3rd gen P0155 o2 code

I've been reading about this, and apparently O2 sensors can be hindered by mud on the wiring. I haven't been able to find any broken wires so I'm going to try cleaning everything.

I couldn't find any broken wires on mine either. I did however unplug and plug it back in idk if reseating it had any affect on it, but i drove it for about another day. Maybe 70 miles, then the next day the ses light was off...

It looks like my bank 1 sensor fixed itself. I replaced the downstream bank 2 sensor and still have no O2 related codes after 1000 miles of driving.

I still have the P0507, fast idle, error.

I am the last person who should post an automotive tutorial but O2 sensors are pretty easy to replace. The hard part is figuring out which one to buy.
