Throttle body issue? Cleaning?

Hello,

There are few reasons this can happen.
It would be good idea to clean the throttle body if it has not been cleaned in a while. However most times dirty throttle body will cause power loss issue just about any throttle.

Could also be vacuum leak that causing this issue.

Is your check engine light on? If so do you know the codes?
