O2 Sensor Flange Welded!!
Okay so my 22re 89 4runner could use an 02 sensor.. i noticed the one on there is a universal (hack crimp job) and looks older then dirt.... So i ordered one from sparkplugs.com (200bucks canadian when all was said and done..) direct fit oem denso..... got it today and went down there to install it expecting to have 2 bolts to take off.... well upon further inspection the universal one on there appears to be a thread on (havent been successful removing it yet) and its threaded into a big welded on flange (right before cat)....
anyone come across something so stupid??? any ideas?? I assume ill have to do sum chopping and welding but where do i find a new flange!! any help would be great

that universal "stupid screw in one" is what most are running, and may actually be a better type of sensor.
The stock toyota O2 sensor is a heated 1 wire. If you stick with a universal bung you could go with a 3 wire sensor. And besides you've got a lot more options with the screw in bung type sensor.

Why would that be stupid? Instead of paying $170 for sensor from Toyota somebody paid $35 for aftermarket replacement, $5 for plange and 20minutes of his time with welder. Wasn`t that a mod? LOL
I have two advices for you, one for the future, one for present.
Future one, before you order yourself any expensive part, check for mods.
Present one: leave old sensor in place, just cut off the wire. Go to mufler shop, check for scrap, find correct flange, cut it out then weld in place just near by the old one....

And yes in the future I will check first.. this is my first stock O2 sensor (as universals have been problematic in past vehicles) and i didnt think to thoroughly check things over...
I think ill head to my parts store and buy a small chunk of exhaust pipe and a flange and then cut and weld...

you got an "OEM" 4-wire sensor? I've never seen or heard of a stock Toyota (of that era anyways) O2 sensor that wasn't 1 wire.
And true a bad crimp or soder can lead to ☺☺☺☺ty outcomes, however the same can be said of an join. If a connector is dirty or damaged it can give you problems too. Just means you need to do a good job sodering you connections together.
