Hey guys... working on my gen3 5.3 . Having an issue with bank 2 reading lean. My wideband is also in bank 2 and follows what the narrow band is saying. I've pulled all the injectors and cleaned/flowed them. Swapped them side to side while doing it. Changed plugs, moved coil packs side to side, moved O2 sensors side to side, fixed any possible exhaust leaks that i could find pre O2. At my wits end.... running out of time before Sick Summer to get this car right. Any thoughts? Car was doing fine... one day just started running lean... and it shows its on bank 2. I turned closed loop back on today and even though its showing lean, its got negative fuel trims....which confuses me. Short idle log and tune attached...
