My truck ('01 FL) with the 12.7 Litre Detroit does the same thing. What I've always done is to kick the idle up from 800 to about 1050. That seems to smooth it out and after a while, I can usually let it drop back to 800 and it will run smooth.

I was at a FL dealer last week and asked one of the techs about it and he told that many times you could have the software on the ECM updated with the latest version and that would stop it. Kind of like updating the operating system on your pc.
