i just replaced my O2 sensor and i used a butt connector instead of soldering it. some people say not to use the butt connector because the O2 sensor runs off of 1 volt and theres enough resistance in the butt connector to make the O2 sensor not work correctly. anyone know for sure?

Aftermarket O2's come with a butt connector and suggest using it in the instruction that come with the O2. The instructions also say <U>where</U> you should make the cut in the wire (of your old O2). It's not only the resistance in the connector, but the wire itself.

I used one of these myself and I noticed the lenght of the wire with the new O2 was shorter than the factory original. Probably to make up for the resistance in the connector a little bit. My Civic's still running and hasn't even given me a code in the past year since I've changed mine, and I'm still getting the same gas mileage. Yours should work to, just tap into the wire in the right place.
