In 2007, when the old Prima cold car started, a lot of energy came out at high idle speed. How to fix it?

It is normal for a cold car to start at high idle speed. Let the engine enter the normal working environment as soon as possible after starting in the cold car state, so when starting in the cold car, the engine will automatically inject more fuel. By burning more fuel than the normal idle speed, the water temperature of the engine can be quickly raised and the engine can quickly enter a suitable temperature. The rotating speed is generally 950 to 1300 rpm. When the engine temperature rises to a certain value, the idle speed will decrease to the normal value. The cold start of a car refers to when the engine water temperature is low. Generally, cars don't start for a long time, such as after parking at night.
