How often should a car's throttle body be cleaned?

[MadelynAnn]

For most vehicle models, it is appropriate to clean the throttle body every 20,000 to 50,000 kilometers. Below are the benefits of cleaning a car's throttle body: 1. It can effectively clean and unclog the deposits and carbon buildup in the fuel injectors, maintaining the cleanliness of the fuel system. 2. It can clean the exhaust gas recirculation system, reduce emissions, save fuel, and effectively protect the oxygen sensor and catalytic converter. 3. It helps prevent symptoms such as knocking, unstable idling, and poor acceleration caused by deposits and carbon buildup. 4. It can remove carbon deposits from the valve seats, lubricate the valves and valve guides, improve sealing, restore cylinder pressure, and enhance power. 5. It can blow away carbon deposits in the combustion chamber, lubricate the upper area of the cylinders, reduce wear on the piston rings, and extend the engine's lifespan.
