I just talked to a ford dealership tech, and he said that I would need those back 2 sensors installed, or the car would run lean. He also said that I would not need mil eliminators when i installed the sensors. He basically was saying the opposite of everyone else I asked, including you guys. He is pobably just a dumb***, but that is what he said.

YOU NEED EXTENSIONS AND O2 SENSORS ON THE FRONT. AND YOU WILL NEED THE MILS FOR THE REAR PERIOD. The mech who told you different has no clue about your set/up or what he's talking about, Make sure you reset your computer when you hook everything up if your throwing a code. I did this post 3 months back and found out the hard way. I havn't thrown a code since.
