press down on one wing (corner or the car) it should go down and come straight back to the starting position. If it continues to bounce up and down a bit the damping will be shot, if there is any oil leak the damping will be shot. Also check all the mount, bushes, ball joints and suspension linkages for wear.
If you don't know what to look for pay a garage to do it or get a mate to show you. I would start by going back to the place that fitted the springs.
