    Do a compression test of the #5 cylinder. It's usually a good idea to do a compression test, when there is misfire on a cylinder, it takes only a few minutes. Then you know that the cylinder is sealing and you can then replace either the plug, coil, wire etc. It could also be a vacuum leak near that cylinder.
