O2 Sensor Jail - NOT READY - Problem Solved

I needed a video like this when I started... hopefully it helps with those of you having the same problem. I spent money on O2 Sensors, plugs (needed anyway), coil, wires, gas... etc. If you don't wanna watch it all, the gist is try the battery first. Mine tested fine, but it's ultimately what ended up being the last thing I did before it passed. Good luck.
