When I pulled the car out of the drive way and get a few feet to the stop sign it started virbrating, only when stopped, sounded like the bumper was ratteling on something, but it wasnt I opened the hood and it seemed to be the entire engine knocking/ratteling. It has done it a few times since.
Almost like the entire engine is loose?

wtf.

I cant explain it very well.

 

bad motor mount maybe....

 

Im not sure, wouldnt it do it ALL the time though?

Not like 2 or 3 days a week. and only once each time?

 

sounds like a motor mount

 

Great..
