i got a 91 civic coupe with a del sol b16a3.. ive been having a code 43 for a while and i changed my fuel fiter/plugs/ wires/ installed msd and a bunch of other goodies.. lastly its time to change the o2 sensor..

i went to auto zone and they have one for a 93 civic for $80 its oem style but i asked about a 94 del sol (because of my motor) and there 120.. does anyone know the difference in them?

i figured it would b best to get the del sol one since im running the p30 ecu and all that.. once i get this fixed its time to take off the test pipe and throw on a cat and get the car reffed

 

as far as i noe all 4 wire o2 sensors are the same for honda and acura

 

****.. so preetty much i just waisted a extra 40 buxs ahah..

 

im pretty sure they are 4 wire also
you didnt waste the money because you need one for your motor not the car

 

tru.. thats y i bought the del sol one.. i know for sure there both 4 wire.. i look at the pics on there computer and they looks the same but they both had dif. part numbers so i figured something was different

 

i think the only difference in them is ones sohc and dohc that would exlain the part numbers.
