Ford 6.0L Power Stroke Diesel :: Rough Idle - Code P0270 - Bad Injector?
Nov 11, 2015
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.

2003, not deleted, everything was stock except for he put a Bully Dog on it with can tunes. Died on him was replaced ICP started up ran horrible was throwing different injector codes, IPR was at 84% at idle, plus had a lot of pressure on degas bottle.
Just finished studding, deleting, oil cooler, ICP, and injectors. She started up fairly easy, only to have the IPR still at 84%, ICP bouncing between 670s to 790s this just after start up from the work. Truck still runs horrible and still throwing #5 injector code also using AE and injector 5 wont Buzz. So, would be safe to say Injector harness and IPR sensor?

#2 contribution/glow plug/injector code ????? Harness looks good. What's the malfunction?? Runs rough. Never seen those 3 codes together.

So my truck is intermittently running rough at idle for the most part and sometimes slightly loses a little power while driving down the roads. Seems to run worse as it warms up. When it runs rough it sounds like a cylinder is missing. The truck is throwing code P0269 for Cylinder 3 Contribution/Balance. Smoking isn't horrible coming out of exhaust but it's there and it comes out at a constant rate. The injector has been replaced by the previous owner recently. It has an egr delete, new turbo, ficm, ficm harness, HPOP, and stand pipes.
When I put the starter solenoid wire to the battery you can hear the engine skip. I did a compression test on cylinder 3, put oil in the cylinder and did the test again to find that I still didn't have compression. Assuming that this was an issue in the head I had my doubts that it was a bent valve and it could have been a bent pushrod.
Sure enough I found the intake pushrod for cylinder 3 was bent slightly so I replaced the pushrod. I started the truck again and seemed fine at first but just like before it started to run worse as it warmed up.
I was able to drive it to the gas station real quick to fill it up on fuel and drove back home which is a short drive, but the truck was running worse and worse and it eventually died on me. I attempted to start and had to jump start from my other truck and the 6.0 would not start. I ended up frying the starter trying to start it so I'm taking a break from it for now.... Ended up pushing the truck home.
The only thing I can figure is that I don't have oil pressure in the oil rail which is why it died but I don't understand why the truck still ran rough and pulled up with the same P0269 code....

My '05 Excursion recently started having rough idle and some loping when started cold. It seems to run good and idles pretty good when it warms up. I'm also getting a P0488 code (EGR Throttle Control Circuit A Range/Performance). I do have a BPD EGR and I don't recall if that would throw a code alone? I'm taking a trip next week and want to get it straightened out. Does it sound like an EGR valve issue?
I also thought about a battery issue, I know that can cause weird problems. I have Duralast batteries and they always seem to fail at about 2-3 years. I took it in and they say it tested good but I'm not always sure with them. Long story, but when cranking for longer than normal, the cranking power would drop quite a bit. Checked battery and had some corrosion. Cleaned and upon further inspection, the positive post is a bit eroded at the base and sunken in. The voltage was about 12.35 after sitting all night, a couple of the cells were reading lower than the others (about 50%, other 75%) when checked specific gravity. I tested voltage after batteries had been in the truck overnight, then unhooked from truck when testing.
I also thought about a glow plug/harness issue. The truck cranks for awhile before starting, 5-6 seconds sometimes, but not all the time. It starts up pretty quickly when warm. That's been going on for some time. Anyway, I will try to get a video of the rough start after cools down.

I bought this truck a few months ago. After trying everything under the sun to try and rectify a poor running problem, it was realized that injectors needed replacing. Ended up putting in 160cc/30% unlimited diesel performance injectors. The truck has a rough idle and surging problem. After trying to install the chip from gearhead, the truck didn't run any different, ultimately (according to the shop doing the install) smoking the ECU. New stock ECU, same problem. Goes good under throttle, just idle is bad. I get weird looks at the gas station. People think it has a big cam.

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?

