My step-sister just bought a 98 Stang. I haven't looked at the engine bay since I don't have access to the car, but I was wandering how hard the o2 sensor was to get to? I am well versed mechanically, but I was wandering if the o2 sensor was a PITA to get to, or relativily easy. It has the check engine light saying that the o2 sensor was throwing a code, so I am going to replace it.
