Cost to replace motor mount/mounts? on 1997 Nissan Quest

It has an extra kick to it when applying pressure to the peddle too fast. I've also had numerous people tell me it's the motor mounts. Not sure if it's 1 or more, or which one it is. What's the cost for 1 or possibly more, labor and parts? Or even the cost of just a diagnosis?

I agree with Roy have it checked out I have replaced at one time or another each of the engine mounts on a Quest front mount a little more frequently than the rear.
i suggest the diag to get an exact issue and a good bid. the diag should be around 20-30 range.
