To fix the situation, you can get your car’s throttle body serviced and the engine vibration will go away. **2.Check Engine Light** As soon as the car’s onboard computer detects a problem with the throttle body, it will cause the check engine light to illuminate. **3.Poor Engine Performance** The engine requires both adequate air and fuel supply to perform effectively. If the engine is not receiving proper air supply due to a damaged throttle body, the engine will suffer and as a result, the driver would experience a drop in the performance. **4.Drop in Mileage and Acceleration** A dirty or damaged throttle body reduces the overall performance of the car. If you notice that your car is not accelerating properly or there is a drop in the fuel economy, it is most likely due to a faulty throttle body. According to the electric signal and outside variables, the ECU calculates the required intake air volume (in form of the opening of the butterfly valve), the corresponding fuel injection volume, and the optimal ignition time, that achieves the optimum efficiency and performance. **Precautions for throttle body cleaning：** During cleaning, focus on cleaning the throttle body cavity, throttle and throttle shaft until there is no dirt. After cleaning, repeatedly pull the throttle control mechanism to check whether the throttle switch is free. In addition, clean the joint surface between the air inlet and the throttle body. Remove the sealing rubber ring before cleaning to prevent corrosion. When cleaning the throttle valve, the integrated circuit cover must face up to avoid damaging its components.
