i have a 95 gsr i just bought

took to an emission diognostics because i cant figure out why im not passing

my hc are 280 and the limit is 220

well the results came that my o2 sensor isnt switching??
i overlooked my wiring and it was twist tied together. the o2 wiring is the only wiring that has been tampered with


there are 2 brown wires with a black line going into each other and then going to the o2 senser

and the other 3 are fine (tan with black line/ white w. red line/ and green w/ blue line)

i crimpt all the wiring so it wasnt twist tied and replaced the 02 senser w/ one i had in my room and now im throwing a cel

 

maybe the one you put in is bad, you better off getting a new one and puting it in.
