Just change the O2 sensor,you will have to pull the floor mats up,
liner,remove the front plastic kick panel,and a nut or two on the
hold down clamp,undo it plug up the the new one.Make sure
you use some PB blaster on the old 02 a couple of days
before you try to change it.Takes longer to jack up the car
and slide under it than it does to change it!!
