    Frustrated car is idling rough

    Car starts and drives but it just idles rough and engine is shaking.
    Creator c310+ shows cylinder 4,5 and 6 misfiring. No other codes
    shown. I cleared faults installed new plugs and coils. Torqued them
    To factory spec. Still idles rough. I switch the plugs from cylinder 1,2 and 3
    to 4,5 and 6. Cylinder 5 shows is still misfiring. I tried getting a different
    brand of plugs. Same results but this time cylinder 4 and 6 is back.
    cylinder 5 always remains. I check for vacuum leaks, clean vanos sensor,
    i cleaned maf sensors. Same thing. There are no codes for 02 sensors.
    cant be fuel injector.
    could it be the eccentric shaft sensor? I do notice some oil covering it.
    i have a 2007 BMW 328i coupe n52
