Why did Wuling Light change the throttle assembly and idle at high speed?

First check whether the throttle cable is too tight; If it's not tight, the computer will be adjusted. The idle speed of EFI vehicle is controlled by computer.

After the throttle valve is cleaned by the general EFI vehicle, if the computer is not reset, it is likely to cause a great increase in fuel consumption.

Generally speaking, the simplest reset method is to disconnect the battery cable for more than 30 seconds. I suggest you disconnect 1 min, then reconnect and run again. However, some models cannot be reset in this way, and they must be connected to the maintenance computer through the on-board OBD interface. In this case, you can only go to the 4S shop or garage to repair the computer.
