My trucks been acting strange for awhile now. A few months ago it started to buck and ICP would jump 2-300 psi at steady throttle. Thought it was an APP sensor until I monitored it and voltage never fluctuated. It has gradually gotten worse and started stalling when I engage the clutch and ICP was dropping off, I replaced my IPR because it's original and It made all of the symptoms way worse, then I threw in a new ICP sensor because that was also original and it made no difference. Now it stalls more and it doesn't ramp ICP smooth, if I lay into it slowly it will hang around 900 psi, the IPR duty cycle will ramp and try and build pressure then all of a sudden it will spike up to 2500 psi like the valve was hanging up. I was wondering if it was a low pressure oil supply issue but it starts right up after it stalls so the reservoir isn't empty. My gen3 just started leaking all of a sudden and I'm wondering if anyone has any input or has had experience with pumps cutting in and out, because in between events it drives fine.
