Engine Performance problem
1998 Ford Taurus 6 cyl Front Wheel Drive Automatic 126000 miles

Car started shaking, so took in to get it checked. Cat. Converter was bad, so that was replaced, but car was still shaking. Quick diagnostic code showed miss-fire on cyl 4.
Changed the plugs and wires, shaking was still there, changed the coil pack next, shaking still there.
Going to reset the error code and see if same error comes back.
If it does, what would be the next item that you would check or replace? The EGR Valve? O2 sensor? Fuel Injectors?
