What should I pay attention to when cleaning the throttle? Will the cleaning effect be better if it is dismantled? How to remove it? Volkswagen pineapple! !

First buy a bottle of carburetor cleaner, then you have to have a tool to remove the four screws on the throttle, and then the throttle can be removed. If you are an electronic throttle, you can't pull it out, and then the idle speed will be unstable for a while, so you need to match the throttle. If you are a cable puller, unplug all the wires, and then take them down for cleaning, focusing on cleaning the idling motor. If there are two water pipes on the throttle valve, they can also be unplugged. You can find two spark plugs or plugs to block two water pipes to prevent it.
