Ford 6.0L Power Stroke Diesel :: 2003 - Idles Very Rough - No Power?
Nov 23, 2011
I've got an 03 f250 superduty and a few weeks ago i was driving home pulled to the side of the road to get a phone call and my truck sounded like it was misfiring and started to shake very rough so i quickly got it home and it barely made it up hills with no power at all, took it to the mechanic and he said it was my wiring harness, so i replaced it and it took weeks to get here and i finally get it in and my truck still seems to be misfiring ad idling very rough, I replaced my oil less then 1000km ago and I've had 2 injectors replaced. I've talked to a few diesel mechs and he recommended to put some hot shots in it.

On Tuesday morning I was watching an auction on my computer and saw a 2003 Ford F350 Super Duty Crew Cab Fx4 with 200K on it. It had an inspection report which is *supposed* to note every cosmetic and mechanical issue. It had nothing listed wrong with it for mechanical. I "won" and for my prize I get a rough-running 6.0 diesel delivered.
I just got off the phone with the transporter who picked it up today and he said there are no check engine lights but it is running rough with no power. So I am having him drop it off at a diesel repair shop.
Hopefully it is just something with the wiring harness but I have a feeling it's got at least a few bad injectors so I am probably screwed.

So I am relatively new to diesel engines! I have a f250 6.0L, that every now and again sputters and idles rough, when the ac is off? Yes I did say off. It's only done this twice, but when I turn the ac on it goes away and runs fantastic. Not sure what could cause this, and think it's a little weird that it's not consistent. Sometimes I run it without ac and it's fine, but this has happened twice now, so I thought it might be worth figuring out.

Like the title says I'm having an issue the past few days where I can't drive this truck more than a few miles before it starts acting up with rough idle at stoplights/sign and sluggish acceleration until it gets over 1200+rpm.
Cold starts fine, drives good till engine warms up to around 130+ECT then it starts acting up. Stumbles on acceleration for little bit and puts out a little black smoke until it gets moving. No check engine light or codes found.
However a month ago I had the check engine light come on with a P0404 & P0405 and it still started & ran/drove great even towing. If I reset the code it would stay off until I restarted the engine the next time. I replaced the Dorman EGR because it had a lifetime warranty and only had 5,000 miles on the first one. The code did not go away until about two weeks ago the light went off on the dash and has never come back but I had not erased the code? So I'm not sure if this is still lingering issue or what.
I was checking my ScangaugeII when I came back home today while the engine was still idling rough and this what I saw for Numbers:
Low idle in Park
ECT 193
EOT 191
FICM 49.0
IPR 21.4
ICP 582
ICV 0.81
V 13.8
TFC 1.91
VSS(fan speed) 0
(This one doesn't seem right in the past is 500 or more rpm from what I remember?) What am I missing to check over?

So this is reason #345 why I should never have let my wife drive my F-350. I am in the Army, and I got a frantic call from my wife (I missed the first 7) saying that the truck died and won't start. I drive all the way to the truck, pop the hood and discover:
1) there is no coolant; and
2) there is no oil (actually just EXTREMELY low on both).
So, I do what any good Soldier does, I push the truck all the way back home (downhill mostly), buy 5 quarts of oil and a jug of 50/50 coolant, fill up both and try to start the engine.
The last time it ran out of oil (small leak on a seal that I didn't know about) in 2006, all I had to do was fill the oil, turn the key, and press the gas until it kicked over (don't judge me, I was a dumb LT). I did this again this time (now, I am a dumb CPT) but now it: 1) idles very rough; and 2) won't start unless I press down on the gas when I turn the key. There is no gauge light when it does this. I read the thread on the UVCH, but I am concerned I might have done something horrible to my truck.

2003 7.3 excursion.. The truck starts every time revs up and idles about 3 seconds then the rpms drop and it tries to stall out catches itself then revs backup and idles rough similar to if you have got air in the fuel lines from changing the fuel filter.. About 1 in five times the truck will stall out and it starts and immediately and idles rough but the rpms and everything runs at speed and rpms don't drop again! This is a reman engine/transmission recently installed.. The mechanic who installed it was unable to figure the problem out.

2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.
I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.
I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.

Problem started 2 days ago, driving around and my truck would stumble and lose power. Give it gas, won't rev up but it cleared and ran fine for a mile or so then it comes back (off and on all the way home). Check engine light didn't come on the first few times, came on a couple times on the way home (maybe 4 mile trip) but goes off when the truck runs fine. Thinking it was maybe the fuel pump (got 140K on the stocker). Talked to a few friends, some thought it was algae build up in the tank that was clogging the filter on the pump, underhood filter changed a couple hundred miles ago. Looked fine with slight brown build up at bottom of bowl when I replaced it.
Ran it around yesterday with a friend of mine and his scan tool hooked up, acted up once, check engine came on for a few seconds and shutoff. No code and for some reason we couldn't get it to live data while driving. I dumped in an algae eater yesterday and left the truck overnight since I had to work. Got home this morning to run her around the block to circulate the eater. Truck started and idled fine, went to pull out and she won't rev up, pumped the gas and NOTHING! Check engine light is on now but don't have a scan tool handy to read it. I heard the truck will store the code?
What this problem might be? What's a good scan tool for our trucks that can live data as well? CPS is good and already did the UVCH mod.

