Ok, I found a connector that looks just like the connector on the passenger side, and it has the same label on it (608), and it looks as if it comes from the o2 sensor, but it's already plugged into something.

That looks exactly like the same connector on the other side, but it looks like its plugged into something down there. Is this what is supposed to be plugged into the o2 sensor connector?

 

You should try to pull that up, cause there is nothing to plug into down there, all the connections for the 02 sensors are on the firewall

 

I'll get on that as soon as I can! The weekend is over, and now it's harder to get time in to work on my car. These codes aren't something that will hurt the engine though, right? The bank o2 sensor doesn't do anything other than read values? I don't really know what the air/fuel and speed idle air control codes do, but they don't sound like anything that would screw the engine up....am I correct in assuming this?
