The throttle body is a part of the air intake system which controls the flow of air in an engine. Your vehicle's throttle body is comprised of numerous parts, which are the throttle plate, the housing, and the shaft. The throttle body is an integral piece of the overall throttle system and your vehicle's air intake system, which regulates the acceleration and speed of the car's engine. Your throttle body works after you press down on the car's gas pedal.
When you press the gas pedal, you are really stepping on the air - engaging the gas pedal opens a valve in the throttle plate inside the throttle body, increasing the level of airflow. Low or high idling, a noticeable drop in fuel efficiency, a sputtering or stalling engine and sluggish acceleration are all important potential signs that your auto's throttle body may be in trouble.
Responsible for providing the engine with the exact amount of air it needs to feed the combustion process, this part is a crucial piece of the air intake system in fuel injection vehicles.

In general, a throttle is simply some sort of mechanism used to control the movement of fluid or air by either constricting or blocking its flow. In combustion automotive engines the throttle is specifically used to manage the flow of air into the engine.
Maintaining just the right ratio of air and fuel within the engine is essential to gaining the greatest possible efficiency and performance. In a carbureted engine the throttle is typically housed within the carburetor itself.
In a fuel injected engine it sits at the entrance of the intake manifold or is placed in the throttle body. The cost of a replacement throttle body will vary greatly depending on the make and model of your car, as well as whether you are looking for a performance part. Most of the replacement throttles on PartGeek.
Your car's accelerator pedal could also be called a "throttle pedal". As you press down on the accelerator an electrical sensor known as the throttle position sensor registers the precise location of the pedal, from not pressed at all to pressed all the way down.
When the car is running, this data is constantly being relayed to the onboard computer. Also called the Engine Control Unit ECU , this computer in turn controls the amount of fuel that the injection system needs to provide the expected power output, as well as the amount of air that is allowed to flow via the throttle body through the intake manifold.
When the accelerator pedal is pressed, a rotating plate within the throttle body passageway opens or closes to provide more or less air to the engine. In order for your car to run its best, it is crucial to maintain the precise ratio of air and fuel within the running engine at any given time. That means that a faulty air intake system can lead to potentially serious performance issues. Poor fuel efficiency, weak acceleration or an unusually high or low idle could all be signs of a faulty throttle body.
Common issues include electrical shorts or wire breakage, which can prevent good communication between the throttle body sensor and the ECU. Additionally, leaking or poorly-fitted vacuum seals can compromise the internal system pressures needed to effective push air and fuel through the system. Finally, the buildup of carbon or other unwanted deposits can disrupt the precise flow or air, throwing off the delicate ratio needed for efficient internal combustion.
This fit great. You can choose to use the supplied bolts or keep the stock ones. By itself, don't expect a change in performance. If you are buying an aftermarket intake, keep in mind this is larger than stock. I found this brand new Hella Throttle Body for my old Saab Viggen substantially cheaper than any where else.
