Understanding Carbon Build Up on the Throttle Body

The throttle body is an essential part of a car's air intake system, responsible for regulating airflow into the engine. Over time, carbon deposits can accumulate on the throttle body, affecting performance and causing issues like rough idling, poor acceleration, stalling, and reduced fuel efficiency. This build-up occurs due to carbon residues from fuel combustion, combined with oil vapors from the engine's PCV system. Regular cleaning and proper maintenance, including using quality fuel and replacing air filters, can help prevent and address carbon build-up, ensuring smoother engine operation.
