hpop pressure ?

[nitrousboys]

does anyone know what the hpop pressure should be at idle?
mine is bouncing all over the place between 325-700 psi.
the default psi that the laptop at the dealership is 745 psi.
when you unplug the icp switch.
I am having problem with a rough idle and missing, its like a random
misfire in a gas motor.It gets alot better when its hot.but when its
cold it sucks.

Have you replaced the camshaft position sensor?

I have not.what problems will i have if that is bad? and how do i check to
see if its bad?there is no codes at all and today I had a diesel tech freind
of mine look at it,at the ford dealership,he plugged a lap top into it and ran
all the tests he could,and found nothing except iractic hpop pressure.
