fueling ?

[jl99cummins]

Guys, I am curious as to why/what is causing my truck to cut out for a second while I am in od locked. It only does this in od locked (fuel pressure at 14psi and the edge box at either turned up or down). Acts like a miss or fuel is shut off again this is for a split second. Is this pump shudder? Does this after you hit above 2000 rpms. It clears up also after the split second causes me to lift. I am puzzled just trying to find a answer. Maybe someone has had this happen to them before. Forgot to mention i have a set of scheid injectors. Thanks

My truck is doing it right now also. But I have the check engine light on and it says map sensor low voltage, and iat sensor low voltage. I replaced both sensors and can't remove the CEL. And the truck still has a split second miss. I dropped it off with Jeff Garmon on Sunday to check it out and also check the TC and trans temp light and OD off light, and etc...
