPM can achieve optimal driving economy. Additional Information: 1. Rated Condition: The operating condition of the engine at rated power and rated RPM is referred to as the rated condition. 2. Rated Power: Rated power is the maximum effective power usage limit determined based on the engine's intended application.
