[QUOTE="BADD281, post: 12383326, member: 67941"] I'm not sure if its injectors anymore since the upstream o2 is reading a rich condition yet the wide band right behind it is reading lean. Seems like a clear sign of 02 sensor issues or wiring. I'm going to datalog it again tomorrow with injector pulse width and o2 sensor voltages. Hopefully I can get it to misfire again following a WOT pull to see if the voltages are showing issues like the STFT did. [/QUOTE]
