When do you need to clean the accelerator for car maintenance?

The purpose of cleaning the throttle valve is to clean the carbon deposit generated on the throttle valve. Generally, the carbon deposit (dirt) produced by the throttle will affect the clearance opening of the throttle. If the throttle clearance is changed, there will be phenomena such as high idle speed, weak acceleration and engine light alarm. This kind of situation usually happens on direct injection vehicles. So you need to go to Shinkansen car maintenance station E for cleaning.
