Clean the throttle of your car yourself
The whole process of cleaning the gas door is very simple. The preparation tools are a ring wrench and a Phillips screwdriver. It would be better to have an electric one. My hands have blisters. In addition, it is best to prepare a pair of gloves because the cleaning agent is cold and heart-cooling when it comes to your hands. Of course, you should also prepare a towel to cover the air inlet to prevent dust and debris from entering the engine. Without saying much nonsense, just go straight to the picture above. By the way, after the whole process is over, remember to turn on the power first and not ignite the fire. Wait a while. I don’t know the specific reason. The old driver said that Volkswagen will match it himself, haha, and then observe and compare the idle fuel consumption before and after, and you know it well.
