After 104,000 miles, my "Service Engine Soon" light is coming on intermittantly and I suspect it's the oxygen sensor which has never been replaced. If I can change this myself, I will. I'm having a problem finding it though. This car has a 3.1 V-6. Thanks.

It's most likely on one side of the engine exhaust manifolds. It might be covered with a heat shield. Or if not, it probably would then be towards the center of the exhaust system further down from the engine under the car screwed into the exhaust pipe.
But I would have the engine codes read first to determine what the computer is saying the problem is. Remember that the computer uses the o2 sensor to detect problems, so if the computer indicates that the o2 sensor is detecting a lean or rich condition it's probably another part on the car that would be making the exhaust not meet the requirements of the emission control system. (most auto parts sales people like to sell o2 sensors to people who know nothing about the car because it's easy to convince you that you need one, and for 50 or more dollars it might be worth looking further into the problem)

On any engine the oxygen sensor or sensors are always on the exhaust between the manifold and the cat converter. You have a V6 so you're gonna have two of them. They're easy to spot because they look kinda like a spark plug only with a regular looking wire coming off of it. Dodge Man is right though. Soak them with a penetrant to loosen them.

It sounds like you've an ignition challenge. (track up, wires etc) The o2 sensor is largely a nostril contained in the exhaust device. It smells the gas and tells the computing gadget even if it truly is operating wealthy or lean. you want to ascertain what's causing the priority with the O2 sensor.

Usually between the engine and catalytic convertor.
