Does the high speed of the car have anything to do with the throttle?

1 has a certain relationship. The opening of the throttle body, whether the throttle body is dirty, the voltage, circuit and position sensor of its components all affect the engine speed (or idle state) to some extent.

2. In addition, the supply of oil circuit, the injection of fuel, whether the internal parts of the engine move normally, and even whether the cylinder pressure is normal will have an impact on it.

3. For the change of vehicle speed, the output of various parameters can be read by the detector first, and the specific problems are analyzed in detail, based on the analysis and test results of the real vehicle.
