Do I need that o2 sensor

[maxman]

Noticed something the other day...

My '82 EURO (CIS) does not have an o2 sensor. It looks like a PO removed it. There's a spot for it in the fake cat, but no sensor, just a plug. Car runs good. Hunts a bit at cold idle, but I'm told this comes with the territory.

Let a sleeping dog lie?

[Oh Haha]

The Euro spec 911s of that year didn't have an 02 sensor. The PO probably replaced the cat with an aftermarket version that has the bung.
