Welcome to the site. It may be your throttle body but I will move this thread to the third generation Ram section,

My truck does the same thing on start up it idles at 1300-1400 then slowly crawls down to 500-600. I don't think its anything to worry about.

 

It shoots gas into the cylinders till it fires over. Once it knows it is running it adjusts the idle. Nothing to worry about.
