Ok so ongoing issue. 2001 530 133000 miles. Been having ses light with bank 1 and 2 over limit lean condition. Found and repaired. Cracked valve cover by cylinder 5. Or so I though. Hooked up my creator 310 now have short term reading of -.06 on 1 and -.09 on 2 with long term hovering around 11.0 on 1 and 12.0 on2. How can fuel be taking away and adding at same time. Makes no sense. I have smoke tested this thing to no end only leak was valve cover. Other than that u name it I have replaced it trying to end my rough morning idle and lean condition. What do u make of these fuel numbers. My fuel pressure was perfect as well running and holding pressure engine off. Battery numbers perfect aswell.. o2 sensors cycling perfect and after cat holding steady at .74 as well.
