CaddyShack24 Posted July 2, 2004 Report Share Posted July 2, 2004 Fuel Trim System Lean Bank 2. sounds like bank 2 is adding time to the injectors due to a lean condition, maybe an o2 sensor cat conv... how did you come to this conclusion, it set a code? would be good if you could access the fuel trim values off the PCM i think bank 2 is cylinders 1,3,5,7 (dont quote me!) might be related, changing something with fuel distribution, but the cause would have to be something else not accepting the new flow of fuel .. edit: was thinking, maybe the fuel rail isnt seated properly Link to comment Share on other sites More sharing options...
