Have you checked the Motor mounts?
My vibration was with hard acceleration and horrible vibration around 65-80.
Did they say anything about your drive shaft when they balanced it?

Moto mounts checked looks good , very mild virbration feeling on steering wheel as well as driver seat , only on crusing light speed if i press hard gas pedal i dont feel anything .
Do u guys think this would be a clogged injector ??

No, a clogged injector would throw a code if it were that bad. Get yourself a Tech2 and this way you can monitor the engine in more detail.

I know you have had your tires rotated/balanced a few times but it could be a tire thats slightly out of round or a rim thats slightly bent. I had a slight vibration at 65-70 with two different sets of wheels and i figured it would be something in the drive line like drive shaft or anything. Well i ended up buying some take off 22s from a denali and all went away. Even if a wheels balances out on the balancer, it may not detect an out of round condition.
