Default High Speed Vibration

While I was on the freeway today I noticed a vibration in my car that I'm pretty sure wasn't there a month ago. It really only does it when the car is cruising or coasting. If there is power going through the transmission its smooth as can be. As soon as you let off the gas though, there it is. I don't know if my rear is going out or what. I'm not quite sure what it is so, any help would be appreciated. Bytheway, I have a T-5 tranny if thats makes a difference.

Does it vibrate at certain speeds or certain RPMs? If it's speed related and not RPM related.. have you checked your tires lately? Could be something in them, could be off balance, tire could be damaged / cupped, etc.

I notice it more at higher speeds, but its pretty constant. The tires are fine, in fact I checked them already. RPM's don't seem to matter either...

I don't see how it could be wheel balance if its not doing it all the time though. Under acceleration it goes away. Is this normal if a wheel is out of balance?

You can pretty much feel it coming from the entire car, but it seems localized in the rear.

Well, I discovered the problem and you guys were right. One of my weights came off my left-rear wheel. The clip is still there, but the weight came off. I just overlooked it yesterday since the clip was on. der der.

Thanks for the help guys. I appreciate it!
