4S shops can detect odometer tampering. They can check whether the odometer has been tampered with based on repair and maintenance records and professional diagnostic computers. Additionally, for vehicles with automatic transmissions, diagnostic computers can be used to examine the transmission mileage to determine if the odometer has been altered. Here is some additional information: 1. Odometer tampering is common: Odometer tampering is a frequently encountered phenomenon in the used car market. Many used car buyers place significant importance on a vehicle's mileage, which leads to the occurrence of odometer tampering. Tampering with the odometer is relatively simple to accomplish. Even if you don't have professional equipment, you can easily get it done by visiting an auto repair shop for a few dozen dollars in just a few minutes. Most tampering can be done by connecting a diagnostic computer to the OBD interface. However, some vehicle models require specialized diagnostic computers that are specific to the brand, such as German-branded cars, which need their own brand-specific diagnostic tools. 2. Maintenance condition and usage environment are more important: When purchasing a used car, don't focus too much on the vehicle's mileage. What's more important than the mileage is the car's maintenance condition and its usual operating environment. For example, take two cars of the same model, both five years old. One has been used daily in congested urban areas and has traveled 50,000 kilometers. The other has been used primarily on highways and has traveled 150,000 kilometers. Between these two cars, the latter's engine and transmission conditions are likely to be better, and the engine wear is likely to be less than the former's. Therefore, when buying a used car, it's essential to carefully evaluate the vehicle. The mileage will affect the car's price.

Why Can't the Fuel Tank Cap Be Opened?

The fuel tank cap may not pop open due to reasons such as it being stuck or rusted, a damaged fuel tank motor, or the loss of elasticity in the fuel tank cap spring. Below is an analysis of the possible reasons why the fuel tank cap won't open: 1. Rusted fuel tank cap: You can ask a gas station attendant for help; a slight pry or tap, while pressing the fuel tank cap switch, should open it. 2. Damaged fuel tank motor: Most modern vehicles rely on a motor to lock the fuel tank cap, so a faulty motor could be the reason the cap won't open. 3. Loss of elasticity in the fuel tank cap spring: The owner can address this by adding a small spring to the rubber pad on the fuel tank protrusion to increase elasticity between the fuel tank cap and the locking mechanism.

How to Identify Engine Misfire?

Remove the ignition wires one by one. Below are detailed explanations about engine misfire: 1. Definition: Engine misfire refers to insufficient engine power caused by malfunction, where a minority of cylinders among the total number fail to operate. Engine misfire can shorten the lubrication oil usage cycle, easily cause sudden stalling, high fuel consumption, black smoke emission, and power loss. 2. Causes: The main causes of engine misfire originate from the ignition system and fuel injection system. If severe burning occurs on the contacts of the distributor cap in the ignition system, it may cause spark jumping, mostly occurring between corresponding terminals on the cap, resulting in severe idle speed fluctuation and significant power reduction.

How to Determine a Car's Production Date from the Window?

There is a code located at the bottom left or right corner of the car window glass. The production date of the glass can be found in the last or second last row, which consists of a number and several small black dots. Below are some methods to check a car's production date: 1. Check the car's nameplate: The nameplate contains various information, including the engine model, engine displacement, and the car's production date. 2. Inspect the front windshield: The production date of the glass is usually marked in the corner of the front windshield. Unless the glass has been replaced due to damage, this date generally does not differ significantly from the car's overall production date. 3. Look at the VIN (Vehicle Identification Number): Also located below the front windshield, the VIN is a 17-digit code commonly referred to as the chassis number. It is broadly divided into three parts: the World Manufacturer Identifier (positions 1-3), the Vehicle Descriptor Section (positions 4-9), and the Vehicle Identifier Section (positions 10-17). The most important digit to note is the 10th one, which indicates the manufacturing year. If this year is significantly older than the current year, the car may be a long-term stock vehicle. 4. Examine the engine: Normally, the engine compartment should be relatively clean. When starting, the engine should run quickly and smoothly without shaking. You should not feel any vibration when touching the engine, and the sound of the engine running should be barely audible from inside the car.
