The new Sail 1.2 electronic throttle sometimes fails to fill.

Let me help you answer your question. The electronic throttle can't be filled with oil, which may be caused by the uncleanness of the electronic throttle. Need to clean the throttle. Then match it. The electronic throttle transmits electrical signals. If the throttle is too dirty, the signal transmission between the pedal and the throttle is blocked.

I hope it helps you. Forgot to adopt.
