Ford 6.0L Power Stroke Diesel :: Engine Idles Rough When Warm - No Codes - Fan Speed 0 Rpm?
Oct 18, 2016
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 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.

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.

As the title says I am suddenly having a long crank when starting and low oil pressure when when warm (above approximately 100 degrees). IPR goes to 85% when cranking. Stored codes were P2290 and P2291. Other symptoms are low power and what sounds like a power steering pump with low oil whine and low power. (It is not power steering related however, I checked.) I pulled the oil filter and cranked engine and filter bowl filled in less than 10 seconds.
Oil did have a fair bit of air bubbles. Oil has 5000 miles and is Motorcraft 10w30 diesel. I have not added any since the last change. I do not have the new style pump so it's not the STC fitting. What my issue is? I do have AE if any other info is required. Particulars are in sig. The searches I have done combined with the mileage I have lead me to either the low pressure pump is failing, or the high pressure pump has lost the ball bearing out of the side.

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.

My 06 currently has 296k miles. 3 years ago I put a lot into her. Dummy plugs, stand pipes, STC, hg,studs, oil cooler, bpd egr cooler. Cleaned spool valves and fresh o rings in injectors. (Alliant) plus a lot more that I can't remember. Ran very very well after all that.
Fast forward to a few weeks ago. Driving down road and truck died as I let off pedal to slow down for turn onto my road. Took about 7-8 tries to get started back up. Icp was reading in the 300's until it finally started. Made it home. Shut it off. And started right back up.
Few days later truck died again same way. Let off to make a turn. Several attempts to restart icp was in the 300's again. Once it started building 420ish it sounded like it was firing a few injectors and slowly started running. The next time it happened the same way but when I got it back running I eased to my inlaws like less than a mile. When I got to their house and pulled in and went to back up to turn around the display on dash said low oil pressure and started missing a little. So once I got home started researching.
A few days ago I pulled out the low pressure oil regulator to check it out. It was clean but did have some mild scaring. I used some fine scotch rite and smooth it out a a little. It moved freely in the bore so I put it back together. Then pulled the oil filter cap off to check the little black valve. I noticed the filter was not dripping with oil like normally when I change the oil. And yes it's motor craft filter and cap. It checked out ok. Press it down and turned engine over and it filled and held. Let off of it and it drained.
Next I air checked the high pressure side. Applied air and waited until I could hear the air (IPR still open) then closed the IPR. Couldn't hear any leaks. Just a very very minor his and couldn't pin point where. So I went ahead and went to dealer and got new stand pipes and plugs. And ordered new print set for injectors. Pulled injectors and didn't see any smoking guns. Replaced prongs, stand pipe and dummy plugs and put it all back together. Cleaned the injector cups and hold down bolt holes. Torqued injectors to spec.
Got it all done and rotate motor by wire next to heater blower to assist prime system. Tried to start it up and it took two tries but fired right up and sounded smooth as hell. After it idled a few minutes I saw a haze from exhaust. It smelt just like fuel. A few minutes later started idle a little rough. Gave it some go pedel and it was rougher at about 1600-1800rpms and couldn't feel it above 2k. Got my laptop out with AE and done balance test. Did not show anything. No codes either.

It's an 04 F250 with the 6.0, and has been there about five months now. The backstory I have been given is that it drove in running rough, gave crank position sensor codes, and the CPS was replaced. That was the last time it ran. Since then, it has had the CPS replaced five times, the FICM rebuilt then replaced three times, the engine harness replaced, and spent some time at Ford. It would only show about 30rpm while cranking. The engineer came and looked at it, said it must be the tone ring on the crank and that's it.
Here's where it's at for me: Cranking RPM peaked out at 57, but the fan rpm was about 180 while cranking and it sounded like it was cranking pretty quick. I disconnected the glow plug module, had another guy crank it while I gave it a quick shot of starting fluid, which it caught and started to run on. It sounded like it was running on fuel for a second, then shut back off and now cranks unevenly.
According to the owner this thing has seen lots of starting fluid in the course of diagnosing it, and there were no odd noises before it shut down so I suspect stuck valves from sitting so long. It did give me a whole bunch of codes which I will post tomorrow, including injector #4 high. I tried to do a buzz test but just got a message saying "unknown code, please wait" and then nothing.

I have a 2005 f350 6.0 power stroke. I had a crank no start when hot issue. I bought an obd scanner with the torque app. IPR was at 85%. ICP pressure was low. I got the IPR out and bought a new screen because it was clogged. Upon putting in I broke the injector female side plastic connection.I bought the injector connector piece and installed it. After putting everything back together it starts but runs very rough,low power. The IPR was fixed. ICP,ipr and ficm are at good levels now.
IPR=14.7%-30%
Fcim sync=1.0
Fcim voltage=48.5
ICP pressure (idle)650-850psi
My fault codes are:
P0672 (glowplug)
P0674 (glowplug)
P0678 (glowplug).
Why it would be running/idle rough?

I have recently developed this problem with my 2005 F250 6.0L with 86,000 miles and don't quite understand it. If I drive my truck and then shut it off for a couple minutes, say to go in the store for a few things, when I try to start it back up it won't stay running. It chugs for a couple seconds at real low RPMs (300-400) then just stalls. When I was at the store the first time this happened, I went back in and bought a bottle of starting fluid and gave it a shot, (I know I know, shouldn't do that) and it started right up and got me home.
Thought it was a fluke as the next time I went to start it, it fired right up (sat over night). Drove a couple hours then shut it off, it sat for three or four hours. I went to fire it up to go to a wedding shower down the street about 20 minutes drive and it started fine. Shut it off to go in and pay my "respects" and was out in ten to fifteen minutes. Again Chug, Chug, Chug, stall. Tried to start it with the same results about ten times, then I said fine went back in and ate some free food and drinks for a couple hours and came back out and it fired right up again.
I drove home tonight and while in by drive way at home tonight I verified this again. Turned the truck off and tried to start it back up ten minutes after unloading the truck and same thing, no start. What could be the problem? Only other issue I've noticed was a lack of power on take off from a dead stop then a like a switch the power comes on in about three seconds.

