what problem have you had with your 02 sensor?

rite now i am not able to accelerate past 3800 rpm it only bogs. i have used my ecu code reader and when my code reader picks up the o2 sensor (dcc1 1 long lite 1 long pause) it goes into failsafe mode and shuts and stops feedback from the o2 sensor then my car works fine. i am hoping its a simple swap from defective o2 sensor to non defective o2 sensor. if anyone has any comments please feel free to comment on my problem or the question. :D
p.s. this is a new ngk o2 sensor and am going to a bosch o2 sensor now

sounds like secondary injectors...? don't think bad o2 sensor or link would keep the rev down

Renegade_07, It seems you haven't made your way down here again like you were supposed to. ;) Maybe soon? Have you replaced your Pressure Sensor? Fuel Injectors Primaries>Secondaries, vice-versa?
