Default Surging, vibrations and more oh my!

I have a new round of problems coming out of the Stang again! Recently noticed surging (I think this is what you would call it) coming from my car, it really doesn't matter what RPM I am at, I feel a surge (kind of jumping forward ever so slightly). I don't notice the RPM or speedometer going up when it happens either.

I also have a vibration! This rarely happened so I paid no attention but today it was horrid, it occurs right around 2k RPM and I can see the passenger side seat vibrating clear as day. I didn't notice if it only happens when I rev the engine (this is when I noticed) or if it occurs when I cruise around there too.

And the last but i'm sure not least, I hear a sound coming from around the shift bezel area when I am in neutral, its like a hallow whoosh or something, everything seems fine when in gear.

Lemme hear the bad news guys! I'm not too worried, as I hopefully have something in store for the car in the up coming months, but it's always nice to know what's going on!

Thanks a million guys,

have you checked your u joints. your front one from the sounds of it, if it goes it will shake the transmission really bad. if the rear one starts to go.. the whole back end will go wild on you.
