Default Vibrating LS1??

I have a 99 z28 A4 and i seem to get a vibration at around 1600-1800 rpms. It does it when i drive, and also does it in park when i hold the throttle at a steady RPM. I know this cant be normal, but has anyone else had this problem? It feels like it pulses if that makes sense, it will vibrate enough to shake the steering wheel, then smooth out, then vibrate some more. The engine only has 60k miles. I have no idea where to start, help?

mine does that too, every time i start it in the morning the steering wheel vibrates a little and then once the car warms up and the idle drops to around 600rpm from 1000 the shake is gone. i don't think you should be too worried about it. good luck
