sounds like it could be a bad adjustment on the TPS. check it and see. if not, check the failure codes. that should point you in the right direction.

I have the same problem with my 70mm TB. If you give the car a tiny bit of gas, and I mean tiny, does the idel calm? If yes, you can just drill a small whole in the TB blade. Start with the smallest bit and work your way up. You will have a higher idel, but should level it off. I have not done this to mine because I may be selling it. Maybe someone here has done it....
