Hello and thank you for helping me. My problem is that when I get over 35 mph and accelerate it has a bad vibration in the front end if I let off the gas it quits.

Check the motor mounts first, you may have a loose/broken/collapsed mount.

Then check the brake rotors for any warping, nut the fact that is dissapears when you take load off engine (release gas pedal) it sounds more like a mount.
