Default Excessive Vibration and a Vacuum leak

I own a 96 V8 Grand Cherokee Laredo

My jeep started to have hard vibrations. My Jeep is very shaky, the seats visibly rock back and forth and I feel strong vibrations when sitting inside. It has the same vibrations when in park and neutral but it shakes even more when in reverse or drive. It also has a kind of sputtering nature to it.

When I connect a computer it shows a vacuum leak. Through my own research ive seen that it could be a cracked manifold but I simply am not a professional mechanic so I really dont know.

Can someone please help me out with suggestions and opinions?
