Yes O2 sensor should cycle at idle, get you a new Bosch, they should last

Thought so. I'm going to retorque my downpipe tonight after it's had some time to settle in. I'll likely buy a new O2 sensor this weekend to take care of it before taking it to inspection Monday.

Cat is completely gutted... Damn it. The O2 sensor was crossthreaded, thankfully it destroyed the O2 sensor and not the bung. Had to chase out the threads using a spark plug thread chaser, lol. Worked from inside the cat and cleaned up the threads nicely. Tore off everything on the front of the engine again to replace the coolant lines. I officially hate spring clamps on hoses.

Nothing else I've owned has had spring clamps with limiters to prevent you from just cranking them wide open.

Ah, i gotcha then...

...even worse (imho) are VW's newer versions of crimp-on style

It has some of those too, lol. Went out to Wendy's for frosties, and blew up a sparkplug. The electrode fell out and was sitting on the ground strap when I got home.
