i think my o2 sensor is broken becuase it seems to cycle while i am idleing, which is normal, but then it will keep cycling even when i am just cruising and i was trying to tune it and i just could not becuase the reading was never staying still. the o2 trim also changes all of the time so i could not tune it becuase of tthat either, it would not stay still even while i way just cruising. does this mean my o2 sensor is broken or is that how you guys tune it, with the o2 trim like never staying still along with the o2 voltage?
please help
