If you’re having problems with accelerating, uneven idling, or stalling out, you could have an issue with your throttle body. The throttle body controls the amount of air that your engine receives and affects the way your engine runs. Because you can’t operate your vehicle safely with a dirty or failing throttle body, it is urgent that you fix the issue.
Expect to pay a professional between $225 and 290 to clean a throttle body and between $500 and 600 to replace a throttle body.
Review this short guide provided by car insurance broker app Jerry, which will give you a brief overview of your engine’s throttle body.
The exact cost varies between different Bentley models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is a throttle body?

Combustible engines require not only fuel but air to operate. The amount of air that enters the engine is controlled by a butterfly valve—the throttle body—which opens and closes as needed.
When a driver accelerates, the throttle body allows more air into the engine, which sends a message to the car’s central computer to send more fuel to the engine as well.

How do I service or repair a throttle body?

Many times, problems with a throttle body are related to dirt and grime that has built up. All your mechanic may need to do is to clean it.
Cleaning involves several steps, which include:
  • Disconnecting the battery and hoses attached the throttle body
  • Disconnecting the air duct to access the throttle body
  • Applying a specialized spray cleaner and using a brush and paper towel or a rag to remove the grime
Experts recommend having your car or truck’s throttle body cleaned every 75,000 miles. If you attempt this project on your own, be sure to follow the directions in your owner’s manual carefully and always begin by disconnecting your vehicle’s battery.
Sometimes, however, problems extend beyond that of a dirty throttle body. Electrical issues, a bad sensor, or even a broken throttle body may be the problem. In these cases, you (or your mechanic) will need to use an** OBD-II code reader** to scan your vehicle’s main computer to find the cause.

How do I know when my throttle body is bad and needs service?

There are several symptoms of a failing throttle body. They include:
  • Check engine light come on
  • Problems accelerating
  • Erratic idling or even stalling out
  • Misfiring
A failing throttle body can interfere with the operation of your vehicle and needs to be fixed as soon as possible.
