Can the throttle coating be repaired?

It can't be repaired. The throttle surface is completely coated with lubricant. After the lubricating oil is cleaned, the throttle will not run smoothly and get stuck, and then there will be failures such as not starting, high idle speed and poor acceleration. This situation can't be repaired, so we can only replace the throttle. There is a special coating on the accelerator, similar to the coating inside the non-stick pan, which has the functions of dust prevention, anti-static and reducing adhesion.
