If you experience unstable idling, difficulty starting the engine, or the engine starts but the vehicle doesn't move, accompanied by noticeable vibrations, it's time to clean the throttle body. The function of the throttle body: The throttle body is a controllable valve that regulates the air entering the engine, located between the air filter and the intake manifold.