My best friend has a 2011 Ford F-250 6.7 ltd power stroke diesel XL. He was driving to Denver in -4 degree weather when all of a sudden his windows iced up and the temperature gage would not sit at normal operating range. ( stayed all the way down on the cool side) the heater seemed to be blowing warm air not hot like it usually does. The thermostat was changed 2 months ago any thoughts on this one?

I have s 2007 f250 superduty with a 6.0. Recently after the engine gets warm I have a problem restarting it. I have to turn the key to the run position until all sounds have stopped then I have to pump the accelerator to get it to start. Sometimes I have to repeat this three or four times before it starts. I have had the fuel pump rebuild and installed two new batteries. What I should be looking at.

I have a may 2003 6.0l f350 4x4 ,autoenginuity scanner, recently bought the truck starts fine and idles well then when engine get warm it starts to smoke unburnt fuel (white) volume of fuel desired on scanner goes from about 14 mm~3 to 27mm~3 and starts to run rough if you depress the acellerator the motor smooths out and the fuel desired goes down. No coolant smell. egr cooler removed ,oil cooler replaced, exhaust back pressure sensor and tube cleaned .ebp sensor koeo 14.2, eo 17 but jumped to 54.0 when map was at 17, bp 31.20 .... The AE is new to me Also found a superchip tuner under the back seat ...

Have a lot more smoke from the tail pipe when they are running their tow tune vs their street tune? For me it seems like a lot especially right now being cold out but I still notice a haze at idle when the engine is warm. Also can smell a difference.
Getting a ficm tuner from php tomorrow so interested to see what that does for things.

I have a 06 f250 king ranch with 6.0 . A few days ago my scangauge showed a code P0405
I changed my egr and after it showed two codes : P0405 and P0404
It still has a hesitation and loss of power , although better than before the Change.

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 have a customer with a 2011 that has a ticking noise that developed into a engine miss with no fault codes. His mileage has dropped from 18 mpg to 14.5 . Heard the noise more pronounced in the left bank. Tonight I disassemble the engine and found the rocker arms by the pivot ball are showing signs of recent wear looks as if they had a die grinder taken to them. The rockers spear loose? The truck has over 100k on it.

I just got a new 2006 E-350 van about 4 months a go (my previous 2004 got scraped - found out the fuel line leaving the secondary filter into the engine with clogged with bits of paper (wtf?)... after I decided salvaged it for parts for my new van...).
New van drives beautifully in the last 4 months without problem, but shut down on me on the highway yesterday. No strange noise or anything when it went out. I managed to coast safely to the side of the highway. Unfortunately, I cannot seem to start the truck again and had it towed home. It cranks, but doesn't start.
I have a scan gauge ii this time and it shows the following:
KOEO:
FICM ~48.5V
ICP 0
IPR 14.8%
Sync 0
Cranking:
FICM ~48.5V
ICP ~8PSI
IPR 84.7%
Sync 1
I still have a P0299 and P2262 check engine code from 2 days previous to the above, but this doesn't seem to be related to the no-start conditioning (both turbo related)
So, pretty much, I'm looking at a very low ICP. Some research indicates this is is due to a bad HPOP, bad STC fitting, or a massive leak. Given the really low ICP, can I rule out the STC fitting and leak? Looks like only the LPOP is providing pressure. Is there anyway to tell if the HPOP is dead or not once I remove it?
Anything I should shot-gun replace first? I have a bunch of salvaged parts from my old van in my garage, which doesn't include the HPOP unfortunately.

I bought a 2011 F-450 with 205,000 Miles on it with a blow engine. Local shop installed a Ford NEW complete engine. Unfortunately we had Code P24A5 EGR Cooler Bypass Control Stuck after the swap. Truck drives fine just has CEL on. Goes to FORD and they test Vacuum from engine, on line, and on compents say all is good. Replace Vacuum switch and Control and neither fix it. Ford stumped and quits responding. So i go get my truck back since they wont respond and had it over 2 weeks.
I get it back and now it has Codes P04DA Closed Loop EGR AT Limit - Flow to high and P1102 Mass Air Flow Sensor in Range but Lower than expected. I also have a P21BO for the reductant level sensor "C" Circuit High.
Since picking it up from Ford, Truck has almost no throttle until oil temperature warms up. I clear codes, truck runs good after warming up and no CEL comes on. Drove it for over an hour. Next key cycle, and CEL is on with all the above codes. Could something be hooked up wrong? Where to start?

I removed the 4 injectors on the drivers side of my 2006 6.0 to clean them up and replace the o-rings and copper compression washer. When I put it all together (everything torqued per shop manual) I am now getting P0266,P0291, and P1000 codes. I have checked the connection on the #2 injector, it is good, and I didn't have any problems with connectors breaking or going back together on the FICM...
The truck will start after a long crank,but smokes and runs rough. It was running without codes before I messed with it. The reason for tearing into It was it has experiencing a pretty big drop in fuel milage. I had been running revx and fuel additives with mixed results...

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.
