to change the back 1 is easy. just unbolt the o2. then push it back threw the grommet. go inside the car on the pass side by the center console. there is a access panel open that. ull see the connector the o2.

clean ur maf sensor+new air filter

then pull out your 02 sensor and use a wire brush to get the shit off it.
