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 cars?
It's a 1995 with 108k miles.
any help would be appreciated.
