Which do you want, throttle cleaning or painting?

It is very necessary to clean the throttle and nozzle, because the throttle and nozzle are easy to deposit carbon, which will affect the function of the engine. If the throttle of the car is too dirty, the throttle will leak, the car will feel weak and the fuel consumption will increase. If the nozzle of the car is too dirty, it will lead to the damage of the nozzle, which may lead to the lack of cylinder and engine knocking.
