So I changed my oil with T6 and archoil and immediate miss at around 1500rpm then it clears up. I can stomp on it after that and it's fine. I know this has happened to others. My last oil change was also T6 and archoil. 2005 F250, stock, atlas 40, 216,000 miles.
View 5 RepliesMy truck is developing a hesitation or a miss when accelerating. It only does it in the beginning of accelerating like when just starting off from a stop. Seems like its more noticeable with the more I get on it. If that makes any sense. When just lightly accelerating it doesn't do it, like going slow through town from light to light. But when I give it more is when I feel it. It seems like it only does it before the turbo kicks in and it puts out a little smoke too only before turbo kick in. After that it runs good with no noticeable miss or anything. WOT runs feel good after it clears up. Its just when first starting out with anymore that 1/4 throttle I can feel it.
View 14 RepliesI have a 2004 Ford F250 with 174,000 miles the truck has a slight miss a rough idle one hot or pulling I have 2 codes nut no light when I go into the ford oem feature in my scanner a PO 272 and a PO404 .. Where to start?
View 4 RepliesI've had good running on the truck but lately in the cold the idle has a weird skip to it like it's missing on a cyl. It will start fine, and run fine for about 30 seconds. Then it will start to mis. When giving pedal it goes away and it's driveable but it doesn't sound right. After a bit of running it's fine for the duration while warm. My monitors are I think all good, 48.5v, icp about 1250 psi. Is this the famed "injector stiction"?
View 5 RepliesChanged the fuel filters. No issues in replacing.
Primed them by the book - key on 30 seconds 6 times
Now I have low pressure warning and reduced power.
All parts were FOMOCO...
2005 6.0l - codes are P0261 Cylinder 1 injector circuit low. PO263 Cylinder 1 Contribution/balance and PO270 cylinder 4 circuit low. Ficm still reads 48 plus or minus .5. What is really puzzling is how changing the oil cooler and the EGR cooler would create these problems. Did I screw up the injector harness. Vehicle does not smoke either white or black. Low idle miss and at 55 it chugs once up to speed. Don't want to go Ford if I can avoid them. Whats going on.
View 7 RepliesTruck has not been bullet proofed and has aftermarket air intake. Truck has 185km on it (purchased at 160km a year ago). For the Ham Radio guys out there, this is the most electrically noisy vehicle I've owned with S9+ noise while accelerating and S7 going down the highway ...
The faults show up as:edit Can be hard to start cold, takes couple of tries if it's been sitting for a bit (week or more)
No power when cold, that is a lot of pedal results in little power
Misses a lot when cold
Light blue smoke when missing when cold
When fully warmed up which takes 15 minutes of idling regardless the time of year:under load (heavy acceleration while loaded or not, or just in towing, or carrying) it misses a few times a minute, otherwise runs well
It feels like it just doesn't fire a cylinder if it were a gasser, or as if the spark plug weren't connected, but it's not a constant miss, it is intermittent. No load means hardly any misses. Load means lots of misses even running down the road. Should be pulling hard up a hill where it misses lots more.
What I've looked at :
FICM voltage 47.8 standing, 47.6 cranking and running.
FICM is aftermarket and there are no cold solder joints.
Added Archoil 9100 with no change
Wires to FICM are tight and connectors aren't cracked
edit Wires to Injectors are tight and connectors aren't cracked
Exhaust temps range between 500F and 800F during any of these events
Basic ODB reader shows no codes
I'm looking for a couple of things - I'm not much of a mechanic so this has to go to a shop for diagnosis and repairs. Before I run it someplace, what sort of diagnostic tools should that shop be equipped with to find out what's going on? Also, given what you know of the problem, am I likely to damage things if I continue towing activities?
Getting ready to take my Truck in for the Radio turning offt. About half the time I start my truck the radio doesn't play sound, it's on but no sound. If I touch it or change the station then sound starts to come out, is this normal?

Just changed my alternator, that was the easy part apparently...............
Cant get fan belt back on? My pulleys don't look the same as the picture under the hood. I can see a idler on passengers side down low, but cant seem to make it move to give me some slack.
What kind of tool to use on idler to get slack?
Ok, so I have read on this subject and there are lots of posts about this being normal but why? What causes this? I have recently owned two 6.0's and neither of them had black oil even when I changed the oil! My last 6.0 a 2006 had oil that was nearly the same color out of the drain plug as the oil I was putting in! Why this happens on the 6.7.
