Wuyang Honda youku 1 10 what is the reason why the throttle is not working?

Wuyang Honda Youku 1 10 is an EFI vehicle. It doesn't have a carburetor, so it can't turn the throttle because the air filter is blocked or the filter is not suitable (although it has been replaced), or the throttle is blocked. Severe starting impact and weak driving may also be caused by large wear and slip of belts and pulleys, or dust in the transmission system and uneven wear of pulleys. Another cause of vibration may be the looseness, large gap or other problems of shock absorber and engine hanger bushing.
