Did you have the fuel pump recall done? if you didnt then get it done to see if it is causing any issues. if it was done, add some coolant dye to see if coolant is getting into the cylinders some other way. Finally, swap the coils individually to see if it changes from five to six.

 

Is the misfire readily apparent as a rough idle or other? The misfire code is generated by a change in engine speed, and may be related to a cam or crank sensor.
