[v12-engine] steady misfire

Hey guys
Back on the list. I have a steady misfire at low or no load on the
cylinder closest to the firewall on the driver’s side bank (US - left?).
We checked the spark plug, spark plug wire and the injector. The car runs
ok but just shakes at stop lights due to the misfire. When it reaches 1000
rpm in drive it disappears.
Any ideas?

I had the same problem with my S1 v12. Would stop at t/lights and the car
would shake heaps. Tracked it down to a fouled plug on B6 due to a hairline
crack in distributor cap at B6 connection. A new cap fixed the problem.
