I'm hoping they share a coil or something that I can easily replace without having to go to the stealership.
Consider moving coil 5 and 6 to 3 and 4. Then run the engine see if the problem moves. If it does it is probably the coil.
If it doesn't move change the plugs. If this doesn't clear the miss you may have a bad head gasked if 5&6 are twin cylinders. I dont' remember the exact cylinder positions.
