Throttle Body buying guide
Why replace this part?
The throttle body controls the volume of air entering the engine in response to accelerator pedal position. Carbon buildup on the throttle plate causes rough idle, stalling, and poor throttle response. Electronic throttle bodies can also fail mechanically or electrically.
Signs you need a replacement
- Rough or unstable idle
- stalling at low speed
- poor throttle response
- check engine light with throttle position codes
- hunting idle after a cold start
When to replace
Clean every 50,000 miles with throttle body cleaner. Replace if the bore is worn or if the electronic actuator fails.
