5.7 hemi idle and backfire

AJ i have thought about that same issue im not sure what happened it was running fine and just suddenly started missing and small exhaust backfires until i got it home about five miles or so. im thinking it may be too rich but im not familiar enough with the diablo system to know how to lean it up and i dont want to make it too lean that could be worse. the o2 sensors were not that bad when i removed them im kinda hoping it just might have been a sensor that took a dump and wont happen again but who knows
