Just recently my 03 6.0L started acting up. When driving the rpm's will drop off and it will sputter then when slowing down to make a turn it will die. I repaced the EGR valve and that didn't help. The fuel filters were replaced aprox 6 months ago. Any help will be appreciated thanks!

 

Does it run fine at higher RPMs?

I would open the water bleed off valve and see what kind of debre you get out of that. Are you using Motorcraft or IH filters?

 

I do only use motorcraft filters. The RPM's don't seem to matter high or low.

 

Check the low pressure oil supply, check the plunger return valve at bottom of the oil filter housing to mak sure it is not stuck or broken, you can use a screwdriver to hold the plunger down and crank it over to see if the housing fill with oil properly. If you don't have good low pressure oil flow then i won't be able to supply enough oil to the High Pressure Oil pump. Another thing to try is to unplug the ICP sensor and see if does the same thing, could be as simple as a bad ICP.
