Should the throttle valve be removed for washing or not?

If the throttle of the vehicle engine is dirty, it needs to be cleaned in time, otherwise it will affect the service life of the engine. Different ways to clean the throttle valve will have different cleaning effects, so should the throttle valve be removed and washed or not? The cleaning effect of removing the throttle valve is better than that of not removing it, because the cleaning effect is more thorough when removing the throttle valve, and the whole throttle valve can be cleaned without any dead angle. If the throttle valve is not disassembled for cleaning, the cleaning effect inside the throttle valve may be poor, and there will be residual carbon deposit or sludge. There are cable throttle and electronic throttle on the car, and the cable throttle can be directly disassembled and cleaned. The electronic throttle cannot be cleaned at will because it needs to be reset after cleaning. If it is not reset, the vehicle will fluctuate at idle speed, the vehicle will be weak and the exhaust gas will exceed the standard. Car owners try not to clean the throttle themselves. Going to a 4S shop is not only better, but also won't hurt the throttle.
