Is Cleaning the Throttle Body Useful?

Cleaning the throttle body is useful, and the cleaning method is as follows: 1. Turn off the ignition switch and remove the negative terminal of the battery; 2. Remove the throttle cable, intake hose, and the screws fixing the throttle body in sequence; 3. Use a cleaning agent to clean the throttle body, and use a cotton swab to wipe areas that are hard to reach. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to produce power. Symptoms of a damaged throttle body include: 1. Unstable engine idle speed, with high idle speed persisting; 2. Difficulty in starting the engine; 3. Insufficient engine power, poor acceleration performance, and unstable operation; 4. Black smoke from the car's exhaust pipe; 5. The engine fault light is on.
Cleaning the throttle body is definitely useful. I've been driving for over a decade and encountered many similar situations. When too much carbon builds up in the throttle body, preventing air from entering the engine, the car may experience issues like unstable idling and unresponsive acceleration. After cleaning, the engine immediately runs smoother with less vibration and more responsive acceleration. I remember one time when my old car had unstable idling, and after cleaning, the fuel consumption even decreased slightly. However, don't clean it too frequently; just check it every 20,000 to 30,000 kilometers. Also, choose a mild cleaning agent to avoid damaging electronic components. In short, targeted cleaning has many benefits, but don't waste money if there are no symptoms.
