specific story

hey, i am looking for  a story i read on ff.net ages ago. it was a story about both brothers. In it Sam ends up with bruising on his throat when working on a car with bobby. sam and dean go off and have a car accident and get separated, Sam cant call for help and dean and bobby frantically search for him.  It MAY have been set after johns death as Dean starts off the story angry at Sam and they are at bobbys..... any suggestions where i can find it?  It was very much a limp sam story
