I just swapped a 95 B18C1 into a 92 Hatch, and I'm getting a CEL #43..and the gas mileage is pretty bad..I used the O2 sensor from the 92 Dx..is that not compatible with the Integra ECU? Please help me figure this out before I waste tons of money on a new O2 sensor. Thanks alot,

come on guys, someone's got to know waht to do!!

 

If it's a 4-wire O2, it should be good to go. Some people say you can't use rear(cat) Honda O2's in the front position, and visa versa, but I've done so with no problems whatsoever. Of course both your car and your swap engine are OBD-I, so you don't even have to worry about that. You might want to check if you have a short or any other wiring problems anywhere. You might also want to see if your O2 has an excessive amount of gunk built up on it. If so, you can usually heat them up with a torch until they're hot and it'll burn off all the gunk, and the O2 should be good to go. If all else fails, I have a couple spare Honda 4-wire O2's in my garage.
