Over time, the throttle body can accumulate carbon deposits and other contaminants, which can restrict airflow and cause performance issues like rough idling, stalling, or poor acceleration.
The primary moving component inside the throttle body. It's a flat, round valve that rotates on a shaft. When the throttle plate opens, more air flows into the engine; when it closes, air flow is restricted.
The throttle body is a critical component of a vehicle's air intake system that regulates the amount of air entering the engine. This air is then mixed with fuel and ignited to produce power.
When the driver presses the accelerator pedal, the throttle plate inside the throttle body opens, allowing more air to flow into the engine. The amount of air is directly proportional to how much the throttle plate opens.
