having problems with 5.9L surge and rough idle

[christopher10]

My name is Chris, I have a 2004 Dodge Ram 3500. 160,000mi, auto 4X4.
I'm currently having problems with my truck with rough idle as soon as i crank it up to the time i'm pulling out of drive.
I have a rough idle at a cold start, as i have the same thing even after the truck has been warm. When i'm driving from 0-40mph i can feel the engine surge like it's not getting fuel, and when i come to a stop it starts to to bogg down like it's going to die then rev up and take off like a car at a drag strip.
I have changed the fuel filter and did not pinch the O-ring and have changed the filter, I have ran lucas injector clean through it but it still does the same thing.
I have read it could be the lift pump, could be the injection pump, could be injection problem. I took it to dodge and of course it has been doing this the past 2 days but when i went there it didn't do it.

Could anyone have any clues on this issue? I read to run and idle engine and and open the water drain on the fuel seperator, i'm going to try that tomorrow.

But before i take it back to dodge and they charge me again i hope it's something that i can fix or test my self before paying a huge bill

We seem to be haveing a similar issue, I am just getting started on troubleshooting this issue. Please contnue to post if you have narrowed it down

have you checked the computer codes yet? Both are running electronic injection not mechanical fuel systems. So you should be able to find it through the computer if they don't have a direct fuel issue like a filter

As was already mentioned, check for codes. When its running rough, what color smoke is coming from the exhaust, if any? Our 04.5 work truck had the symptoms you describe, run rough on start up, tons of grey smoke. Ended up being an injector issue, they are not cheap either. The common rail trucks have a poor fuel filtration system from the factory, highly recommended that you put an after market lift pump such as an Airdog or a Fass on your truck for the added filtration and lift pump reliability.

Because of the extremly high injection pressures, it makes the injectors really sensitive to foreign material on the CR trucks.
