After cleaning the throttle, reset the throttle opening, otherwise the car computer has memorized the opening when there is carbon deposit.

Matters needing attention in automobile throttle

When cleaning the throttle, spray the throttle cleaning solution to the position with more carbon deposits, wait for 5- 10 minutes, and the carbon deposits will be dissolved by the cleaning solution. At this time, brush it with a clean brush and wipe it with a clean towel.

Before installation, you must wait until the cleaning liquid of the throttle valve is completely dry before installation, otherwise the position sensor will be damaged. In order to speed up the drying of the throttle, oil absorption paper can be used to absorb the oil at some connection positions of the throttle.
