Okay, this is a weird problem I am having with my car. From about 35-50mph, the car will vibrate pretty bad. Now, heres the kicker, the vibrations ONLY occur when I step on the gas hard. Even if I am at like 35mph, in 5th gear, and go to full throttle, where the car will obviously not accelerate hard, it will still vibrate (even a bit harder in this particular gear/speed setup) At a constant speed, however, the car is just as smooth as it should be. Could this really be a wheel out of balance? I dont know what else it could be, but if it was a wheel out of balance, the fact that my foot is on the gas shouldnt have anything to do with it, correct? PLEASE SOMEONE HELP ME!!! This problem is driving me crazy! Thanks!!!! -Nick
