Li Xia n3+ Release the throttle, what should I do if the speed is unstable?

As for the problem of unstable idle speed of oil collection you asked, as no existing vehicle has been seen, it may be caused by excessive carbon deposition in throttle valve, idle motor, intake valve, intake pipe and combustion chamber, spark plug and fuel nozzle. It is estimated that the main problem is excessive carbon deposition in the throttle. Because these carbon deposits will block the idle channel, the idle motor will be stuck or beyond its adjustment range, resulting in low idle speed, unstable idle speed, oil collection 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. I hope my answer is helpful to you.
