Engine sputtering.... please help!

[sbizallion]

My engine is sputtering and cutting out under moderate acceletation. I have an 05 cummins with the 5. 9. It does not always do it... about every third day or so and only at freeway speeds.



I have an aux. pusher fuel pump with a low pressure warning light and its not indicating a low fuel situation and it doesn't do it under hard excelleration.



My x-power programmer gave me a code which says cylinders 4-6 are shorted high or low. Anyone know what this means?

sounds like injectors going out. If nothing else dump some power service and drive it hard. if that doesn't work then its time to do the injectors.

do know what "cylinders beeing shorted high or low" refers to?

Probably either wiring or a shorted solenoid...
