Another Monday is here. What no cheers? Ok. So I had my car inspected today so I can renew the registration. No problems there, but that was after the five hours I spent yesterday replacing the downstream O2 sensor. That was so much fun! Squueee!!!! The engine side connector for the sensor on the main wiring harness totally came apart. I think this was my problem in the first place as I saw two of the wires were already split and the other two split when I was unplugging the sensor. That was a fun time unwiring everything, splicing and soldering the new sensor directly into the harness. Probably should have done something better, but oh well.
