Sounds good! I had been fighting an issue for a while, but the issue kept changing as I was throwing parts at it. The final issue was resolved after replacing my upstream o2, even though I had replaced it only about 500 miles before. I was going crazy, because I thought it couldn't have been the o2 since it was new, but my tuner told me to replace it again anyways. I guess it was DOA, or I fouled it somehow.
