assuming 6.0?

change out the fuel pressure regulator on the fuel rail yet? with 199k i would guess its time for a one of those. I have 192k on my 2003 2500HD and its starting to do some of those same things you describe, STARTING to do those things. its also once in a great while hard to start and wont idle for **** right after starting. I am 99.999% certain this is my problem. its a 60$ part at oreileys but i bet you could find em for cheap(er) elsewhere. and is an ALMOST tool-less job.

just a thought. maybe someone else can contribute their opinion?