'03 6.0 Powerstroke. Rough idle AFTER it warms up. Runs fine cold. It seems to studder and miss at mid range acceleration. Egr deleted and new oil cooler installed. New lift pump. Replaced ICP sensor. Have 48.5 volts at the FICM. Replaced the fuel pressure spring to the blue one. All new filters. Does not smoke. Does not throw codes. I need to fix this truck one last time. It has a date with the bottem of a very deep lake! It has been nothing but a pos since it hit the ripe old age of 25k miles!

I have '03 6.0 when it gets to full temp it will run horrible and eventually stall. It will take a few long cranks to restart. will drive a little bit but will stall again. It will idle all day long even after a stall. IPR @hot idle is 22 and ICP @hot idle is 640. IPR and IPC readings seem to run good throughout the rpm range except for when it dies. Then the IPR is anywhere from 71 to 85. Has new ICP and Pigtail. Runs very good until hot. I am leaning towards HPOP.

I am working on a 97 4.6 with 146k for a friend. It idles rough and seems to lack power (then again a 4.6 lacks power )
Has New:
plugs
wires
coil packs
fuel filter
sea foam intake
sea foam fuel
I have checked:
proper egr function
vacuum leaks
cleaned IAC
steady 17-18 in vac
clean air filter
cats do not seem to be getting too hot.
no codes
KOEO test ok
KOER test ok
The plugs worked some. Dirty MAF, clogged cats??

My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.

2003 f350 dually. Fully bulletproofed about 10k miles ago. Everything was running great for about 5k miles. A friend of mine got stuck and I went to pull him out. Got him out but got on it really hard...never overheated or anything.
Next day truck throws a cyLinder 5 contribution balance code. Ran ok but idled rough. Pulled injector and put a used one from a running truck in it. Code went away and runing fine for a few weeks. Took a long trip from FL to Texas, and on the way home same code occurred but idle was not as bad. I would clear the code and it would be fine for a few hundred miles, then would show up again. Made it home, still was driving around town a little with the code only showing sometimes. A couple blocks away from home taking off from a stop sign lost all power and motor shut off. Turned out the Injector o ring blew and hydrolocked the motor.
So now, ordered all new 155cc30% injectors , 58v ficm and new oem injector harness. Installed and Drove the truck to Illinois. After about 700 miles I noticed a little rough idle and had a cylinder 4 cont code. Made to Illinois and back to fl. At fl line I had cyld. 4 and 5 codes now. Cleared and cyld 4 was gone but 5 stayed. Got home and balance test showed 4 and 5 bad injectors. Sent them off to be fixed just got them back in. Truck started fine, smooth idle, ran for about 10 miles and cyld 5 code come back and so does the rough idle. I'm at a loss now.
Will be doing compression test tomorrow. Other than a rough idle truck runs flawless, will roast the tires and pull anything hooked to it. No hot starts, no symptoms of anything else. Possibly a problem with the oil rail feed on that cylinder? Main ficm harness? Bent pushrod?

Have a 2004 f250 that is having issues. Once the truck is started the idle goes from normal to loud almost sounds like its going to stall. A few weeks back the same happened when i was on a red light. It choked almost to where it was going to die. I accelerated when light turned green and would not move at all. I had to literally use full throttle to get out the road at about 5 mph. I pulled in to a gas station and fueled up as i had a quarter of diesel left and it stopped the rough idle and power starvation once i started the truck up again. It sees like this time its getting more persistent... FML AND THESE 6.0 problems

