when you say swap the o2's, i thought there was only one 02 sensor, located on the passenger side pipe? do you mean replace, or is there a second one?

What they are talking about is swapping the right and left side O2 sensors to see if the trouble follows the sensor from the right side of the car to the left side of the car.
