Throttle body clean
What is a throttle body clean?
The throttle body can be found in the engine bay, it’s part of the air intake system on fuel injected vehicles.
Air from outside of the vehicle is directed via tubes and flows through the air filter, into the throttle body, where it is then drawn into the intake manifold.
The air then gets mixed with fuel and ignited, creating the combustion required to power the vehicle.
The throttle body controls how much air is drawn into the engine, working in tandem with the driver's accelerator demands.
Inside the throttle body is a plate and valve system that opens and closes in response to acceleration and deceleration. This operation works manually or by sensors.
The ECU determines how much air enters the engine and in turn how much fuel is required to create optimal air-fuel mixture for best combustion.
Since the air-fuel ratio is important in keeping your engine running smoothly, the throttle body needs to be kept clean.
If it gets built up with dirt and grime it could stick open or closed and airflow is impeded.
You might be surprised just how dirty it can get.
