Ok, I took a look at my car during lunch. Like I say, I don't know that much about how everything works, but I do work with electronics. The only o2 sensor I could find was on the exhaust before the cat, after the header pipes close to the firewall. You said there is a second one. I didn't see one on or after the cat just looking under the car. Is there one on top of the cat or something? Do I have to jack it up to see it? Also, where is the ECU?
The second one will be physically in the back half of the cat. It is directly beneath your dashboard, and there's a couple wires that are pushed down through a rubber grommet leading to the sensor.
ECU should be in the passenger kickpanel (far right, under the glove box)
