Engine idle vibration after maintenance is usually caused by unstable idling, cylinder misfire, or oil dripping onto the oxygen sensor during maintenance. It's necessary to have it rechecked at an auto repair shop. Engine cylinder misfire mainly refers to one or more cylinders not functioning properly, typically manifested as noticeable intermittent exhaust flow, severe shaking of the exhaust pipe, and obvious engine vibration, sometimes accompanied by a sputtering sound. The car engine is the power-generating device of the vehicle, serving as its heart, and determines the car's power, fuel efficiency, stability, and environmental friendliness.

Where to Jack Up a Car When Changing Tires?

When changing tires on a small car, jack it up at the reinforced jacking points located near each wheel, typically marked by notches or indicators on the vehicle's underside. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperature fluctuations during use. Consequently, they must possess high load-bearing capacity, traction performance, and shock absorption. Additionally, tires require excellent wear resistance, flex resistance, low rolling resistance, and minimal heat generation. By application, tires are categorized into: passenger car tires, light truck tires, construction machinery tires, off-road vehicle tires, agricultural and forestry machinery tires, industrial vehicle tires, motorcycle tires, aircraft tires, and special-purpose vehicle tires.

Can You Drive with a Cracked Windshield?

A cracked windshield can still be driven with, but only at low speeds. Driving at high speeds poses significant risks. If there are cracks on the windshield surface, it is recommended that the owner replace it with a new one. During regular use, the front and rear windshields are more prone to damage. When driving at high speeds, flying stones can easily crack the front windshield. Tempered glass is another type of safety glass, widely used in modern vehicles for side and rear windows. Compared to laminated glass, tempered glass gains increased strength through heating and pressurization. When damaged, it shatters into smooth, small crumbs-like particles, reducing the risk of injury from glass fragments.

What is a Vehicle VIN Code?

Vehicle VIN code refers to the Vehicle Identification Number, which is a code that can identify the manufacturer, engine, chassis number, and performance of a vehicle. The VIN code consists of a set of seventeen alphanumeric characters, serving as a unique identifier for the vehicle. Its meaning may vary across different countries or automobile manufacturers. The VIN code is composed of 17 characters, commonly known as the seventeen-digit code. It contains information such as the vehicle manufacturer, year, model, body type and code, engine code, and assembly location. Positions 1-3 (WMI): World Manufacturer Identifier, indicating who produced the vehicle. Positions 4-8 (VDS): Vehicle Descriptor Section, describing the vehicle type, body style, etc. Position 9: Check digit, which uses a specific algorithm to prevent input errors. Position 10: Model year, as designated by the manufacturer, not necessarily the actual production year, but generally within one year of the actual production year. Position 11: Assembly plant. Positions 12-17: Serial number. The functions of a vehicle VIN code include aiding in vehicle record-keeping, facilitating the recording of ownership changes, and preventing theft.

Will there be color difference in paint touch-up at a 4S shop?

The key lies in the repair method - if done correctly, there won't be color difference. Here are three effective methods: 1. Toothpaste for scratch removal: When shiny car paint accidentally gets scratched, don't panic. First clean the scratch with water, then gently rub it repeatedly with a small amount of toothpaste until the scratch fades or disappears, then wipe dry with a damp cloth. This also creates a protective barrier against rust, especially effective for white car paint. 2. Nail polish for scratches: Similar to the toothpaste method, use nail polish matching your car's color. Apply evenly on the scratch and let it dry. The liquid polish fills the scratch and creates a barrier between the metal body and air, preventing oxidation and rust. 3. Touch-up pen: Ideal for small scratches and scuffs. First use ultra-fine sandpaper dipped in water to gently remove rust spots, always sanding in straight lines in one direction. After thorough cleaning, apply a base coat. For fresh scratches, clean and apply base coat directly. While not as effective as professional repair, this method prevents rust expansion for minor or inconspicuous damages.