View 10 RepliesI 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.
View 6 RepliesI've seen the gods of the diesel engine do some amazing things on these forums, so after a year of pulling my hair out, I've signed up to try this myself.
This time least year,I bought a 2004.5 6.0L F-250 with 196k on it to haul around the state for my new business. At this time, I knew nothing about diesel engines AT ALL WHATSOEVER, but I've never been afraid to tackle anything and mechanics are not totally foreign to me. Not to mention, I was hoping everything might just go peach-ily for at least a couple years. (for what it's worth, My dad and his family are mostly shade tree mechanics and I'm a power plant operator so mechanical concepts are not totally foreign to me, just never had a diesel before)
To begin, I purchased the truck and everything was fine for about 2 weeks. Then abruptly one morning I noticed a couple of hefty surges on the way to work. Then, on the way home I thought all was well until about half way home, it did it again! as I was pulling up, it galloped once I pulled my foot off the pedal. like ba-DA-DA-DA-da-da-da-da-da-da-DA-DA-DA-DA-DA-da-da-__ and then STALL! Shaking with concern over potentially an awful purchase, I turned the truck back on only to find... that it's fine?!?? No problems for the next two days and then it happened again. then good for a week, then again. then good for 2 weeks, then again. so then I bought auto enginuity and an edge insight to do some troubleshooting. Let that sink in as I explain it's history a bit.
-All but one injector is ford remanufactured the other is stock (was never told which one)
-replaced head gasket with another OEM
-ARP Head Studs
-EGR delete
-HPOP AND STC fitting both replaced
-FICM replaced
-Oil cooler replaced 50k ago
-ICP and pig tail replaced right before my purchase
- Has been through roughly a handful of ICP's since I've had it (I'll explain)
-I've cleaned the EBP tube a lot and updated it to the newer ford sensor with the flare fitting
-I use Rotella T6 5W40 and CAT ELC-1 Coolant.
-Deltas are under 10 at normal driving
-I typically drive under 2200 rpm until warm then like a banshee at operating temps.
Now one year later, its not fixed, but I feel like I'm close.
The DTC's I have seen are ICP sensor circuit intermittent (I think po2884) and Power Blance contribution failure from cylinders #2 #7 and #8 but never at the same time.
Every time I replace the ICP, it will be problem free for about 6 weeks and then it will return full force (surging and galloping when warm about 50% of the time)
During a possession I see the following:
*Cylinder power contribution test yields no issues at idle or when cold. when "possessed", the whole baseline across all cylinders goes up and all cylinders dip and return at random. none singled out
*ICP voltage fluctuating from ~.6v to 1v (.24 @koeo) *Also during a surge*
*ICP PSI dancing up and down ~600 to 900psi (0.0 @koeo and ~500 at normal warm idle) *Also during a surge*
*IPR% bumps up and down ~25% to 30% (15%@ koeo and 23% at normal warm idle) *Also during a surge*
*FICM Voltage anywhere between 47.5v and 49v
*EBP is normally 15-20 psi
*Boost is 1-7 normal and is not affected by "possession"
These numbers have taken a long time to get since it will only be possessed for about 3-10 seconds at a time and then will disappear for days. The stall has only happened about 5 total times in a year. The surging is much more frequent. I usually get a buck or 2 on any given trip that is longer than a half hour but NOT IMMEDIATELY AFTER AN ICP REPLACEMENT.
On one occasion, I noticed that the ICP PSI actually tanked to about 350 right before the IPR went from 25% to 40% right before a posession. I was driving about 35mph through town at the time.
Here's my thoughts...
- Did that one occasion clue me in to an intermittent HPO system leak causing the truck to briefly over-compensate by spiking the IPR?
- Is my ICP pig tail jobby done incorrectly? If there was a short, wouldn't I see the volts drop to 0? I have another one and will replace to rule it out.
- I have yet to test my fuel pressure, but I figured if it was low, I would have lost injectors by now. (I replace filters probably too often but next empty tank, I'm dropping it and checking the screen and strainers)
I should also mention that I have buzz tested the injectors and I can hear each one clear as day, and that for REALLY long trips, it actually returns to normal. In other words, my window of death is between 30min and 2hrs of driving; invincible after.
