What are the reasons for the engine light on the dashboard?

[LeAlina]

The engine light on the dashboard indicates an engine malfunction, which can be caused by issues such as carbon buildup on the spark plugs or poor fuel quality. Carbon buildup on the spark plugs: After a period of use, the car engine accumulates carbon deposits, which can damage the engine, leading to difficulties in starting, poor acceleration, excessive engine noise, and other symptoms. At the same time, the engine fault light will illuminate. Solution: Soak the spark plugs in a container filled with white vinegar for 2-3 hours, or 4-5 hours for severe cases. Then, use a stiff brush to scrub off the carbon deposits. Clean them with gasoline, let them air dry naturally for some time, and they will be ready for use. Fuel quality issues: Poor or substandard fuel quality. Immediately after refueling, the engine fault light on the dashboard may illuminate, causing severe engine vibrations and increased noise. This is often due to filling up with low-quality fuel at unregulated gas stations. Solution: Switch to higher-quality fuel. If necessary, clean the fuel system.
