This shop has no idea what that adjustment is, so I may have to source another technician. I do not believe that this is something that I can do myself.

A call to the Dodge dealership let me know that they don't work on anything older than 2005. So I sent an email to the automotive department at my school to see if they'd be able to do this adjustment. I included the pdf from the link that you sent me, Nitrous. Thank you so much for your help.
