cold start problem with e39

I have a 97 e39 540i and Ive been having issues during cold starts especially through winter. Starting the car is not a problem but when started the rpm dips down as if the car is going to die and right when its about to shut off it automatically shoots the rpm up to stay alive. When i start moving its okay but at a light while idling the same thing as if the engine is struggling to stay on. When the car warms up everything is fine even when starting while the engine is still warm everything is fine. Ive tried looking for this problem but can only find starting issues....any ideas?
