also check your waterpump and fan. If those are bad they sometimes wobble and cause what you are feeling.

Try removing the waterpump/fan belt and start the car for a minute just enough to see if it smooths out.

If that is not it next try the harmonic balancer (79 bucks brand new 50ounce).
If that is not it then it could be anything in the drivetrain from driveshaft to transmission, etc.
How are the motor mounts? transmission mounts? are they new?

Any of these could cause your problem.
