[VanColin]

Methods to determine if the throttle body is dirty include: 1. The vehicle idles with some shaking, especially when just starting the engine, the shaking is more noticeable, indicating a dirty throttle body; 2. While driving, you may feel a lack of acceleration power, not as smooth and quick as before; 3. During routine vehicle maintenance, you can inspect the throttle body by opening its inlet for a detailed check. When cleaning the throttle body, it may not need to be disassembled, but it is essential to thoroughly clean the intake sealing parts. The idle speed motor must be removed to be cleaned properly. There are pros and cons to both disassembling and non-disassembling methods for cleaning the fuel injectors. Generally, service stations recommend non-disassembling cleaning to avoid unnecessary waste.
