I have an OBD1 engine and i need a new O2 sensor(been running real rich and now its glazed) I have some friends that work at a junkyard and they got me the o2 from and OBD2 car that came out of the cat. my engine is OBD1 like i already mentioned and the o2 i need is the one for the header or manifold. Are all 4 wire o2's the same or do i need to get the correct one for the header....

 

not sure dood...denso makes a nice o2 sensor

 

most 4 wires o2's are the same. im not too sure about obd 2 since they have two. so try to get the primary o2 "the one towards the front of the cat" because i hear the second o2 is different.
