How to effectively remove carbon deposit from throttle?

The effective method for removing carbon deposit in throttle is as follows: 1. Remove the intake throat to expose the throttle valve; 2. Remove the negative electrode of the battery and turn off the ignition switch; 3. Straighten the throttle plate and spray a small amount of carburetor cleaner into the throttle; 4. Scrub with polyester rag or non-woven fabric. Deep in the throttle, you can use a clip to hold a rag and scrub it. After cleaning, the throttle valve should be initialized. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state. If the throttle valve still keeps the previous opening, the engine will shake and accelerate weakly when starting.
