Just purchased my E92.

When I start it cold, it seems to idle reallyy rough. You can see the wheel shake, not drastically, but until I grip as if it's like the wheels are out of balance very minimally. Also you can feel a rough vibration when its at a stand still as well as, after a few minutes, driving until it's 'not running cold.'

The RPMs seem to be a lot higher (which is expected) but does not maintain consistency rather "bobble" up and down (within a small range).

Once the car is not idling "cold" anymore it sounds completely different! When it idles cold it seems like the car is a beater!

What's going on?? What can I do?

Start with the usual suspects, see if its throwing any codes, check plugs, maybe an injector, the list goes on. But I would definitely start with codes then look at plugs/injectors, how many miles on your car? Maybe its time to look into walnut blasting.

Sorry if some of this doesn't make sense, I don't have a 335 myself but I figured i would try to make a suggestion based on other people's stories I've read on here.
