Should Regal match the throttle after cleaning?

After the throttle valve is cleaned, it must be re-matched with a special driving computer. This is because the throttle valve is opened wider due to carbon deposition. After cleaning, if it is not recovered, the throttle opening will remain in the state before carbon deposition, and there will be phenomena such as increased air intake, unstable engine idle speed, too fast speed and increased fuel consumption. Throttle pollution impact: 1. First, it affects the engine power. The throttle is too dirty, and the throttle moves slowly. Many impurities are entrained in the air entering the engine, which affects the normal combustion of gasoline and reduces the working power of the engine. In severe cases, the idle speed is unstable, it is difficult to start and the power is reduced. 2. Finally, it should be noted that after cleaning the throttle, the opening of the throttle must be reset. Otherwise, the car computer has long remembered the opening when carbon is deposited. If it is not reset, the engine will have unstable idle speed and high speed, which is worse than before cleaning; 3. The reset mode varies with the vehicle model, so it will not be introduced here. If the owner is worried, it is best to go to a professional repair shop or 4s shop for repair.
