BMW E30 smokes on startup(not oil)

My 1990 BMW E30 smokes black on startup, especially if I rev it to about 2-2500. And it smokes black when I close the throttle. ONLY when its cold, and it smells strongly of unburnt gas. Wondering if it could possibly be one or more of the injectors possibly stuck open? Any help would be awesome.
