Finding Old Google Analytics Code

Hello. I am maintaining a site that I did not create; I also use Google Analytics to track web activity. There are some changes I would like to make to our code, but I am having trouble finding it.

The site is using the Atahualpa theme. I know the Google Analytics code is loading in the header – I checked the source code of our pages. However, when I use WordPress to look through the header.php file I cannot find the GA code. I’ve searched in almost all of the 45 .php templates and had no luck. I’ve used the Developer Console in Google Chrome to learn more about the script’s location, but couldn’t find out anything.

Is there a program or web application that can tell me which WordPress template is launching a specific script?
