What is the problem of unstable idle speed after cleaning the throttle?

The electronic throttle mainly controls the opening of the throttle according to the air intake required by the engine through the throttle position sensor, so as to adjust the opening of the throttle. So what about the unstable idle speed after cleaning the throttle?

It is common that the idle speed is unstable and the fuel consumption increases after cleaning the throttle. It will take some time for the engine to return to normal, so the owner need not worry.

Under normal circumstances, the throttle valve is cleaned once after driving for about 20,000-30,000 kilometers. It can be cleaned with a special foam cleaner or by removing the throttle valve.

It should be noted that the throttle should not be cleaned frequently, because the surface of the throttle has a dust-proof and antistatic coating. If the cleaning is too frequent or the cleaning solution is not used properly, the coating will be worn and the throttle will be dirtier later.
