5.9 Cummins started getting sluggish a few weeks ago. Put a new lift pump on it and new filter. Sometimes it will run like a scaulded dog like when it was new. Other times, it acts very sluggish again.
I have 17 PSI at the filter at idle. Can't check it at full pull.
Injector pump was replaced several years ago. It is a farm truck, not a souped up hot rod. I have about spent all the money I can on it right now.
Any suggestions?
