Hey I had the same problem with my 91' bird, where it would shake real bad around 2000-3000 rpms. After chasing it for a while I found out that the harmonic balancer had gone out about 90 degrees. So check that. It could possibly be the prob. Also check the disstributer/rotor if thats bad it will also make it seem that the car is misfireing or shaking real bad.
