Default On track Temporary Limp Mode

On Saturday afternoon, after about 20 mins of lapping (80F outside, , car bogs down on power and goes into limp mode. CEL came on, but could drive the car back into the pits without issue. After half a lap, light went off and car seemed normal again. Next day car ran without issue.

Pulled the codes today and had the following.

First seems to just be secondary air pump, which I'm not all together worried about. 2nd is something related to the clutch switch, which seems to be unrelated.
3rd error is the one I'm not really sure about. It seems like the error might have been a cylinder 2 misfire?Could an overheating/dying coil pack cause that?

Ah okay the symptoms sound very similar to what happened to me. Although I figured it was my DSC since it was turned on. I'll find out since I'll be heading to the same track this month to test it out.

Iíve found that when one coil pack goes, the other 5 are getting close. Youíll end up killing 2 or 3 more.

Iíd just replace all 6.
