What are the symptoms of a faulty car fuel injector?
2 Answers
Symptoms of a faulty car fuel injector: 1. Engine shaking: When the car fuel injector is damaged and fuel injection is not smooth, the engine will exhibit symptoms such as operational shaking during operation. 2. Decreased power and increased fuel consumption: As the fuel injector is damaged, the fuel injection volume and pressure cannot be guaranteed, leading to symptoms of decreased vehicle power and increased fuel consumption. 3. Increased tailpipe emissions pollution: The malfunction of the engine fuel injector will inevitably affect the mixing and combustion of the combustible mixture, thereby causing an increase in vehicle tailpipe emissions pollutants. 4. Difficulty starting or even stalling: If the fuel injector is severely damaged, the vehicle may experience difficulty starting, or even sudden stalling during driving. 5. Engine misfire: If the fuel injector of an individual cylinder is severely damaged, the engine is highly likely to experience misfiring, which will cause severe shaking of the engine. 6. Black smoke from the car's tailpipe: As the fuel injector is damaged, the atomization of fuel and its mixing with air cannot be guaranteed, resulting in incomplete combustion of the combustible mixture, which causes symptoms such as black smoke from the vehicle and increased engine carbon deposits.
I've been driving for over 20 years, and when the fuel injectors have issues, the engine shakes particularly violently, especially at idle or low speeds—the whole car rocks back and forth, feeling very rough. I've also noticed difficulty starting the engine, requiring multiple attempts to get it going, and a noticeable lack of power during acceleration, making it hard to climb hills. Fuel consumption increases significantly, jumping from the usual 8 liters per 100 km to 10 liters, which hits the wallet hard. If the problem worsens, the engine warning light will come on, and there may be abnormal exhaust emissions, sometimes with a gasoline smell. Don't delay repairs too long; regular maintenance and cleaning can prevent many of these troubles.
