Hello. Most of the time when this engine runs like this it is because the high pressure oil pressure has fallen off. Most of the time it is from the fitting at the high pressure pump but some of the time it comes from the stand pipe seals leaking. I would need to check the high pressure oil pressure to see if that is the issue. There are other problems that can occur also but this is the most common. If you are thinking of having this inspected, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the rough running issue and advise you on proper repairs.

6.0 Powerstroke Rough Idle Causes
Your engine`s fuel pump pulls the fuel from the tank to the injectors. When the fuel pump clogs or becomes severely dirty, the system will not get enough fuel, causing rough idle, slow acceleration, sputtering or stalling.
The 6.0L Powerstroke is known for having major problems. Most of these problems originate from the factory design. The new EGR emissions system that was introduced to meet emissions standards at the time, is a big contributor to the 6.0s frequent problems.
What Others Are Reading. With proper maintenance, regular use and EGR system and oil cooler remedies, a 6.0L Power Stroke can be made to blow past the 300,000-mile mark with few, if any issues. The engine might need an injector or two along the way, or an EGR valve, but it can done.
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
How to fix it? Cleaning or replacing the fuel filter and adding a fuel injector cleaning treatment to the fuel tank should take care of clogged fuel injectors. If the rough idle persists, it`s time to take your car to an auto repair shop.
with a factory VGT turbocharger, the 6.0 made 325 horsepower and 570-foot pounds of torque which was respectable for the time but not outrageous numbers by any means. Unfortunately, the 6.0 just isn`t known for its power and reliability, it`s really more known for all the problems that it had.
The 6.0L Powerstroke produces 325 horsepower and 560-570 lb/ft of torque depending on model year.
The 6.0L Power Stroke, was used in Ford Super Duty trucks until the 2007 model year but lasted until 2009 in the Ford Econoline vans (model year 2010) and in the Ford Excursion SUVs until after the 2005 models when Ford discontinued Excursion production.
The `03½ to `07 6.0L Power Stroke engines (which were also used in E-Series vans until `09) have terrible reputations for reliability and repair costs among diesel enthusiasts. You`ve no doubt heard the horror stories about blown 6.0L head gaskets, fuel system problems, and turbo failures.
Allow Time to Warm Up the Engine
As a general rule of thumb, if it is below zero degrees Fahrenheit, you should allow your engine up to seven minutes to warm up. If the temperature is between zero and fifty degrees, the warm-up period should be three to five minutes.
6.0L Diesel Suggested Maintenance. Oil and Filter – Oil change service intervals should be completed as indicated by the instrument cluster message center or every 7,500 miles.
While it may seem like a small problem on its own, rough idling is a sign that some part of your engine isn`t working properly. Over time, rough idling can result in poor gas mileage, starting issues and major engine problems.
Perhaps the single most common cause of rough idle comes in the form of a misfiring engine. As you may know, any automotive engine contains multiple cylinders. Each of these cylinders contributes to powering your car by combusting a mixture of gasoline and air.
Dirty Fuel Injectors
When the fuel injector gets dirty from buildup or debris, the flow of fuel is restricted. This can lead to an imbalance in the levels of air and fuel in the engine, which will result in rough idling.
The common causes for rough running in an engine are: Engine miss. Vacuum leak. Dirty fuel injectors.
It`s always a good test to simply take a whiff of the coolant and see if it smells like diesel fuel. Also, take a look at the seal in the coolant cap. If it`s swollen up and looks too big for the hole it`s in, it could be leaking fuel into the coolant.
15W-40 (Above -12) – Ford TSB 05-16-6 states that SAE 15W-40 is acceptable to use in operating temperatures from -12 C (11 F) to -1 C (31 F). SAE 15W-40 is the preferred viscosity if the operating is above -1 C (31 F).
The primary difference between 7.3L and 6.0L injectors is the valve that allows high-pressure oil to enter them. On a 7.3L, it`s a poppet valve (as shown in the diagram above). On a 6.0L, it`s called a spool valve.
fastest 6.0 Powerstroke in the world! Congratulations. to Austin Denny for holding the previous record for two.
`03-`07 6.0L: 475 to 500rwhp.
Even a decade ago, before PCM tuning was anywhere near as refined as it is now, several 6.0L owners proved the 6.0L`s bottom end could withstand 700-rwhp. Today, a lot of serious enthusiasts conclude that the 800 hp 6.0 Power Stroke range gets you into unchartered waters with a 6.0L.
The vehicle can run without an efficiently functioning turbocharger, but it will perform poorly, and your decision could possibly have dramatic repercussions. If the issue is an oil supply or internal component-related problem, complete failure is imminent.
Removing the Turbo on a 6.0 Powerstroke. Before you can clean the Powerstroke turbo, you need to remove it from the vehicle.
One major change between `03 and `04 model engines was the addition of the EGR throttle plate, or EGRTP. Located in the intake manifold, it was designed to reduce manifold pressure so that exhaust gases could flow more freely into the intake manifold.
