How to Clean Throttle Body Carbon Deposits?

[DelHarley]

Methods for cleaning throttle body carbon deposits: 1. Remove the intake hose to expose the throttle body; 2. Disconnect the negative terminal 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 body; 4. Use a polyester cloth or non-woven fabric to wipe clean. For hard-to-reach areas inside the throttle body, use a clip to hold the cloth for cleaning. After cleaning, the throttle body needs to be initialized. Previously, due to sludge blockage, the ECU would automatically adjust the throttle opening to ensure proper air intake. After cleaning, with no more sludge blockage, if the throttle maintains its previous opening, it will result in excessive air intake, causing engine shaking during startup and weak acceleration. The throttle body is a controllable valve that regulates air entering the engine. The air mixes with gasoline in the intake manifold to form a combustible mixture for combustion and power generation. The throttle body connects to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine.
