What's this thing?

So I finally bit the bullet and bought my 930- she's in really great shape (photos soon) but I noticed a loose wiring connection when I was looking over the engine compartment. Not sure if it's supposed to be plugged into something- or if it's some type of a diagnostic port. I'm attaching some photos in the hopes that someone might recognize it and be able to tell me where it should be plugged in. It was found laying just under the oil filter/filler neck area and I'm unable to see anything within its' reach where it may have fallen from. I've noticed that the car backfires a lot when decelerating- not sure if that has anything to do with this gizmo or if they do that anyway. Thanks, in advance, for your feedback. -Jay

I believe that is the 02 sensor connector

That's what I said it was until I read that it's over by the oil filter.

If it is the O2 sensor, make sure your CO%/AFR is set correctly.

The backfiring (gargling) on deceleration is normal. Love that sound... music of the 930! Enjoy!

Thats a 02 sensor connector. I have no clue why its on that side of the engine. Yank it.. maybe it was dropped in there. After market headers dont have it on that side either????????

Dont stress....Take the car to a smog inspection place and check your AFR's. Set them @ 2.5% smidgen rich..IMO.

That looks like the oil level sender plug on the 964/993 body, I know that this isnt the application- it could very well have been dropped in there

Could be the plug for the engine lid light, plug it in and see.

O2 sensor it is! Thanks everyone for the responses- she's in the shop now for fluids change and alignment- I'll have them check CO/AFR while she's there. Found out the car has SC cams and some other mods so my guess is the unplugged O2 sensor was intentional.
