In fuel injected engines, a throttle body is the part of the air intake system that controls the amount of air that flows into an engine’s combustion chamber. It consists of a housing unit that contains a throttle plate also called butterfly valve that rotates on a shaft.

When the accelerator is pushed down, the throttle plate opens and allows air into the engine. When the accelerator is released, the throttle plate closes and effectively chokes off air flow into the combustion chamber. This process effectively controls the speed of the engine and ultimately, the speed of the vehicle. The throttle body is usually located between the air filter box and the intake manifold.

Problems with the throttle body assembly result in the throttle letting in too much or too little air. Too much air causes engine surging and rough idling. Too little air causes slow or uneven acceleration and sometimes stalling. Throttle body problems can also decrease fuel mileage.
