Well, sure enough, the light came back on this morning on the way to work. That didn't last very long! It was the same scenario. I was just sitting in stopped traffic when it popped on. Is it possible that it was the gas that I put in it? I always fill up at the same station (BP), but this last time I went somewhere else (still BP, but another station). I am going to take your advice and try Chevron w/ Techron. What exactly is Techron and why is it helpful?

Does anyone know if this is something that would be covered under an extended warranty? (If it is in fact an O2 sensor)
