After I stop at a stop sign, when I accelerate there is a clunk and the car seems to jerk. Seems to be fine on the road.

A couple of possibilities come to mind. First, there could be one or more bad CV joints. Second, one or more engine mounts could be broken. A good independent shop can diagnose and correct the problem.
