hey guys im new to these fourms so I dont know if this is in the right place.... but i have a 90' GT and I just bought it about a week ago and im getting a vibration when i hit about 30mph that wasent there before(from what i remeber)but only when i give it gas, but when i let off thegas it rides normal..... i dont know much about cars but im learning so if anyone knows or has an idea i would appriciate the feedback thank you.

 

It could be a driveshaft issue, u-joints or even an input/or output shaft isse on your tranny.

 

yea man check your u-joints
