Answer:
Throttle body
Step-by-step explanation:
The throttle body regulates the flow of fuel to the engine and controls the rate at which the vehicle increases speed.
The throttle body is the part of the air fuel injection system in fuel injected engines that regulates the volume of air circulating into to the engine in response to the pedal feedback of the driver accelerator in the primary. The throttle body is actually located between the intake manifold and the air filter box and is typically connected to or close to the mass airflow sensor.
