Only owned it since September(ish) last year. Temp gauge never goes up past half way, regardless of weather.
If heat was the issue (and I'm not saying it isn't) why only a short misfire then nothing. Something failing due to heat would surely continue to fail??
Anyway I will try and check everything mentioned.and see if I can find any clues.
My coils where out like 10-30 seconds so your misfire is way shorter than what I had. No Idea why they are out so "little" but if they cut and the engine runs on two or three then there is less current going thru. But if it was the coils one would think they would not cool down so fast.
Could be a limp mode or something inside them, Coil fails does not show on the ECU diagnostics.
Swapped out the plugs (iridium and all looking the same) for a set of standard NGKs.
Coil packs look very clean, and identical in condition. No damage I could see.
Air filter was replaced only a few hundred miles ago, along with oil change.
Anyway. Short drive and the issue is still there.
It does not happen until the temp gauge gets around the mid way mark where it then stays.
I'll try and get a coil pack to swap in next.
Other thing to mention is it starts on the button every time and runs fine up to the mysterious misfire.
Has to be heat related I think ....
Well today's trip was not so uneventful.
Seemed to get past the usual misfire spot but a few miles further on misfired like a devil for much longer. Like minutes. Narrow road with no opportunity to stop. When I did stop it cleared and was fine until I reached my destination a few miles on.
Swapped the new coil pack for the old one and six hours later made the return journey. This time it started misfiring around the usual time but again for much longer.
So more swapping to be done.... ☹️
Put the new coil pack in place of the front one this time, that was a few days ago, and so far so good .... real test will be Monday when I have a longer more important journey to make!!
