I've had this CEL come up a couple of more times now, but it's very inconsistent. I've read of guys getting this at the track and it's a faulty coil pack, but I get it when cruising in town. The one time I had it come up while I was logging, I couldn't find that spot in the log to save my life (it was a 40+ min drive or so). That time, I was going up for a mountain drive and got the CEL on the way there and again on the way back...NOT when powering up or down the mountain.
Just happened again this morning on the way to fuel up (yup, still E85). Cleared it and didn't see it again on my way to work (30-ish miles).
I went out on lunch and logged (up an incline...no flat roads here).
3rd-4th gear:

Pretty sure this was 3rd also...

Anyone have thoughts on this? I'm no tuner, and have been learning as I go, so I can't just look at a log and go "yup, looks good!" To my untrained eye, nothing looks terribly disturbing here.
I'm not overly concerned that something will blow up, since the CEL doesn't come back consistently and there are no strange noises. I'm inclined to agree with the guy who said it was likely a rich condition, but how rich does it need to be to throw this code? I thought it was the E85 pump, so I filled up the last two times at the slightly more expensive one nearby and still got it.
Maybe the answer is to just add the OFH...
I'm halfway tempted to switch back to (shudder) 91 octane and see if I get the CEL, but when I see the $4.05+ sign, I cringe. Especially knowing that I'll lose most of the OOMPH.
