So my 2004 350z is shaking uncontrollably. The shaking tends to get much worse when I shift from park to drive. Besides the shaking, there is serious loss of power. My car does not accelerate like a 350 is suppose to. Sometimes the car has trouble getting past 45 mph and above. Any ideas?

 

I would recommend taking your vehicle to a Nissan dealership immediately!

 

Any CEL? Where does the shaking come from? Front, back, any noise along with it? First blush guess just from description is bad motor mount. But could be anything given description. More details needed....
