Idle speed is stable without jitter, 5w km. Do you need to clean the throttle?

Hello, if you haven't done it, you'd better clean it. If the throttle is dirty, it will lead to unstable idling and jitter. Cleaning the throttle can improve the working condition of the engine and solve the problems such as jitter and fuel consumption. The throttle valve is located at the engine intake. The so-called dirty throttle means that a layer of sludge is attached to the throttle itself and the inner wall of the nearby airway. The throttle is controlled by ECU. The ECU will adjust the throttle opening according to the intake demand of the engine.
