KA24DE Shacking Problem

[KingMidas]

I just bought a 93 Hatch. It was shacking crazy. I checked the injectors. #4 injector when I unpluged it didnt change. I changed it out yesterday. Put some mid grade gas in it and drove it around the block. That helped it alot but it still shacking. What could be the problem. Looks like there is a newer fuel filter on it. I havent checked the plugs or wires yet. Could anyone that has had the shacking problem give me some tips on things to do and check so that I dont start throwing money at the car and it not be the problem?

Thanks a head of time!!!

First of all its spelled "shaking"
Id just go ahead and replace the plugs(gap them first), cap & Rotor and wires.
I do that on every new car I get God knows when the prev owner did it.
