I'm not sure whether I should get O2 sensors moved. Your thoughts?

Could be a stuck lean rear O2 sensor. This sensor is to check catalyst efficiency, sounds like the sensor could be bad. Recommend to replace the O2 sensors.
There are already four (4) oxygen sensors on the 2.8L V-6 engine; two each side of the exhust; one sensor each upstream and downstream of the catalytic converter. Find a different dealership or repair shop.
Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.
They (Rock Auto) list the O2 sensors from around $43.00 each for your vehicle.
Walker Pro 5/7/2013Hello Alan,
Since your vehicle has 134k miles on it, moving the sensors may have delayed the inevitable for a short time. It is likely you will need to replace all of the sensors soon. Replacing them now may prevent catalytic converter damage as well. We are not sure how they were able to swap the sensors since the front sensors are 610mm long and the rear sensors are 1690mm long. If they cut and spliced the wires to accomplish this swap it is likely you will have problems with the connections soon. Your vehicle is equipped with 4 sensors (2 upstream & 2 downstream).
The correct Walker number for the upstream sensors is 250-24395
The correct Walker number for the downstream sensors is 250-24414
