R33 trouble. Are my coils the culprit? Please have a look...

I'm having some trouble. Put new spark plugs in gapped to 0.8mm. I thought the coils looked ok. Couldn't see a hairline crank on the front, though maybe I missed it. But most of the coils had stange bits on the side where it looked like they had seen lots of heat.

Just lately I get a misfire, well more like a boost cut but it happens at just above 3000rpm up a hill in 4th gear at 0.65bar (about 9.5psi).. I thought maybe it is the ECU sensing too much airflow and going rich and retard. But I thought this would be at more like 12-14psi...

Can somebody have a look at the pics below..not the best but gives an idea of the what is going on on the side. I heard somebody in the thread saying the heat on the side may be from arcing?
