How often should the throttle body of a new car be cleaned?

[MacChristian]

It is recommended to clean the throttle body of a new car every 30,000 kilometers. If the driving environment is harsh, the cleaning interval should be shortened. Method for cleaning the throttle body: If there is a plastic heat shield on the engine, remove it. Then disconnect the air ducts around the throttle body and note their positions. Typically, the side of the throttle body closer to the combustion chamber tends to be dirtier, with black carbon deposits being the main area to clean. Special cleaning solutions or carburetor cleaners can be used, but these chemicals can be harmful to humans, so wear gloves and a mask during cleaning. Spray the cleaner onto the areas with heavy carbon deposits on the throttle body and wait 5-10 minutes. Once the carbon deposits dissolve, wipe them off with a cloth. After cleaning, reinstall the throttle body in its original position and reconnect all air ducts.
