I was wondering what others with a little more experience might think. Also, Does anyone know where it's located, what it looks like and is it serviceable or do I need a new one? Thanks in advance for the help.

Its in-line with the butterfly valve, which your throttle cables are connected to. You can test it using a multi-meter to see if the resistance values are off before committing to buying a new one. The procedure is in the online service manual, you can find the link to it in my signature, or there may be a HOW-TO in that section of this site.
