Why Does the Car Engine Light Flash?

[BentleyAnn]

Reasons for the car engine light flashing: 1. Excessive carbon deposits: Too much carbon buildup in the throttle or inside the engine. 2. Imbalanced air-fuel mixture: Malfunction of the oxygen sensor leading to an imbalanced air-fuel mixture. This phenomenon is common if the car is frequently driven at low speeds in urban areas. 3. Fuel injector leakage: Leakage in the fuel injector causes it to continue supplying fuel even after the throttle is released, resulting in an overly rich mixture at low speeds and unstable idle after releasing the throttle. In severe cases, the engine may stall directly. 4. Oxygen sensor poisoning: Using low-quality gasoline with excessive metal content can poison the oxygen sensor. The solution is to switch to a different gas station.
