Cleaning the throttle body helps maintain smooth engine performance by removing carbon deposits that accumulate over time. These deposits can restrict airflow, leading to rough idling, hesitation during acceleration, or poor fuel economy. The process involves disconnecting the air intake hose, using a specialized cleaner, and gently scrubbing the throttle plate and bore with a soft brush. It’s important to avoid spraying cleaner directly on sensors or electrical components. This maintenance is typically recommended every 30,000 to 50,000 miles or when symptoms appear. A clean throttle body ensures precise air control, improving engine responsiveness and efficiency. It’s a straightforward task that can be done at home with basic tools and enhances overall drivability without requiring expensive repairs.
