After taking a breath, MG Rui Xing suddenly slowed down, idling unsteadily or flameout.

The reasons for the unstable idle speed of the vehicle after changing gas are: the failure of the electronic control system of the automobile oil-to-gas device.

The solution is: if the automobile oil-to-gas device fails, it is necessary to go to the automobile's 4S shop or repair shop to overhaul or replace it in time to solve the problem of unstable idle speed of the automobile.

There are also reasons that can lead to the fluctuation of automobile idle speed: the idle air hole is blocked, the idle device is not working normally, the spark plugs of individual cylinders are too weak, the seals of individual valves are not tight, the intake manifold leaks air, the ignition time is too early or too late, and the idle speed is not adjusted properly. You need to go to the garage to check the details.
