Thanks for the information. I have read the posts and I am not sure if it is the same issue but it could be.

When I first start the car after sitting for maybe 8 hrs. the idle speed is 1200 rpm and that is when the car will actually shake and it feels like it is missing. As soon as the idle drops to around 800 rpm, it is perfectly normal.

Just curious, does everyones' 540i's go to fast idle (1200 rpm) even on a hot start? Mine does and I've owned many cars and that seems a little strange.
Just asking.......
