if your sure the coil is ok,then get a compression check.
could be injector,had one before
valve clearence,not had any issues
or engine damage .none so far.
try you local mot place,get an emission check done and post the results,it can point to the culprit.

I have a 55 one of these which had an intermittent misfire which started when it was about 18 mths old. I noticed it only did it when running on supermarket petrol. It was cured through regular (and continuing) doses of Redex injector cleaner. I put this in every 3 months or so rather than with each tank of fuel. No problems since no matter who's petrol goes in and it got a very clean emissions report at it's first MOT even though it only does short runs.

If it has been misfiring for long it may well have killed the xhaust catalyser thingy.
