How to Determine if the Throttle Body is Dirty?

[VanMariana]

Methods to determine if the throttle body is dirty: 1. When driving, you may feel a lack of acceleration power, and the acceleration is not as smooth or quick as before, indicating that the throttle body is dirty; 2. If you notice a significant increase in fuel consumption while driving, excluding issues like vehicle overload or prolonged low-speed driving, it suggests the throttle body is dirty; 3. During routine vehicle maintenance, you can inspect the throttle body by opening its entrance to check for dirt. When cleaning the throttle body, it doesn't necessarily need to be disassembled, but the intake sealing area must be thoroughly cleaned. The idle speed motor must be removed for proper cleaning. It's important to reset the throttle opening after cleaning; otherwise, the car's computer, which has memorized the opening with carbon deposits, may cause unstable idling or excessively high engine RPMs if not reset.
