it turns out that i have 2 bad o2 sensors, one i think is bank 1 sensor 1, and bank 1 sensor 2......... i can clarify tomorrow. anyway, is there a way to replace them myself? each sensor i think is about 100, and so i dun wanna spend extra paying someone to install them if its not that hard.

 

I would also like to know if there is a write up I dont know about

 

the hardness of the sensor is located on top of the front exhuast manifold. you can take off the sensor and follow the wire to the hardness and disconnect the hardness. you will need pliers to remove the clip that holds the wire and a O2 sensor socket to remove the O2 sensor.

dont for get to apply some antiseize to the new plug's thread before you put it back.


good luck.
