Hello! It may be caused by excessive carbon deposition in throttle, idle motor, intake valve, intake pipe and combustion chamber, spark plug and fuel nozzle. Because these carbon deposits will block the idle channel, make the idle motor stuck or out of its adjustment range, resulting in low idle speed, unstable idle speed, oil accumulation and flameout. Also pay attention to check whether there is any leakage in the fuel injector, which leads to the fuel injector still in the fuel supply state after the throttle valve is closed, which leads to the excessive mixture when driving at low speed, which leads to the unstable idle speed after the fuel is turned off, and even more seriously leads to flameout. Then the weak ignition system will also lead to this phenomenon.
