How Often Should the Fuel Injector and Throttle Body Be Cleaned?

[DeCarter]

Generally, it is suitable to clean the throttle body every 20,000 kilometers; the fuel injector does not need cleaning under normal circumstances, or it can be cleaned every 80,000 kilometers. Below is a detailed explanation of cleaning the fuel injector and throttle body: 1. Fuel Injector: The fuel injector is not a wear-and-tear component. As long as the car idles and starts normally, there is no need to clean it. Using fuel from reputable gas stations usually prevents damage. If it fails, it should be replaced directly. 2. Throttle Body: It is generally suitable to clean the throttle body every 20,000 kilometers. Nowadays, most car models use electronic throttle, while only a few older or low-end cars still use cable throttle. These two types differ in structure. The cable throttle is equipped with an idle motor. For inexperienced car owners, it is recommended not to clean the throttle body themselves, as this may lead to increased valve clearance, higher fuel consumption, and elevated idle speed.
