    Default Rough idle at start up

    Anyone have some thoughts on what to look at first? When I start the '95 525i up after sitting for a few hours, it idles rough for about 15 seconds, then all is well.

    ???

    Maybe leaking injectors or a bad check valve for the fuel line.
    If the check valve is leaking you will have bad cold and warm starts
