Does the intake tract need cleaning?

[OJason]

The intake tract does need cleaning. Due to various issues such as fuel quality, a significant amount of carbon deposits can accumulate in the intake tract after the engine has been running for a period of time. If the intake tract is not cleaned, it can lead to sluggish acceleration, difficulty starting the car, or even failure to start. Over time, it can also cause wear on the throttle valve and choke plate, resulting in unstable engine idling. Below is some relevant information about the intake tract: 1. There is no fixed interval for cleaning the intake tract; it is generally cleaned along with the intake system, with the specific timing determined by various factors such as driving habits, the vehicle's operating environment, and the control method of the fuel injection system. 2. If the vehicle is primarily driven in urban areas, it is recommended to clean it every 20,000 to 30,000 kilometers. If the car is often driven in environments with poor air quality, the intake tract can get dirty more easily, which over time can affect the engine's air intake and lead to difficulty starting the car. In such cases, it is advisable to clean it earlier than usual.
