i think i remember seeing something saying you have to wire up the o2 sensor but cant remember my check engine light has been on for a while no matter what o2 sensor i put in the car help and info or a link would be great

 

Do you have a cx chassis. That'd be the only one i believe from the factory that came with a one wire o2 sensor. If you have the dx/lx chassis however then you should have a 4 wire o2 from the factory. When doing the swap you need an extension that moves the harness from the front of the engine to the back down by the cat.

 

i have been swaped for like 2 years lol its the vx shell jw cuz my o2 sensor check engine light has been on for like ever
