I don't have a good diagnosis, but I will tell you that I run a can of SeaFoam ($8.99 at most auto parts stores) to clean out my '06 550i a couple of times per year, especially on road trips. It could very well be an injector issue, and that it just needs a good cleaning. If you are savvy enough to remove the spark plugs, pouring some of the SeaFoam directly into the cylinders to soak the piston heads can really help clean things out. Just enough to coat the piston heads, and a little burst of air will help spread the cleaner into the cylinders. SeaFoam is pretty amazing stuff when used this way, along with running it through the gas tank. Good Luck, Patrick

Thanks pburke911.... I have tried SeaFoam.... not directly into the cylinders though. I was wondering if it could be a vacuum issue or a fuel pump issue or even a control mod issue?
