          Mine does it as well. The one on my Monza too. I think it's normal.

              Vibration from the ICV when the ignition is on is normal.
              The car makes it possible, but the driver makes it happen.

                          yeah, I knew it operated somewhere in the 90-something hz range, then I saw a BMW doc that stated all the PWM valves (ICV, EVAP, etc) worked at ~100hz, and then somebody posted they scoped it at exactly 98.3hz. :D
