tech question on 2005 Chrysler Pacifica

what would make my pacifica spit and sputter bad at 35000 rpms

Asked by for the 2005 Chrysler Pacifica
I am assuming you meant to say 3500 rpms. Has your Check Engine (MIL) light come on? Does this happen with partial throttle (light acceleration), or heavy acceleration? Is the engine cold or fully warmed up? You might consider taking it to a shop for diagnosis. This symptom can be caused by any number of things.
