Ok here we go.
Can anybody please tell me if your O2 sensor is goe's will the Check Engine light always come on and stay on. I'm asking cause i think mine went before i brought the car, but it never showed up on Nissan's diagnos. unit when plugged in. It has always run sluggish and when we got it it had bad fuel milage. I'm asking cause i am going to buy another O2 sensor but i dont quite have the funds at the moment and have other priorities to spend the money on first, but if it is the O2 then i want to buy a new one soon as poss.
Thanks and any help would be appreciated!
