    Loss of Power Problem

    I have an '02 E39 M5 with 75k miles.

    I have a loss of power problem. Used to run like a bat out of hell. Now it runs... eh. The dash doesn't show any faults. I've cleaned the air filters. I got the spark plugs changed and it ran really, really great for 24 hours and then it went back to blah.

    I'm hearing it can be the MAF sensors and the computer just isn't catching it, etc.

    What do you guys think? I need my car back to the way it was.

    Sincerely,

    Depressed Scott

    Scott have you checked if your spark plugs are getting oily at all ? Just had my Rocker Cover gasket replaced for this apparently common problem in E39M5's
