Throttle Body Cleaner is a specialized chemical solvent spray designed to dissolve the sticky buildup of sludge, gum, and carbon varnish that accumulates on the throttle blade and bore. Over time, exhaust gas recirculation and oil vapors coat the throttle body, preventing the butterfly valve from closing or opening smoothly. This leads to rough idling or stalling. This cleaner is formulated to be safe for coated throttle bodies and sensors, unlike standard carburetor cleaners which might be too harsh for modern sensitive electronic components.
