I had this code before...I have a ram air hood and I noticed it popped up every great once in a while when it was raining or snowing. Can you look at your misfire counts on each individual cylinder, that would narrow it down a lot.

I have done the re-learn. So far no codes yet. I'll keep you guys posted as to what happens in the next few days. I'm gonna go back and check the tune once it gets sunny again. James B.- could you clarify the difference between open and closed loop? Thanks a lot for all the ideas.
