on the way home my exhaust rattled really bad. I jacked it up and got under it when I got home, and noticed that both of the shitty home depot bolts were loose and about to break. This whole time I had a really bad exhaust leak. There way black soot shit all around the donut gasket and both the long downpipe/straight pipe gasket. Picked up better bolts and put it back together. The car runs so much better now. Not much chugging, KR readings didnt go above .9 on a 30 mile drive. The power is more than it has been also. It feels ~40 hp or more better than it was before, and the log looks pretty clean. I guess that was the culprit.
That would do it. The noise from the leak could have caused false knock or enough fresh air could have gotten in to do funny things with the AFR.
