Miss at idle when warm
 

I have an 02 24 valve that has a consistent misfire at idle when in park and warmed up. Fuel pressure bounces between 19-21 psi when it's missing. All I know about the engine is that its fire ringed, 200hp injectors, 66mm turbo, ats exhaust manifold, with an AirDog II lift pump...im sure im forgetting some things. It idles fine on cold start up with only a little hesitation at low speeds under light throttle but after a few miles the throttle response is back. No check engine light, no dead pedal. Any ideas guys? Im totally new to the world of diesels! Thanks for any help/advice.

I replaced the cam and crank sensor on mine and it went away
