Engine/Transmission (1998.5 - 2002) stumble again

[Agades]

some of you may recall about 6 months ago I had a big problem with a stumble



I had basically cured it by a cummins reflash and a new edge box

My truck worked pretty good until tuesday the stumble showed its ugly face again



now Im going through all the stages of dealing with a problem

- mad

- denial

- finger pointing

- mad

- extremely high phone bills

- mad

- emptying pocket book for new parts

- wife threatens devorce

- mad



you get the picture

engine stumble

When does this occur? Before changing the stock lift pump on my truck it stumbled above 2,800 rpm. after changing the pump I can go right up to red line without a miss! check you fuel pressure out of the fuel filter.
