How to clean the throttle of the new Jetta?

The following are the specific steps of cleaning: 1. First, remove the throttle: the air filter tube must be removed before removing the throttle. 2. Loosen the upper and lower four screws of the throttle valve, and remove two suction return pipes on the right side of the throttle valve and one pressure pipe on the left side with pliers, totaling three water pipes. Carefully pull off the throttle plug. 3. First, remove the metal card around the black plastic. 4. After removal, gently open the back cover parallel to the throttle by hand to prevent the gear from falling off. 5. Lubricate the motor and gear with original engine oil. 6. Lubricate the rear column of the motor. Finally, put the motor back, fix the gear, plug the washer, cover it, and knock the metal card back and fix it. 7. Then go back and install the throttle.
