2nd, put a scanner on it to get the code it is throwing. That way you'll at least have a starting point. A lot of today's scanner have troubleshooting info in them that will give you tips as to where to start looking for the problem. If you don't have access to a better scanner with troubleshooter info, go to Autozone, they can at least put a generic OBD2 scanner on it to pull a P code.

I already know the code. It`s a bank 1 sensor 1 low voltage code as mentioned above.

I`m probably just going to swap it out and hopefully that will be the end of it. I`ll update you guys when I have done so.

Thanks for all the input guys!
