The Stock Injectors have tiny passages in the Pintel that can get plugged solid with Carbon.
You might or might not be able to see that if you pulled one Injector and took a look at the very tip of the Injector to see if the Tiny Hole is open or not.
Also if you pull and Injector and the metal area of the Nozzle that is exposed to combustion is burned/erroded away those Nozzles have been in the Engine a long time.

Thanks D911.....I'll pull the injectors and have a look. So, if the injectors were old and worn, would this cause a louder than normal idle that smoothes out with a small rpm increase?
I'm not worried that something is seriously wrong with the car because it runs and drives so well, but I know what it is supposed to sound like at idle and it just has TOO much of a diesel sound if you know what I'm trying to say. Has me curious about the injectors or other possible causes
Thanks
