It's the Neutral Idle Control. The first step in SIB, is to update the software to smooth out the bump feeling, second step if that doesn't work is to deactivate the NIC feature completely. They just did that to mine last week. The Car is running silk smooth now.
Do you know where I can show them this SIB? I told my dealer the exact same problem and he just looked at me funny and said he's never heard it before.
