When I first bought her, she had the shakes bad. Items replaced to remedy the shakes:
1. Engine Mounts
2. Engine shocks
3. Air filter bracket & mounts

While replacing the bracket & mounts I learned that I needed a new air filter housing as the drain was not right. A piece of rubber fuel hose came out of the oil separator instead of the metal pipe. So I replaced the air cleaner box with one that has a metal pipe that sits in the drain receptacle tube.

Since the drain has been properly seated, the car gets a case of the shakes every once in a while when I take pressure off of the gas. I also need to get the wheels balanced, but this seems like it is more than those shakes...
