Is it useful to clean the nozzle and throttle?

Cars need regular maintenance to prolong the service life of auto parts, thus prolonging the service life of cars. Is it useful to clean the nozzle and throttle? It is still very important to clean the nozzle and throttle, because the nozzle and throttle are the core components of the engine, the throttle is responsible for air intake and the nozzle is responsible for oil supply. If there is a problem, it will directly affect the engine. If the nozzle is dirty, it will lead to loud engine noise, insensitive throttle, unsmooth driving and increased fuel consumption. However, if the throttle is dirty, if it is not cleaned for a long time, it will affect the opening and closing of the throttle, and the vehicle will have unstable idle speed, difficult starting and reduced engine power. If the above situation occurs in the vehicle, it is that the throttle and accelerator of the vehicle are dirty and need to be cleaned in time. After cleaning the nozzle and throttle, the car will be brand-new and the vehicle will be used more smoothly. If the nozzle and throttle are not cleaned for a long time, it will not only affect their service life, but also affect the service life of the engine.
