2008 Chevrolet Impala Idle vibes

Had my car tuned up 4 days ago and it runs great and the idling is great until I come to a dead stop at a stoplight and there’s a little bit of vibration in the steering wheel and it just seems like the idling is not right when I’m stopped

Have someone try cleaning the electronic throttle body.



One or more cylinders with low compression is also a possibility but a dirty throttle body is a much cheaper repair so hope for that.
