Ford 6.0L Power Stroke Diesel :: 2004 - After Start Up Rough Idle And Power Lag?
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.
Ford 6.0L Power Stroke Diesel :: 2004 F250 - Slight Miss / Rough Idle / Loss Of Power

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.
Ford 6.0L Power Stroke Diesel :: 2004 - Rough Idle - Blue / White Smoke?
2004 f250 6.0, 173k miles. I just had the head studs done and a new head due to a crack in one head, I got it back 3 days ago and she was running great. I towed my landscape trailer yesterday full of mulch and only went about 5 miles with the load, after the job driving to another one I noticed it sounded like it was missing at idle with a small amount of white smoke. Drove it home let it sit overnight, started it up this morning and a cloud of white/ blue smoke and a horrible rough idle. Smoke does not stop.

Truck (04 excursion, 2WD, early build 6.0, 160k) started missing and rough idle on way home from work after sitting all day in rain - parked. started fine in morning and drove to work with no trouble - it was raining over night too.
To get you up to speed. for a few weeks before had intermittent trouble starting. would fire up as normal, fast and loud, but then stall immediately (usually after sitting overnight). would start back up but with a little long on the key and some gas pedal action. only happen one out of ten or twenty starts and seemed to follow getting fuel in unknown locations while on a trip out of town. decided to change out fuel filters and drain separator. seemed to fix it for a week or so then it happened again two days before above event, while weather was dry. Not sure if related but only recent problem to speak of.
Back to current:
- no check engine light or codes (I have a scanner)
- stalled out close enough to home the night in question I rolled it into driveway and tried to start it while rolling in neutral - no start
- once parked in driveway also no start
- next evening wanted to get it into garage (to dry off) and it started but rough idle and missing. this was after 24 more hours sitting in rain.
- been in garage 24 more hours and this evening got it to run but same result (rough idle and hard start). tried to check connections (mainly FICM) and move wire loom around - still same.......
Where to check next, need some diagnostic...
Ford 6.0L Power Stroke Diesel :: IPR Value And Intermittent Rough Idle
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?

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...
Ford 6.0L Power Stroke Diesel :: 2005 - Rough Idle - No Power - Black Smoke?
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.

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?

View 3 RepliesFord 6.0L Power Stroke Diesel :: Rough Idle - FICM Is At The Start Of Going Out?
So after replacing all injectors, I was getting a rough idle and drive. Got an imbalance on 5 & 4. Cleared out codes and 5 still showed. The guy doing my work and I couldn't trace it to anything so we thought well maybe we got a bad one. Did fail the buzz test. So got a warranty one and put in. Wouldn't you know it's still not running quite right. Only thing we can think of is maybe the ficm is at the start of going out. Voltage reads good still though. Staying constant at 47/48. Is more noticeable to run rough when starting from cold then smooths out but you can still make out/feel an injector going in and out.
View 14 RepliesFord 6.0L Power Stroke Diesel :: Intermittent Rough Running At Idle
In your experience, what issues have you seen that caused intermittent rough running at idle, but did not throw a code. I have monitored (with numerous scanners/gauges) this 6.0, but cannot get a code or see any of the sensors out of spec.
At Hot idle:
IPR: 24.2
ICP: 640
ICV: 0.90
MAP: 14.7
MAF Volts: 1.5
EOT/ECT Deltas within 10 and Avg ECT=192, EOT=199
EGR Valve cleaned and EGR demanded = EGR Measured
Vehicle will run rough after long runs or towing. Cylinder Balance test showed all injectors on. What could be the cause?
Ford 6.0L Power Stroke Diesel :: Rough Idle And No Fuel Pressure
I head out to work this morning and truck drive fine. I do not get on it. I cruised on the highway for 12 miles at 70 mph. I get to a traffic light and then it begins to idle rough and my fuel pressure gauge reads 0. I replace both filters over a month ago and did the blue spring upgrade at the same time. I've put over 2000 miles on the truck since then without issues until this morning. Also the fuel pump was replaced by the dealer a year ago in July. No check engine codes. Where do I start looking?

Trying to get some assistance on a mystery oil leak. I see wetness above the oil pan on the left side near a tube. That is the most fresh oil I can find at the highest point. The passenger side and starter also have drips, but i am thinking it may be running across the oil pan rail as I cannot any source on that side. Also, recently started having a rough idle - surging. Of course I thought ICP, doesnt feel wet.
View 6 RepliesFord 6.0L Power Stroke Diesel :: Rough Idle - Code P0270 - Bad Injector?
my excursion just started hard and had rough idle one morning then code P0270 - injector, FICM or wires between are the logical choices I think.
started with wires - all connections good at FICM and injectors (applied dielectric silicone) - checked all 4 wires from injector connector pins for resistance with omh meter from X-1 connector. no change
so next is FICM. couple years back sent to ed for repair. if I remember right it was power supply side only so the "brain" side might have gone? good news is could I get a loaner FICM off fellow 6.0 and installed (can't confirm condition of loaner - trucks been parked a while) same code same cylinder - no change.
I read somewhere possibly swapping two injectors (say 2 and 4?) and see if the code follows the injector or stays with the cylinder, further test for a bad FICM
Is that necessary? I would hate buy and replace the #4 injector just to put it back together to find no change then forking over 6 7 hundred more on a new FICM.
Ford 6.0L Power Stroke Diesel :: Rough Idle - Shaking At 1500 - 2000 Rpm?
I'm having a problem with my 6.0 back in September I started to notice a little miss with some black and white smock while accelerating so I took the truck to a power stroke specialist near my house to have it diagnosed they said my number 5 injector was starting to go bad so just this last week I finally got up enough money to get the injector changed I got the truck back yesterday from the mechanic. While driving I get a lot of shaking right around 1500 to 2000 rpms when I let off the accelerator it smooths out if I mash on it and keep the RPMs above 2000 it smooths out the truck still has a lot of power no check engine light has ever been on through this whole ordeal and there's a rough idle I guess the best way to describe the shacking would be if the truck was a standard shift and you were pulling a hill in to hi of a gear.
