    My 960 suffers from rough idling once the engine warms up.
    There is no visible fluctuation on the tachometer but a steady,
    periodic rock that makes the car shake. I thought there might me a
    misfire (spark plug, cable), but on the road it runs smoothly.

    Also, what would be the best literature on self-repair for European

    It's a 1995 with 108k miles.

    any help would be appreciated.

    960s have problems with the intake manifold gasket failing. Look for
    vacuum leaks there. (And everywhere else too!)
