Guys need help V6 engine shaking

[Randy]

Ok guys a few days ago i was asking about what plugs and wires to get for my wife's car.... well i needed to replace them because the engine is shaking pretty bad, but i cant really feel the car jerking like it is misfiring.... so i took it to a shop and they wanted 300 for plugs and wires.... eff that i swapped them myself and its still doing it..... have you guys ever heard of something like that happening??? Any suggestions as to what it might be? I took a short vid that's uploading now of the issue so any help would be greatly appreciated.

Thanks Randy

Pretty common, harmonic balancers take a shit, its likely broken and spun inside its housing

If it was misfiring it should be throwing a code.
