Sorry you are still having misfire codes in the honda! Is this a misfire you can feel all the time, or is this a misfire that happens as you are driving under load?
Customer: replied 6 months ago.
All the time on idle, but runs smooth after 2000 rpm approx

Someones just one cylinder misfiring can set a code for multiple cylinders. Since the coils are easy to get to, with the car running, unplug the coil in cylinder 1 and see if there is any change in the idle, and do the same to cylinder 3 and let me know what outcome of that please. Thanks
