This is all the more interesting given that oxygen sensors rely on reference air, which they receive via the supply wires. Therefore, the supply wires must not be soldered. At least, that is my understanding. I used to be a huge fan of soldering, but with the right tools, you can achieve excellent results with crimping. When measuring the resistance afterwards you can rule out a bad connection.
But I don’t want to hijack the thread either ;-)
