How does Kia Freddy idle at high speed after washing the accelerator?

Hello: Regarding your question, the idle speed of oil collection will increase after cleaning the throttle valve. It may be that the carbon deposit solution enters the throttle shaft when cleaning the carbon deposit, which leads to the blockage between the throttle shaft and the valve base. It is also possible that the throttle is not initialized after cleaning, the throttle cannot completely return to the initial position set by the manufacturer, and the throttle opening is large, resulting in the phenomenon of high idle speed. I hope my answer is helpful to you.
