Oh btw, my E39 used to have starting issues, as in long cranking if it had stayed off for more than one day, and starting issues when warm and "laggy" acceleration up untill 3000. I replaced 3 coils (since I didnt check the codes I took a chance and replaced 3 randomly) and the issues went away. Although I should mention that I replaced fuel filter and crankshaft sensor a little earlier, was going to replace the camshaft too but never got around to doing it.

But like I said, oil in spark plug holes is often caused by leaking valve cover gasket. I believe that CAN cause some running issues as well. If not, its still a very common M5x thing.
