Ford 6.0L Power Stroke Diesel :: 2005 - Rough Idle - Codes P0672 / P0674 / P0678
Apr 29, 2016
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?

2005 PSD Ex. 4x4.
Drove it a few nights ago and it felt really gutless. Next morning, no start. Well, it tried, but it sounded like it was run out of fuel (had half a tank)and I turned it off. Changed both fuel filters, key on / key off to purge system about 2 dozen times. Still no start.
I have all eight injectors with "injector Circuit Low" code, a P0401 - Exhaust Gas ReCir Flow Insufficient Detected, and P0672 - Glow Plug #2 (which it has had for a few months).
I thought with all of the injectors, it might be the FICM, checked the FICM voltage with Torque during a start and it showed 47V the whole time.
Harness? I did not think running with the glow plug error would be a big deal especially during the summer in So Cal.

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.

My truck is a 2005 f350 6.0, all stock except for an egr delete and 4 inch cat back exhaust. I recently did an oil cooler replacement and egr delete, resealed all 8 injectors, and fixed some wire chaffing at the FICM. it's running great with the exception of idling. It seems like it's idling low but the gauge stays at 750. If I hit the high idle switch, it does fine. Red lights are stressful because it shakes and sounds like it's going to die but never does. I'm posting screenshots of my Torque pro.
I have a SC2 as well but I honestly like Torque better so that's what I use most. I know my ICP is low, but 8 don't know why. No oil in the connector, and no change when I unplug it. The ICP sensor may be a month old with 1000 miles on it. This was taken at a hot startup, sitting in park. When i say hot, I mean I had driven about 60 miles. This is sitting still in drive. ICP voltage finally climbs over 1.0 when i get going about 15mph at around 1250 rpm. The second pic the ICPV is actually higher than normal. It usually stays at .8 until I give it gas.

A while back my 05' f350 6.0 was having rough starts and an erratic idle. It died coming up to a stop sign it started back up after 2 cranks and then it did that same on the way home. The next day leaving work it wouldn't start. I knew i had a couple injectors on the way out so i decided it was time to replace all 8 upon tearing it down i noticed my oil cooler was leaking so i figured it was time to rebuild that and finally do the egr delete that i had been wanting to do. well i put it all back together and got a no start.
The dash gauge on my oil pressure is reading normal when i cranked it so i went and bought a scangauge2 to read the icp its hitting 1500psi when i crank it. The ipr% is reading good. But my ficm main power is at 26v with the key on then it drop to 14v while cranking and eventually down to about 9v. Its never at the 48v that its suppose to be at. The scan gauge is also showing that my ficm sync=0. Would the sync be showing 0 since the ficm is bad? My batteries are fully charged and i have both of them on the charger while I am cranking it.

Pulled p0678, glow plug 8. I've changed out the glow plug on cylinder 1 a few years ago.
Cylinder 8, being on the driver side rear, is it difficult to change out? Should I just pay Ford or another shop to fix this?

Rough idle I have had for little bit.Would stall out at idle or a stop, but fire right up? No one could figure it out with the stalling, but now its bad, started yesterday. Have white/blueish smoke sometimes, ( white smoke smells fuel) on restart after warmed when it dies, first time it took 25 mins to restart, now only takes 5 to 15 mins, when I step on it INCREDIBLE full power, fuel mileage gone to hell also since yesterday. Had full tank, now 1/2 tank.
No problems on cold start at all, no check light, 325,000 and never had this before.
Bad fuel?
ICP?
FICM?
Recent work, new turbo, ( turbo was original turbo installed when built) cooling line to waterpump, oil change, new fuel filters, front brakes and 2 new batteries.

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.

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?

Ok so I have a 2005 f250 6.0L. It is fully bulletproofed with ARP head studs. I am running a sct anarchy on street tune. My problem is that sometimes it is "puking" coolant from the degas bottle but only a drop every now and then around the cap; it drives fine, no trouble codes, the engine and trans temp is fine and it's not blowing white smoke it still blows black smoke, and there is no coolant smell just straight diesel. What might be causing it to puke a drop of coolant every now and then?

This isn't my truck, but I'm trying to diagnose it for a friend and I haven't seen it. He's scanning it with a high-end Matco scanner so I'm not convinced that the scanner is reading right but here's what I've got:
P0056 (2), P0161, and P0300 (random misfire detected). The first two are "gasser" codes and don't show up in the 6.0 bible code list so I'm wondering if they were added in to some of the later flashes??
The truck has a "new" OEM turbo and won't build over 18 psi of boost but, according to the owner, who is a decent mechanic, it's absolutely clean inside. Looking for about the weird codes it's throwing?
All my years of information on 6.0's was stolen with my laptop last year ....

My IPR value on torque pro koeo is at 14.7. Is that normal? Usually idles around 23.7-24 but when I experience a slight rough idle IPR will be 26-27. When I was under the truck last week I did see there's been oil leaking somewhere seems leaving evidence on the drivers side rear of bellhousing. Any relation?

I have a problem with my 2005 F250 6.0 with about 156,000 give or take. Started having a problem a few weeks ago started missing and fuel mileage went south and had it scanned. Codes pulled was P0279 and P0281, I was told probably #7 injector bad so I replaced it cleared the codes and Cranked right up no problems until a few moments later the truck started acting up again. Run smooth than rough idle, smooth, rough idle. Same codes! Tested the FICM while on the truck, it showed like 47.5 volts before cranking and 48 volts when cranked.
I have tested the Ohms between the Injector harness end and FICM end. Pin #2,3,4 all showed 0.3 Ohms, #1 did not even register like 0.L on my Ohmmeter. Took FICM all the way off and it made a rattling sound inside, took it apart and about 4 pieces of what a buddy says where resisters. SO I guess my question would be , is FICM bad? Did something short it out, and/or is the number 1 injector wire bad. Plus the when I took the FICM off the back 2 bolts where loose, so I guess the FICM was bouncing up and down maybe. The front 2 where tight.

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 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 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 f350 with sct tuner (studded and deleted) with blue spring mod. And for the record I took the truck back to stock tune
Having an issue where after a long hard run, or a run up a hill, the truck starts running rough and acting like its not getting fuel. Sometimes it runs so bad it dies. Wait a few seconds, start her up and it runs fine. (until I do a hard pull again) I can hear a intermittent slight miss at idle as well at times. Tank is 3/4 full of fuel. No codes, no CEL. Also there is no smoke when this happens. just took her for a run and it happened, brought it back and shut it off, started it back up and idles fine.
Oil pressure seems good, can't remember exact numbers but it was in the 2000's I think even while it was dying. FICM voltage holds steady at 48 volts.
I changed the fuel pump and filter out to a different one. (a used one that was working when removed from a different truck) no change. I did not change the upper filter but it doesn't look bad.
I imagine a fuel pressure test would be in order but I do not have the equipment right now to do it. Am I right thinking its a fuel issue?

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.

This morning I noticed when I started the truck had a rough idle shaking truck. The truck felt weak. Boost would go up but truck felt like it was in sand. While coasting on the highway at 50-55mph the truck not only lags in power but vibrates viciously until the overdrive kicks in that vibrations in cab and ssteering wheel go away.. What might be going on?

I have 2007 6.0, rough idle starts, rough and no power till engine reaches running temperature, runs great after that. If the engine is off for half hour, and restarted, runs rough again till engine temp is back again.
