Can I splice a new connector onto an O2 sensor?
Last time I went to the track, one of my O2 connections came undone without me knowing. All of a sudden the car wouldn't idle but my car has always had idle problems so I didn't think anything of it. The next day, I looked under the car and the O2 sensor was unplugged and had been dragging on the road for about 300 miles. Needless to say the connector was fubared.
I switched out the sensor with one of my old ones and it runs decent now but still not as good as it should. I'm guessing the reason I took this O2 sensor out in the 1st place was because it wasn't working too great.
So I'm wondering, can I take the connector off this sensor and splice it in the other sensor? Is there any issues in doing this?

I believe that the wires are steel, not copper, thus the preferred crimp connection. The O2s also get their oxygen reference through the wires (space between the strands, actually) so the convential wisdom is not to attempt a splice. That said, I left a 1/2 inch gap between the insulation and the crimp the last time I did one, and it seemed to work fine, at least it was still working when I sold the car with 30K kilometers on the crimp.
