Miss-fire, help.
My SL65 has developed a miss fire, you can feel sometimes it's on 11 and
sometimes it gets rough like 10 firing. I had new plugs a couple of months
ago, and I checked with the tuning company and they said it might be
coil packs. Also I haven't driven it much, yet it was fine this morning, miss
firing tonight. Any body got any ideas what it might be.

Whenever anyone tunes a 600/65, these ignition coils tend to go out right after the tune, mine got bad to the point where i was driving and when I hit around 90 mph the car went really rough.
Turned it off and on after 2 mins and I was good again but when I ran my OBD II scanner it should 10/12 cylinders misfired
