It shouldn't vibrate. However, many things can cause it. Has the vehicle been tuned up lately? Has anyone checked to see if the catalytic converter is plugging? Also, these vehicles are known to lose compression in one or more cylinders. Has that been checked?
Based on your description, it sounds like you have a dead miss. In other words, one of the cylinders isn't firing. I would suggest allowing another mechanic listen to it and let you know if that is what the problem is. A trained ear will pick up on that right away.
