The engine will run real rough with no power and will die if at idle for too long.
I had these symptoms about a month ago at around a quarter of a tank so changed changed the fuel filters. It ran fine until two days ago. I just changed the fuel pump and engine oil today. It started and ran maybe 10 minutes before running rough and eventually died. It currently won't start. Batteries are a month old and fully charged.
My car has 222000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
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.
Engine Misfires
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.

01 mustang v6 running rough at idle and drive. Please help. Replaced a bunch, still can’t figure out issue.
ANSWER : This may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear, turning on AC or engaging the brakes). The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses this information to adjust ignition timing and fuel enrichment. When the engine is working hard, intake vacuum drops as the throttle opens wide. The engine takes in more air, which requires more fuel to keep the air/fuel ratio in balance. When the computer reads a heavy load signal from the MAP sensor, it adjusts the fuel mixture to slightly more rich than normal so the engine can produce more power. The computer will then retard (back off) ignition timing slightly to prevent detonation that can damage the engine and decrease performance. This may also be caused by other closely related components such as a dirty or failing mass air-flow sensor, a faulty throttle position sensor or potentially a vacuum leak. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.

ANSWER : The issue you are writing in about is common enough that a specific diagnostic, namely a reduced engine power diagnostic is performed by technicians dispatched by YourMechanic. If you request that diagnostic, the responding certified mechanic will get this issue resolved for you. In your circumstance, the vehicle’s powertrain control module (PCM) has undoubtedly stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:
Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system
If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My 2003 Mazda Tribute stalls in gear, no power, rough idle, not the plugs, oil fouled black, clean maf and idle air valve
ANSWER : Hello. I would start by scanning the vehicle for codes and checking to see if all of the sensors are reading correctly. If everything looks good then chances are it needs a new computer. I have seen the computers fail on these vehicles over and over again causing the ignition circuits to not work correctly which causes the vehicle to run just like this. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the vehicle is running like this] https://www.yourmechanic.com/services/car-idle-is-rough-inspection
Im getting 2 codes p1132 and p1152 why would they be on and why does my suv have trouble running when the engine is cold
ANSWER : Codes p1132 and P1152 have to do with the oxygen sensor circuits. The engine control unit relies on the oxygen sensors – along with many others – to read the air/fuel content of the exhaust. By measuring the air/fuel content in the exhaust, the ecu will adjust the furl mixture. If one or more oxygen sensors are faulty, the engine will run poorly, can stall, and fuel consumption will go up and power reduced. On a cold start, the engine requires more fuel (rich fuel mixture) to start and run properly until it’s warmed up. A lean fuel mixture when cold, will make the engine run poorly and stall, particularly when cold.
Have a certified technician look into the stalling on cold start to isolate the exact cause.
The truck intermittently, has a very rough idle, and runs rough,usually after warming up.
ANSWER : Hello. This can be caused by a number of different things. If this occurred right after you had gotten fuel then I would start by testing the fuel pressure. I would do this when the vehicle starts running poorly. It is possible that the bad fuel contaminated the fuel pump and it is not putting out the right pressure. If the fuel pressure is fine then I would check the other sensors readings with a scan tool. One other common thing that I have seen on this engine is a leaking intake manifold gasket. It starts leaking on the bottom side and that leak causes the MAF and MAP to not read correctly which causes it to run like this. If you would like to have this rough running condition looked at, consider having a YourMechanic certified techniciancan come to your home or office to diagnose why it is running rough.
Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.
After replacing the power steering pump there was a low idle, idle screw is all out, running rich, and idle speed doesn’t change.
ANSWER : Hi there. The engine has a vacuum leak and is causing the engine to stumble down on the idle. Check all of the vacuum hoses and the brake booster for any leaks. The engine is rich for it’s not burning all of the fuel properly and may also have bad spark plugs. If you need further assistance with engine not adjusting the idle, then seek out a professional, such as one from Your Mechanic, to help you.
