The neutral parking speed fluctuates.

It may be that some wire plugs of the throttle valve are loose or have poor contact, or some sensors of the throttle valve are out of order.

Throttle is called the throat of the engine and is responsible for controlling the amount of air entering the engine.

After stepping on the accelerator pedal, we actually control the throttle opening, not directly control the fuel injection.

After stepping on the accelerator pedal, the throttle opening will increase. At this time, ecu will instruct the fuel injection system to increase the fuel injection quantity, so that the engine speed will rise and the car will accelerate.

If the accelerator is used for a long time, carbon deposition will occur, and the rider needs to clean the accelerator regularly.

After carbon deposits are generated in the throttle, the rider needs to remove the throttle for cleaning, and a professional cleaning agent is needed for cleaning.

You need to reconfigure the computer after cleaning.

If there is carbon deposit on the throttle, ECU will use carbon deposit control logic to control the throttle. After cleaning, ecu can't detect whether there is carbon deposit on the throttle in a short time. At this time, ecu will continue to use the control logic with carbon deposition to control the throttle valve without carbon deposition, which will lead to an increase in engine fuel consumption.

So after cleaning the throttle, be sure to reconfigure the computer.

If some sensors on the throttle valve are damaged, a new throttle valve needs to be replaced. When replacing the throttle, please use the original accessories.
