When the car is idleing it vibrates very rough along with a knocking sound coming from the engine,but
when you rev the engine the vibration and the
knocking goes away.PLEASE let me know what you
think.

Without actually hearing the noise, I can only guess.
It could be a "slapping timing chain" or rod bearings. Either would be serious and would have someone knowlegable check it out.
