Hey all, so I just received my replacement oxygen sensor in the mail today. While I was working on my car, I noticed that the upstream sensor is really stuck. So far all I've done is applied rust spray on it & it BARELY moved it. Currently I'm using one of those oxygen sensor sockets that I got from Harbor Freight, but I'm not getting much success on that. I'm considering going to Harbor Freight to get myself a 22mm wrench (I already have a rubber hammer) that I saw based on a Youtube video as the next possible step in hopes to loosen up this stupid sensor so I can get it replaced. Now in the same video talked about heating up the sensor and I was wondering if I could drive the car around a little in order to hopefully heat up the sensor enough to get it replaced that way. I've never done this, so I am open to any cost effective solutions (I could take it to my mechanic, but he'll probably charge me around $100 to do this).

Do you have a propane torch, they can reach 2k F. Be easier to get everything set-up with in reach (using eye and hand protection) and heat the bung up with the torch.
It'll cool too fast to have a drive change much.

Agree on the torch. You want to heat the exhaust pipe up relative to the sensor.
Also, after you get the sensor off, use anti-seize on the threads before screwing the sensor back in.

FWIW - Try tightening first, then back to Loosening. I've seen this work, though why it works beats me. Longer wrench, or 18"-24" of 3/4" iron pipe to extend your wrench handle and give you more leverage.

Cut the wires off and put a deep socket on it or use the box end of a wrench. High torque on either the open end wrench or the oxygen sensor socket will spread and round it.
So here's a weird small update; for some weird reason the check engine light actually went off on its own. The engine is actually sounding fine again. However, as a preventative measure I'm gonna go ahead & replace the o2 sensor & put anti-seize on it to ensure that this doesn't happen again.
Yes on torch and longer leaver/extension pipe to get better torque. If this is under the car and jacked up, make sure the car is secure with backup jack stands and wheel chock before you start yanking around.
