Unless you have a set of torches then you will never get them out. Also when you pull them out they will usually take the threads with them unless you can get it really hot.
No, the spark plugs and O2 sensor are totally different things. that is not right!! they are the same things!!
To change an O2 sensor you need to disconnect the wiring harness from the sensor. Use an O2 sensor socket and ratchet set to remove the old sensor and replace with the new one.

Lambda is o2 sensor in exhaust pipe.
You will have the check engine light on. Oxygen sensors throw very specific codes. Basically you need to use an error code reader. I did and it said the o2 sensor, in my Volvo 2001 s40 has two of them and I need to know which one to change?
1995 vehicles did not have post cat o2 sensors.
It is your 2nd (Bank 2) O2 sensor.
The oxygen sensor is screwed into the exhaust manifold on the rear of the engine on a 1995 Chrysler Town and Country.
4 wires, the black ones are the O2 heater (on the sensor side), the white and green are the O2 sensor itself
It is probably a faulty O2 sensor. But check O2 sensor wiring and connections for damage first.
The bad one.
