Carbon buildup is cleaned from the throttle body so air flows smoothly. It may help with rough idle, stalling and slow response.

Questions to ask before you say yes
- Will you reset the idle relearn?
- Will you clean it off the car?
- Is the intake checked too?
- Does my car need this as a normal service?
Can you do it yourself?
A fair DIY, but don't force an electronic throttle open by hand, and follow an idle relearn procedure.
Common questions
When is cleaning needed?
When the idle is rough or surges, or the car stalls at stops. Carbon builds up around the throttle plate and restricts air at low speed.
Will cleaning fix all idle problems?
No. Vacuum leaks, bad sensors, dirty fuel injectors and worn spark plugs can cause the same symptoms. Cleaning is a quick, low-cost first step.
How often should I clean it?
There is no set schedule. Many cars never need it, while others benefit every 50,000 to 75,000 miles. Clean it when the idle starts to act up.
How much does throttle body cleaning cost?
A typical range across the US is $75 to $180. That is an estimate from parts prices, labor hours and the local labor rate, not a quote.
