Spark plugs always getting flooded may be due to an overly rich air-fuel mixture, excessively high oil level, spark plug misfiring, leakage, abnormal ignition from the ignition system, or mechanical failures. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance color to assess its condition. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. If the spark plug has oil stains or deposits, the spark plug itself is not damaged. If the top of the spark plug shows signs of blistering, black streaks, or similar phenomena.

What is the difference between four-wheel drive and two-wheel drive cars?

The differences between four-wheel drive and two-wheel drive cars: 1. Different driving methods: Four-wheel drive maintains all four wheels driving throughout the entire driving process; two-wheel drive only has two wheels as the driving wheels. 2. Different differentials: Four-wheel drive cars require a central differential to adjust the speed difference between the front and rear wheels; two-wheel drive cars have a differential that allows the left and right (or front and rear) driving wheels to rotate at different speeds. Four-wheel drive means that all four wheels of the car can receive driving force, so the engine's power is distributed to all four wheels, making it less likely for the wheels to slip when encountering poor road conditions, and greatly improving the car's off-road capability.
