    IIRC you have 3. 2 in the exhaust manifolds and one in the cat converter. passenger side one is hell.

        2 wire, so it will cost a lot of monies.

        3.4 ftw.

            make sure you get the ac delcos, bosh ones are cheaper(if i remember right) but theyre junk.

                You have 4, one per manifold, pre AND post cat.

                  BANK1 sensors are the ones that read the air fuel mixture. one for each side of the engine.

                  BANK2 sensor is the one AFTER the catalytic converter and it measures emissions.

                  you have 2 bank 1 sensors. get a sensor removal socket.

                    Should have three Bank 1 sensors, one Bank 2 sensor. Thats how my 97 was. my 95 I don't *think* has 4, but its also a 3.8l with a rewired 3.4l harnass.
