16 changan Ford mondeo's idle speed is unstable after washing the throttle.

/kloc-changan Ford mondeo washed the throttle in 0/6 years, and the idle speed was unstable, mostly because the throttle opening was not reset.

Because of the long-term carbon deposition, the throttle valve is squeezed by carbon deposition, and the opening of the throttle valve is also expanded. After we clean the throttle, if we don't reset it, the throttle opening will be the same as before carbon deposition, which will lead to the expansion of air intake and supply, and in serious cases, idling jitter and fuel consumption will increase.

Before cleaning the accelerator, pull out the negative electrode of the battery or after cleaning, turn the key to the on position for a few minutes to turn it off, then turn it to the ON position, step on the accelerator completely without stopping, and then restart the car.
