Mai Rui Bao xl2.0t idle speed is high

You mean what should I do if the idle speed of Mai Rui Bao xl2.0t is too high? You can continue to drive, and the idle speed will be restored. If it doesn't return to normal after a period of time, you can go to the service station to check and deal with it.

When the engine runs at high speed for a long time, the carbon deposit inside the engine will be burned off due to high temperature and discharged with exhaust gas. This is why it is often said that it is easy to drive after running high speed.

However, in some engine control systems, the engine control unit can't adapt to the decrease of carbon deposition in individual cylinders immediately. If fuel injection and ignition are carried out according to the previous adaptive values, it will change or be unstable. When the engine is running for a period of time, the control unit will gradually learn new adaptive values and the idle speed will resume.

Other reasons leading to high idle speed of automobiles are as follows:

1, the throttle valve is stuck and not closed properly;

2, idle speed control valve failure;

3, water temperature sensor failure;

4. Air leakage in the air intake system;

5, air conditioning switch, power steering gear pressure switch failure.
