i just bought a 99 z24 on monday, i have noticed when i am stopped at a light the car shakes a bit, i can feel it shaking... just a little strange. its like the car is moving back and forth lightly, and slightly side to side. kind of makes me a little dizzy if i sit there and pay attention to it. my old daily driver was my good ol' trusty 93 sunbird, which didnt shake at all while idling. im just curious if this is normal for the 99 z's or not? any feedback is greatly appreciated, thanx.
