2008 Mercedes C300- P0305
 

Hello,
I have a question with the code P0305 and I was wondering if any of you guys could help? A few weeks ago I changed my intake manifold since that plastic piece broke and decided to replace the entire thing. The car ran fine afterward and a few days ago I noticed a slight shaking when I put the car into either the D or R position it would do a slight rattle under 1k rpm and go away until I hit a complete stop and then proceed to accelerate again. If you have advice or suggestion please feel free to drop it below

Responded to this in your other thread.

Sounds like a vacuum line came off take a can of brake cleaner and spray around area you worked in hopefully you can track it down. Good luck :)
