No. Sounds like either your engine mounts are bad (unlikely), or that you have a number of cylinders that are not firing. When I first picked up my 240z, I experienced the same issue. The engine mounts looked fine, so I started pulling plugs wires off the plugs to see which cylinder was not firing. Turns out I was only running on 4 out of the 6 cylinders.

It may have something to do with the car being cold. I am not an expert, but my '73 does the same thing for the 1st 5 minutes of running after a long sleep. It does not happen when I start it while still warm, only after being parked for over 4 hours. That is the main reason that I start my car, let it idle while I smoke a cigarette, then I drive her after she has had time to warm up. I may have something else wrong with her, but it seems to work.
