    the heater circuit for all three o2 sensors popped up, don't know why, they are all brand new and and the fuses are good

    the other two were for banks 1 and 2 were lean, would that then lead to my suspicion that an injector(s) are either bad or really clogged up?

    If its not reading the right A/F mixture from the O2 sensors, it might be pulling fuel and causing you to run lean... How long ago do you have them installed?
    How many miles are on your injectors?

    the injectors are original so around 142k and the o2's were just installed this summer with probably less than 1k on them

    Are you still having trouble with the O2 sensor heater circuit?
