could have come missboxed from the parts store! It does happen.

 

yeah i need to check out another auto parts store. hopfully it was just a misboxed issue. thanks. As to wilderness' question, i dont think they have four. just on the passengerside follow the exhaust and you find one tucked way up there b4 the cat and then almost immediatly after the cat as well.

 

What is the best way to unclip the o2 sensor wire connector (OE version)? I have managed the post cat one, but I need to know if there are any tricks so I can master the pre cat sensor.
