What are the steps to clean the throttle body?

The steps to clean the throttle body are as follows: 1. Remove the engine cover and detach the intake pipe connected to the throttle body, where you will find a significant amount of oil sludge and carbon deposits. Note that the metal clamp should be tightened with screws. 2. Remove the throttle cable, then disconnect the three sets of wiring connected to the throttle position sensor, idle motor, and intake manifold absolute pressure sensor. 3. Use a hex wrench to remove these three electronic components, and you will notice oil sludge adhering to the telescopic rod head of the idle motor. 4. Use carburetor cleaner to clean the oil sludge inside the throttle body, especially around the throttle valve. Excessive sludge can fill the gaps around the throttle valve inside the throttle body. Then, spray the telescopic rod of the idle motor with carburetor cleaner and wipe off the sludge with a cloth until the metal shines. Also, clean the exposed oil sludge on the motor shaft. 5. After thorough cleaning, carefully reinstall the three electronic components. Use the remaining cleaner to rinse off any external oil stains and reinstall the throttle body as it was. Remember to reconnect the wiring for the three electronic components on the throttle body; otherwise, the computer will automatically trigger an alarm when the key is turned during the final inspection.
