Li Xia automobile maintenance

You can choose to take the vehicle diagnostic instrument to the maintenance point to check the cause of high idle speed.

You can also try, first put out the fire in the car, then turn the key door to the ignition position, wait until all the instrument lights go out, then take a taxi, wait until the water temperature is hot, then see if the idle speed is still high, and see what the water temperature is!

Or go to a few maintenance points. I really want to remember that a small part of the engine is broken (vacuum valve). I forgot.
