Vibration arround 65 MPH
Before I forget this again: I noticed that a couple times, in the last days again, when I testdrive after work. I got on the Highway/Interstate and hit 65 and have alot of Vibration in my car. The seats are shakin, I mean you can realy feel that. Is that a Firebird problem, cause I read something about that or is something else going on there??
