I have an '04 F250 with the 6.0 About 2 years and 45,000 miles ago I installed a set of pensacola diesel 40hp injectors with all the usual goodies. This summer I installed a Swamps billet FICM with the 58v mod and the 50hp flash tune. My truck has 206,xxx on it. The truck runs a bit rough til its completely warm. When its real cold the truck will lope moderately and run a bit off. Once its warm all symptoms disappear after 5-10 minutes and the truck reaches running temperature. The truck will also slightly buck or miss in higher gears at low rpms under load. Its most evident in 4th or 5th at 1500-1800 rpm when givin her some pedal it will miss or buck a bit. I've done fuel filters every 7,500-10,000 miles since I've bought the truck, never run sketchy diesel in it, and always run some sort of an additive. I'm looking for some insight on what this could be causing this problem.
I have no check engine lights, no blue or white smoke, and no other symptoms other than the running issues.
Things I'm thinking it could be?
-An injector or two out (I now see pensacola has a hit and miss reputation)
My scanner doesnt data-log so I would probably have to pay the stealership to look and see if I have an injector on the fritz
-Fuel pressure regulator
I guess theres a list of things that could be causing these symptoms.
I'm just looking to see if theres anybody whos run up against these symptoms at all... or some advice as to what steps you would take to go diagnosing this.
I'm a college kid with relatively limited funds and a good deal of technical know-how so I'd like to avoid the dealer if possible.
Also, can anybody recommend a good fuel pressure gauge (the service technician type not the a-pillar mounted kind
) I believe that should be one of the first thing I should start with and see if im ever dropping below that magic 45psi.
Any tips or info would be much appreciated fellas!
