One of the most common cause of cold misfire is a failed plug wire. Have them ohmned to see if any is out of specs.

Check applicable trouble codes. If a miss on one cylinder, the code should tell you which cylinder. A miss at idle is way more noticeable than at highway speed. A miss at highway speed may just show up as some loss of power.
