IPR, injection pressure regulator, please help

what are the symptoms of this failing?

my trucks idle is fluctuating, and it's starting to buck a little under acceleration.

Straight from dieselmann's site:

No/hard start hot or after stalling, usually re-starts after cool-down; Jerky, irratic idle; Possible DTC#'s P1211, P1212, P1283:
Usually caused by low injection oil pressure or regulator (IPR) valve. High pressure oil is used to pressurize and inject the fuel into the cylinders--each injector is essentially its own injection pump. The IPR is a by-pass valve that controls the high oil pressure depending on demand.

ok, would those symptoms point to ICP, IPR, or IDM?

Don't count out that it could be the CPS. Unless you changed it recently.