I changed both fuel filters on my 2015 F350 6.7 I turn the key online for 30 seconds then turned it off for total of 6 times when to start the truck this morning after driving it yesterday and it took a little bit longer to turn over before it finally did, did I miss something up that I do something wrong. So I let my truck warm up this morning after going to start it at took a little bit longer for it to turn over I turned it off wait a few seconds then turned it back on and she started up how she used to perfectly fine does it just need to go through a drive cycle. This is the second fuel filter replacement nothing was wrong with the other ones I'm at 40000 miles now ... also it seems like the fuel filter on the frame rail is louder if you put the filter in upside down on that will it fit stupid question I'm sure I did it right but thought I'd ask before I tear it apart....
View 14 RepliesSwapped a new oil cooler and welded Egr shut. Truck ran fine the first 3-4 times I started it except for exhaust leak at the y-pipe/turbo connection. Tried to start it today and it started then ran real rough, blowing whit smoke. Now it will not start at all and blows whit smoke. The only codes I'm getting are egr codes that I've always had due to having the 05 and up intake elbow and the egr turned off via sct. What could be the issue?
View 8 Replies2011 F250 6.7 Had the fuel filters changed by the dealer today. No noticeable sounds when I left the dealership, & no fuel stops on the way home (120 miles one way). When I got home, before shutting off the truck, I heard a loud groaning/singing from inside the truck. With the truck still running, I get out, & the groaning/singing is very pronounced....never heard this before & appears to be emanating from the fuel filter underneath the truck.
I turned the truck off, then turned the key back to the position that the fuel pump turns on, and wow, the pump is very loud. Definitely something going on because when I turn the key for the pump to turn on but not start the truck, I can feel the vibrations of the pump working from inside the truck and when listening from underneath the truck, it is very loud. Before today, the truck never made this noise and never heard the pump before.
2003 6.0 psd owned two years driven 2 months due to money thrown prior to forums and scangauge 2. Bought truck in chicago drove home. Oil in coolant. Did egr delete oil cooler all gaskets orings etc. New oil filters motorcraft fuel filters .new rad fluod wix trtmnt. Truck started right up. Still had same intermitantstudder as always when cold. Always exp those sysyems until hot then here and there until parked then hot no start or hard long start when hot. Knew something was wrong and waited for it to come to a head well it did in may.
I was driving coming up to a stop sign and truck died like i shut key off. Refired once off ether. Lasted 3 seconds died no restart period didnt even want to just crank crank crank.
ok towed truck i thought it was injector orings. Changed them still nothing . New icp. New cpm. Now have icp of 66 to 120psi cranking.ipr 14.40 koeo up to 84 when cranking. Ive unplugged just get eratic reading ipr stays same. Checked ficm 47to47.5 cranking and koeo. No codes beside for my egr delete and when i unplugged icp. I've been tinkering on this truck for a couple years now still lost bit getting better. I now have driver valve cover off . Its a 2003 .
I've only owned a 6.0 for about 10 months now. I have a 2005 SCab FX4 with 125,000 miles on it. It has an Airaid cold air intake and MBRP exhaust without a muffler, everything else is stock. The stuttering/hesitation starts at about 1500 rpm, is worst at 1600rpm and seem so to go away at 2000rpm. It also seems to hesitate when I barely press the gas pedal while driving. Based on other fuel issues with other vehicles, I would assume this is a fuel problem, but am not well versed in the 6.0 engines. Fuel filters were said to be good by the dealership about 10,000 miles ago. EGR valve was replaced last week. I'm not blowing smoke of any color, even at WOT. I was thinking an injector may be the issue, but I show no other symptoms besides the hesitation/vibration. I don't feel any lack of power when I give it full throttle. I would like to know a definitive way to diagnose the problem without going to the stealership.
View 7 RepliesI'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.
View 6 RepliesMe and the wife just now noticed this issue after about a week of owning this 6.0 f350 auto 4x4. Leaf spring front and rear. Long bed. Listing all this stuff because not sure if it matters.
Around 50mph if we drive normally about 1500rpm the truck seems to jerk a little as we climb in speed. If we get the truck into the 2000rpm range it goes away.
Not sure if it's suspension, transmission or engine. Any clue what it could be. ???
Very weird thing happened on the way home from work. When I left work (not to full temp) at about 1500 rpm and 30 mph (had to be at 30mph--seemed to be the key) the whole truck felt like it was rolling across rumple strips (the ones one the shoulder of the road) all vitals were normal and it was gone once on the interstate and up to temp (I did gon on it to blow out anything that may have needed to be) it felt more like drive line but honestly can't say. 2006 F350 4X4 ....
