Porsche sports cars have a high speed every time they are ignited.

Because the vehicle starts to cool down, the engine computer board will control the increase of fuel injection and throttle opening in order to make the vehicle start smoothly. So the degree of haste will be higher. After a few minutes of normal idle speed, the vehicle will drop to normal idle speed.

If the idle speed of the vehicle has been high since the start, it is likely that the throttle of the vehicle is too dirty or the engine is faulty, and it needs to be checked in a repair shop.
