What are the symptoms of a dirty throttle body?

[LeColin]

The symptoms of a dirty throttle body include: 1. When accelerating, you may feel the throttle is sticky, heavy, and the speed increases slowly. When pressing the throttle at idle, the RPM rises slowly with delayed response, and the speed drops immediately upon releasing the throttle; 2. The precision and smoothness of engine intake are compromised, causing shaking or even stalling at idle, and unsteady acceleration when pressing the throttle. Generally, the cleaning cycle for the throttle body is approximately 20,000 to 30,000 kilometers, but this may vary depending on the vehicle condition and driving habits. The throttle body is a controllable valve that regulates air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. It connects to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine.
