What is the purpose of cleaning a car's throttle body?

[StSkylar]

The following are the benefits of cleaning a car's throttle body: 1. Cleaning the throttle body can effectively control the air intake, reducing the engine's load. 2. A dirty throttle body can lead to decreased power, unstable idle speed, and in severe cases, trigger the engine warning light. Regular cleaning of the throttle body can minimize engine issues. Below are the main reasons why a throttle body needs cleaning: 1. As a car is used and mileage increases, carbon deposits inevitably form, and the throttle body is a common location for such buildup. 2. As carbon deposits accumulate, the throttle plate thickens. Since the throttle body operates with high precision, even minor carbon deposits can affect the air intake volume, causing it to deviate from the engine computer's requirements. This results in reduced engine power and increased fuel consumption. 3. A heavily soiled throttle body may cause it to stick, leading to symptoms such as sluggish acceleration, shaking, increased fuel consumption, or even stalling. Therefore, it is essential to clean the throttle body regularly.
