Just tried again started up fine and seems to be running good

Most Daihatsu coil pack unit problems I have had, have been caused by the rubber down tube bit under the coil itself.

You can pull them off, then check the metal conductor inside for continuity.

And sometimes by bending the wire bits at the end you can make them work better again.

You can swap tubes and heads with other coil units, and see if the misfire moves to the other cylinder.
