Benefits and cleaning methods of cleaning throttle valve

Recently, many car owners in Chengdu have asked Wang Chang about the benefits of cleaning the throttle and how to clean it. Today, Wang Chang and Bian Xiao consulted some experts in the automobile maintenance industry with these questions, and collected a large number of cleaning methods for Li Xia's automobile throttle, sorting them out for all car owners who need to clean the throttle. If the idle speed is high and the idle motor has been replaced, it should be further checked according to the following three points: 1. Check the engine vacuum tube for air leakage, and if it is determined to be air leakage, replace the vacuum tube. 2. Check whether the engine fault light on the instrument panel flashes. If engine failure is found, you should immediately go to the 4S shop for computer inspection to see which parts have problems that lead to unstable idle speed, including sensor failure, engine combustion failure, valve position sensor failure and so on. 3. Check whether the throttle valve is dirty. Whether there is carbon deposit in throttle and idle Madari. Unclean throttle will lead to lax throttle closing or stagnation of idle stepper motor, which will lead to excessive engine idle speed.
