Honda civic throttle

Because after you clean the throttle, you remove the carbon deposit, and you will get more air when idling. This phenomenon will occur if the parameters controlled by ECU are inconsistent before cleaning, so idling learning is needed after cleaning. The general operation method is: start the car, don't turn on other electricity, raise the engine to about 3000 rpm and keep it for a few minutes. After the water temperature rises, it should be ok before the cooling fan starts. . If it's not enough, go to a 4S shop and ask a professional to do it. . .
