I would like to know what would remedy a severe shaking problem when starting up my station wagon. The car runs fine(smooth)when it is started, which is right away, just the inital cranking which shakes the whole car. I have changed both the engine and tranny mounts. The old engine mounts were broken. I am stumped. I have a 1987 and 1990 240 sedan and they start smoothly, no shaking at all. Any input will be greatly appreciated.

P.S The electrical wires that goes through the trunk hinge on both sides goes are broken, causing the license plate lights and the brake light on the trunk lid not to work. Is it difficult to repair?
