Didn't the car have high idle speed during cold start?

The throttle is out of order Users only need to clean the throttle.

Too dirty throttle will lead to throttle opening error, throttle sensitivity will be reduced, and it may not be closed well at idle speed, resulting in abnormal idle speed. In addition, the throttle failure will also affect the engine's power, acceleration performance and fuel consumption, and even lead to difficulties in starting in serious cases.

Because the engine needs to enter the normal working environment as soon as possible after the car is started in a cold state, when the car is started, the engine computer will automatically inject more fuel, and by burning more fuel than the normal idle speed, the water temperature of the engine will rise rapidly, so that the engine can quickly enter the appropriate temperature. The main performance is that when the car is cold, the idle speed of the engine will be relatively high, generally at 950- 1300 rpm. When the engine temperature rises to a certain value, the idle speed will drop to the normal value.
