O2 sensor dilemma (3.2 w/SW Chip)

While installing a new muffler and a cat bypass, I was not able to remove the O2 sensor from the cat. When I went to unplug the sensor in the engine bay, the connector broke (an apparently common issue). I have a Rallye in 1 week and would not be able to get the part from the Netherlands in time, so it leaves the following questions:
1) Can I just leave the O2 sensor out and wires cut to it until I get back and what impact is this going have on the engine & performance.
2) Is this useable since the wire didn’t separate and can I “repair” for the short term?

The connector to the harness is kind of rubbery. Try to get a small vise grip on it and remove the O2 sensor.

No sure what exact Chip it is, but assuming it still uses the O2 signal, it would only use it during idle and part throttle. As soon as the WOT switch is triggered the O2 signal is not relevant. As long as you are not idling through the rallye you will be fine. ;-)

Steve Wong Chip 91 Octane. Somehow, I think I’ll exceed idling…just a little. ;-)

No long term issues?

There are some that recommend unplugging the O2 sensor with a bypass. I am installing my premuffler later this week, and have it prepped for an O2 sensor and WBO2 to go to an AFR gauge. Ivan is a proponent of removing, since that is essentially the European delivery - no O2 sensor.

I am sure some much smarter than I will chime in, but not sure this will impact you much for now.

If you can get it unplugged without breaking the wire just plug in the new O2 sensor. the broken connector body will not have any effect on performance as long as the electrical portion of the connector is intact. Just give it a wrap of electrical tape to seal out moisture.
