How to deal with the low idle speed of Camry after power failure?

There are many reasons for the low idle speed of the engine after power failure, such as the problem of idle speed control valve, throttle blockage, air filter blockage, insufficient injection pressure and so on. The idle speed of the engine is controlled by the throttle. When the engine is idling, the throttle will keep a small opening. At this time, if there is carbon deposit in the throttle or air intake, the air intake will be too low, resulting in low idle speed of the engine or even flameout. The following is the introduction of engine protective agent: 1. Introduction of engine protective agent: Engine protective agent, also known as engine anti-wear protective agent, is a maintenance agent, which can effectively reduce the wear or corrosion of engine parts, inhibit the formation of colloid, sludge and other deposits, form a protective layer with high compressive strength and good wear resistance on the metal surface, and prevent engine oil from oxidation, thickening and acidification, thus protecting engine parts and prolonging engine life. 2. Function of engine protective agent: The function of engine protective agent includes anti-wear, lubrication, noise reduction, improving engine power and fuel saving, preventing engine oil from burning and cleaning up carbon deposits.
