Any idea of the service history? Could be a plethora of things..
Vacuum Leak Bad Gas Fuel filter air filter ECU The list goes on.. Any other symptoms? Check engine light? throwing codes at all?

Changed Plugs..
I haave the same problem and I changed the plugs and coils and I have the same problem still but not as bad as before. I will take mine 760li to the dealer when I arrive back from Amsterdam. I think this is the best solution for this type of problem. I've been to several places and they tell me the same ol story about the coils and plugs. Will let you know more when I find out the problem with mine car.
