Hey guys so im hitting the 150,000 mile marker on my 97 mustang v6 and well I thought that maybe just maybe I need to replace my o2 sensors. Since we never have replaced them since we bought the car brand new back in 97. So anyways I am having trouble locating the sensors, I see one right away after the cat but I cant see the other ones. Now I have been researching all damn day and I cant find crap on this things and I have read from more then one site that it has 4 sensors is this true? Now another questions is I dont have cats on my car since they got damaged a while back so I took them off since its not a must here in texas
. My question is if I put the sensors brand new all four by me not having the cats will the o2 sensors get damged after I put them on? I just feel dumb asking this questions but they need to get answeared. Please any feedback will be greatly appriciated. Thanks.
