Does anyone have a good 2.0 D-jet throttle body return spring? The spring that pulls the throttle butterfly back down to idle?

I probably have some in my collection. I used to pull them off of Mercedes cars in Pick a a parts yards. You can rebend the straight section of the spring to get the right tension. Unless you are going to be a weenie and want an original Porsche part.

I'll take what I can get

If Bruce doesn't have what you need, check out your local auto parts store. I bought a pack of throttle springs for a few bucks and found one that works well.
