What are the symptoms of a dirty fuel injector?

[SanValentina]

Symptoms of a dirty fuel injector: 1. The throttle response becomes less sensitive, and acceleration is not as smooth as before; 2. The engine noise increases, especially noticeable at low gears and low RPMs; 3. Driving becomes less smooth, the car feels less powerful, and there is a lag when pressing the accelerator. In neutral, the tachometer needle rises slowly; 4. Idling becomes rough, especially noticeable when starting; 5. Fuel consumption increases; 6. The car's emissions exceed standards; 7. In severe cases, it can damage the engine and reduce its lifespan. The fuel injector is one of the key components of an electronic fuel injection engine, designed to atomize gasoline for better combustion. However, due to various factors, carbon deposits can form on the fuel injector. For example, gasoline itself contains impurities that can form sludge-like deposits over time. Additionally, unstable components in gasoline can react at certain temperatures, forming sticky substances like gum and resin. Therefore, it is necessary to clean the fuel injector regularly, typically every 40,000 to 60,000 kilometers.
