my car has been bucking and misfiring of late...finally got it checked out by nissan dealership...find out my #4 injector is going bad and my o2 sensor has gone awry. i am going to order a sensor from oxygensenors.com, but i am wondering what else do i need to install it? i thought i was reading somewhere that i need to cover part of the sensor in some substance before i connect, any truth to this?

i am also looking for a good deal for a fuel injector, does anyone know any good sites or stores i should can find a quality one for a decent price?
thanks

 

Just go to Courtesy Nissan and get a factory O2 sensor. The only thing I can think of to put on the sensor would actually go on the connector, some electro gel (whatever). You can get it at Auto Zone to help insure good signal at the harness and prevent against moisture corroding/interfering with the plug. Anyone else?

 

You can put anti-seize grease on the threads of the sensor to make it screw in easier. DO NOT PUT ANY GREASE ON THE SENSOR ITSELF, or the sensor will not work properly.

 

If you get the Factory OEM sensor made by Bosch, it will cost just over $110. All you do is unscrew and unplug the old one. Then, you plug and screw in the new one. It's much easier to install if you have the OEM sensor.

If you go with one of the universal sensors at Auto Zone, you will have the splice each one of the three wires. Then, heat shrink the connections. If you are good at this kind of stuff, I say save the $50 and get the universal sensor. I bought the OEM sensor made by Bosch and it took me less than 5 minutes to jack the car up and unplug the old sensor and hook up the new one.

Oh yeah, put anti-seize on your o2 sensor threads. And don't touch the sensor part with your hands. The oil off your hands could throw off the reading. I followed my Chilton's Manual. It told me all I needed to know combined with the directions on the sensor's box.
