What are the symptoms of a faulty fuel injector in an engine?

[StKylie]

Here are the symptoms of a damaged fuel injector in a car: 1. Engine shaking: When fuel injection is not smooth, the engine may experience operational shaking during operation. 2. Decreased power and increased fuel consumption: If the fuel injection volume and pressure cannot be guaranteed, it will lead to reduced vehicle power and increased fuel consumption. 3. Increased exhaust emissions pollution: Faulty engine fuel injectors affect the mixing and combustion of combustible gas mixtures, resulting in increased pollutants in vehicle exhaust emissions. 4. Difficulty starting or even stalling: The vehicle may experience difficulty starting and sudden stalling during driving. 5. Engine misfire: If the fuel injector of a specific cylinder is severely damaged, the engine may misfire, causing severe shaking. 6. Black smoke from the exhaust: Poor fuel atomization and inadequate mixing with air prevent complete combustion of the combustible gas mixture, leading to black smoke from the vehicle and increased engine carbon deposits.
