When IPR problems occur you have a hard start condition when the truck is warm.... OR it stalls every now and then ... you need to monitor the HPOP pressure with a scanner and see what it does when you step on the pedal etc . etc. I fthe response is linear it is ussually another issue if the pressures are all over the place ussuallly the IPR needs o-rings or the tin piece of crap on the end is loose....
