Likely a dirty lead/corroded connection or dirty ground. Maybe the sensor itself but check the cheap first. Might also be an issue with the gauge as well (a weak solder in my cluster would make my voltage meter dip down to near zero and then come back to life when tapped. Re-soldered the lead and no other issues since.)

for what its worth, my first 164l exhibited erratic electrical episodes, especially the tail lights. After reading a few comments on the BB, one sunny Saturday, starting from the trunk, and ending with under the hood, all relays and connections that I could lay my hands on were cleaned with deoxit and dialectic grease applied. connections opened and closed a few times. I would say at this point that all the symptoms disappeared for the time I had the car. The 164LS, was not as bad, still, I went through it same way. in doing so, I found a couple of bad ground connections at chassis and a starter ground cable about to give up. If I were to buy another 164 tomorrow, before making any assumptions or overloading grey matter, would start at the back and work to the front. Best bang for saving my buck.

Loaded a video on youtube...trying to find the cause for a slight knocking or thumping sound from the engine area. Engine is warmed up after a 30 minute drive. Oil pressure and temp normal. I tried to locate with a stethoscope from the bottom end but nothing different from side to side under the oil pan. Left side of engine vibrates slightly so wondering if a weak mount is causing something to rub something else. Right-front mount is poly. The rest are stock. Video is topsy turvy (new phone...)
You can hear it better after 24 seconds in.

My what a big used OEM 164S cat converter I have gotten for my Alfa Romeo 164S. Pretty hard to find a usable OEM one now for a 1991 Alfa.

I had to cut off 12 rusted bolts to get the 2 inlet and 2 outlet flanges off both ends from the engine down pipes and center muffler as PO of cat had cut the 4 pipes off at all 4 flanges. It took me about 6 blades in my Dewalt Sawzall and air hammer to knock the bolt shanks out. The O2 sensor came out easy with sensor removal tool and cheater bar.

I can't post new pix now as I am having a drop box and computer issue, I can't even download any to my computer. I R IT challenged.

Drove the 91S to the hardware store, and out of curiosity felt the wheels all around after the drive. Brakes were working, but the pedal started rising, so thought I better do some checking.

Sure enough, the RF and LR wheels were a lot warmer than the LF and RR. This was telling me that one circuit of the braking system was starting to partially engage the brakes. Well, rats, didn't need this. Not enthused about putting in a new master cylinder at this time. Too many chores and honey-do items scheduled. Maybe I can still talk Carlo into doing it.

"is the 91s driven regularly?"

It's a true daily driver, used pretty much every day since I bought it in 94. 192k miles now. It gets used for everything, mostly short trips to work, when I worked, lol, to the grocery stores, big box building supply stores, you name it. I haul everything in it, groceries, lumber, concrete blocks, bags of soil or manure, bushes, small trees, whatever. A fantastic workhorse through the decades.

Guess I'll get to change the brake master for the first time. Carlo did the last one back ~90k miles ago.

Having just done mine I can tell you stubby wrenches are very helpful for the drivers side nut.

If you're careful and pre-bleed the master cylinder, you can replace it without having to bleed the whole system. A mechanics syringe helps make sure all the air is out of the MC.

I did this a few years ago and it worked great.

nice!, wonder if a fluid transfusion would work? or is it a good idea just to change it out and be good for another few decades?

I strongly suspect that a seal for one of the two circuits is leaking, so just changing the fluid wouldn't do it. If Carlo doesn't want to change it (since I've trusted his work more than mine), I'll just do it myself. Have worked on these cars for years, but after a few years, the excitement fades, lol; however, I have all of the tools and Steve's write-ups, so shouldn't be a problem, just difficult to actually start to dive in, alas. Always been like that.

I'm sure just replacing it is the best way to go instead of throwing new seals into the old cylinder.

Ive re-entered the ranks of operational 164 owners. Now, just have to drive it 850 miles home! Or at least 650...as my AAA card is good for a 200 mile tow.
