How to clean the throttle carbon deposit

The cleaning method of carbon deposit on throttle sensor is as follows: 1. First, remove the intake throat, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, and spray a small amount of "carburetor cleaner" into the throttle valve; 2. Then carefully scrub with polyester rag or high-spin "non-woven fabric". Deep in the throttle, you can hold the rag and scrub it carefully where your hands can't reach it; 3. After cleaning, initialize the throttle according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to keep the air intake in a normal state; 4. There is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, the intake air volume will be too large. As a result, the engine will shake when starting, and the acceleration will be weak, and the engine fault light may light up.
