engine vibration on 1994 Geo Prizm

just bought a 94 prizm have a vibration that is coming from the motor.Checked all of the mounts all are good. Everything is in great working order. Thinking maybe harmonic balancer is going bad. Vibration goes away at freeway way speeds no tach so dont know what rpm. Any ideas or suggestions?