I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

I recently bought a 2004 6.0 extended cab truck. It has 223,000 miles on it and has been running great. Bought it here in Arkansas where I live and recently drove it to Texas and back after having just put some Hot Shot oil treatment cleaner in it. I ran it the 1000 miles as it suggests. Just the other day as it was hitting the 1000 mile mark the truck started to lunge/runaway and stalled. I finally got it back home and started looking into the issue. Based on what it was doing, (lunging/running away, and at idle in park random burst of rpms and then dying after doing it a few times), I started to do some research. Most of the answers I found claimed it was the IPR valve. I found that the IPR valve is supposed to, as claimed by some, be pulled and inspected every 100,000 miles are so and if need be replaced or the rebuild kit gotten for it. So I decided to just replace it as well as the oil, oil filter and fuel filters.
When replacing the IPR valve I noticed that it was original and that its screen was missing. I didn't have any problem moving the little piston in the center of the shaft with a small bolt however that doesn't really mean that it isn't bad. I tried a magnet to see if the screen was still in there and nothing came out. I did not try using a camera as I do not currently have one, to look inside the port to see if I saw it. After replacing the IPR valve with a brand new one and changing the oil I started the truck. It seemed to be running a little ruff so I let it warm up. Not one minute later the exact same thing started happening, lunging/running away (random increase and decrease in rpms), so I called it a night. The next morning I decided to change the fuel filters. No that it matters the order in which I did it, but I changed the top end filter first and the the one on the frame with the dealer recommended OEM filters as was the case with the oil. I did find in the filter on the frame that there was a small amount of sand and clay soil looking matter in the filter. I did clean out the filter housing as well.
After replacing the filters I started the truck to warm it up. I noticed that it was still running a little ruff but no random, lunging/running away (random increase and decrease in rpms). However after five minutes it started coming back. I finished letting the truck warm up and took it for a drive. Got it up to between 7-80mph for about 15 miles to try and see if I could "blow out" whatever may be in the fuel if that was even an issue I do not know. The truck seemed to get more power and run a little more smoothly so I stopped at my buddies house not to far from where I was and let it idle. No issues other than a little ruff idle. After about 10min I took off towards home doing similar speeds. I noticed at a little over 2000rpms that the truck was shaking a little but so I dropped the speed down. When I got home not more than one min after idling the same issue, lunging/running away (random increase and decrease in rpms), started happening again.
At this point I took back to the interwebs and came across a post that said the ICP might be bad and does cause this issue, lunging/running away (random increase and decrease in rpms). However I also noticed that this is a huge debate as to whether or not the ICP can cause this. Ford master mechanics say no and other mechanics say yes and round and round it goes. I decided to do the simple test many recommended which was to simply unplug the ICP and see if anything changes. Things did change. No more lunging/running away (random increase and decrease in rpms). Not more than two minutes after plugging it back in, allowing the computer to account for it now, the lunging/running away (random increase and decrease in rpms) came back. In the middle of it doing this I unplugged it and that went away. So needless to say I replaced the ICP and voila the lunging/running away (random increase and decrease in rpms) is gone but the ruff idle is still there along with a slight loss of power.
To answer some questions:
1. The oil and water are not mixing so I am almost positive that the heads are fine
2. The intercooler couplings are leaking a bit. I have ordered the new ones and will replace them as soon as they come in. Can this cause the issue?
3. I am blowing no white or black smoke except for when the lunging/running away (random increase and decrease in rpms) issue was present and the truck almost died. It would knock occasionally when it almost died and would send a slight puff of black smoke which I assume is a low or high fuel issue from the truck trying to die
4. I have not had the no start issue at all
5. I did not see any debris in the oil during the oil change
6. I didn't do the air test on the ICP port as I do not have the adapter.
7. The only code I got on the IBD II port was when I unplugged the ICP which was to be expected
8. I found no damaged wires
I am at the point where I am wanting to take it to ford to have them run a diagnostic on it but am wondering if there is anything else I need to be looking for. Here are a few questions I have.
1. Does this sound like a bad injector? (When I bought the truck it would sound like a misfire or ruff idle condition was present for about 5-15 seconds and then it would smooth out with no issues. It would run a little ruff if you tried to take off without letting it warm up, which I did once or twice and low rpms, but when it warmed up no issues were present).
2. Could this be the HPOP?
3. Could this be the FCIM? (The previous owner had replaced the FCIM not to long ago with one from Ford I believe. Said it cost him something like $700)
4. Could this be something clogging the oil screen under the manifold?
My final question right now is do any of you know where or what brand OBD II reader or software I can get for a decent price that will tell me the voltage of each injector and FCIM is without me having to go to Ford to get it looked at.

My truck died on the way home the other night. After pulling over it started right up but died three more times on the way home. Changed fuel filters, cps sensor which wasn't bad when tested, checked fuel pressure (60 psi), cleaned egr valve, fcim has 48 volts, batteries have 12 volts. Tried unplugging egr valve and icp sensor. Truck will start with icp unplugged . Ipr, stand pipes and dummy plugs were replaced last year when I purchased truck. Truck will run in park fine no issues idled normal, builds rpms and boost. Put it in drive when it gets warm rough idle and dies but starts right back up evertime. When truck doesn't die it has no power.

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.
So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .

I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

Having some problems with an e-350 dying when in gear and rough idle. Truck starts up after it dies. Vehicle acts like it is starving for fuel. I have check fuel pressure after fuel pump and getting 55psi. High oil pressure pump with in normal ranges. Cleaned and checked egr and it was in the closed position. Fuel filters have been changed. Injector buzz test ok.
