Public opinion has always been a problem. What should we do?

Regarding your inquiry, this fault is related to idle speed control. First, check whether the idle speed of the engine is normal, and check the carbon deposit on the throttle body and idle valve. If there is carbon deposit, clean it first, and then observe it during the test run to check whether it is necessary to replace the spark plug. When you step on the clutch, the power from the engine to the transmission is cut off, so the idle speed will be more stable. I suggest you change the gearbox oil once. The gearbox oil should be changed once every two years. The internal running resistance of the gearbox will also affect the engine idle speed. The gearbox is difficult to shift gears, and the gear oil needs to be replaced, which has nothing to do with the oil. Too low engine idle speed will affect fuel consumption, and such failures need to be thoroughly inspected. Carbon deposition, failure of electronic control system and untimely maintenance all lead to unstable idle speed.
