Was enging running ok prior to installing new plugs and coils? Did you check spark plug gap before you installed them? I know some people who assume they come pre-gapped from the box. Re-check connections to the coils. If these items are the only parts you replaced, I would have to guess that #5 plug could be bad, coil could be defective, or a connection problem. (wire, connector, etc)

Assuming she ran great before the work was done, swap the coil with #6 and see the the misfire follows the coil.

Likely that the coil wire isn't snapped in all the way. Happened to me when I did my plugs. It looks right, but will come right off if you tug on it.
