There was oil in the front passenger O2. I tried my best to get as much out with a cloth. Any suggestions on what to clean it with? I really hate the idea of putting water/degreaser on it since its electrical wires.

 

There is an aerosol electric cleaner, I use brake clean (also an aerosol) because I have a lot of it sitting around. Something that will cut grease and evaporate quickly (so it doesn't have time to eat the plastic) Just spray it into the connector, shake out the excess and blow dry (if you have a compressor, or let it air dry). Make sure all the connectors are completely plugged in (you will hear a "click")

 

I took brake cleaner to the front passenger O2 sensor clip. Not only was it full of oil it wasn't all the way plunged in. That could certainly be part of my issue.

 

I have been able to eliminate the one code.. I'm replacing both bank 1 sensor 1 and bank 1 sensor 2 o2 sensors tomorrow. I did pull out one of the wires for the bank 2 sensor 2 plug on the wire harness because I didn't realize how it "clipped" in. That could be an issue?!