Been working on a 2005 6.0 with 218kish miles on it. When I got the truck it had a contribution 2 code stored, no check engine light, just could see the code on the code reader.
Truck idled like crap, lacked power, so I replaced the injector. Truck improved but still had a miss, this time it had a stored code of injector 6.
Ordered another injector, got it installed today. Fired the truck up, ran perfectly, drove it around, absolutely 0 issues ran like a dream. Parked it for a few minutes before starting it again to wash it. Rough idle, not horrible, not noticeable. Cylinder 6 contribution code stored again, no check engine light.
So I drove it, I drove the hell out of it for about 15 minutes with the AC at full blast, WOT, etc etc. By the time I was done, truck was back to running smoothly.
Just walked outside after dinner to see if it would still perform well, or if it would idle poorly again, sure enough, 6 contribution, rough idle.
I just changed fuel filters with OEM, air filter is new. I just cleaned the EGR valve- although maybe it's not clean enough?? Oil change is tomorrow (had to wait for the filter to get shipped in).
I'm at a little bit of a loss on how to cure this miss, unless it's possibly an oil pressure issue from bad/old oil causing it?

I just did a bunch of work on my 6.0. Here's a list- head gaskets, arp studs, new heads, 2 new injectors, updated stand pipes and dummy plugs, water pump, and all new injector o-rings. After messing around with a bent pushrod, cylinder 5 code and and replacing injectors the truck runs excellent. After driving it a bit I get a code "P2290 injector control pressure too low". The truck runs great with no low power, stalls, or hard start cold or hot. I do puff black smoke but that's because of the sct tuner on performance tune.

I have a 2006 F-350 4x4 CC LB. I recently had my check engine light come on coincidentally on my way to the auto parts store. Asked them to plug in the scanner and read the code. It had around 20! This truck has 40000 miles on it. All of the codes were dealing with injector voltage being low. All eight cylinders. So I'm thinking ficm is going out. I replaced the batteries shortly after this. I driven it a time or two after this and it started cutting in an out going down the road. Seemed down a few cylinders for a few seconds and pouring black smoke from the tailpipe of a stick truck. Made it home after it did this there times. Stated it up to move it a few days ago. Some white smoke that clears quickly and ran rough for a few, pulled it in gear surged forward and died. I cleaned the EGR valve and re o ringed it. Tested the drivers side pin on the FICM and have 47-48 volts with key on and cranking.

In the last 300 miles, I have replaced all 8 injectors with rebuilt units. Shortly after assembly I had P0264, P0270 and P0272, so I replaced #2 and #4 injector. When I went to pull the oil rail, the two screws holding the top of the #4 injector were gone and the injector was in half. Easy to say, this was this issue with that one. I am assuming #2 had a coil issue.
After assembly, I am still getting P0272 with a rough idle while cold or hot. It does seem to lessen at higher RPMs.
FICM has less than 300 miles on it. Atlas 40, Ultra mods from ficmrepair.com.
Injector harness is new.
Using AE - Injector buzz test is ok. Power balance shows number #4 with slight issues. I will post screen shots tonight. ICP is always within a few points of desired. It builds in excess of 3,600 at WOT.
I have only driven 10 miles since the assembly.
1) Can air in the system contribute to this code? Should I continue to drive around and reevaluate?
2) Should I send the FICM back to Ed for review?
3) Any other thoughts?

Have a 2004 F350 which had problems starting cold and once started had bad throttle response until warm. It also had a shudder at cruising speed when going up a slight incline, would shudder until turbo kicked in.
Pulled codes which related to FICM and codes for all 8 injectors. 7 injector codes were circuit low, cylinder 1 high. Tested FICM voltage and sent FICM out for repair.
Installed rebuilt FICM, cleared codes, and hard start went away, but cruising shudder is still present.
Only existing code is P0262 for cylinder 1 injector circuit high. I'm assuming that cylinder 1 injector is bad -- are there any tests to confirm before I take it apart to replace it?

I have for a week suspected my batteries were getting weak. just slower cranking is all. I took my truck in to have a viper security system installed and while he was doing his work he killed the batteries. I saw him hook up a battery charger and started the truck. He pulled it around to me and explained how the system worked and off i went. 5 miles down the road, on the thruway, I notice a miss and I'm down on power. FICM looked ok, 48V and it was charging, 13.8 I thought I would bring it to my shop and load test the batteries. On my way here, the check engine light comes on. At the shop, load tested them and they were weak. Installed 2 brand new batteries, started it up, no difference. Hooked up the scanner and pulled a code P2077 (cylinder 6 injector circuit high) Now what? I'm not sure where to go from here. I'm guessing either the FICM went bad or the #6 injector?

Engine light came on yesterday and started missing on take offs. Giving code p2285 Injector Control Pressure Sensor Circuit Low. I've done the research and understand the problem. It's the weekend and shops closed until Monday. Is it safe to drive in the mean time? Is there any risk of doing damage? What's the risk of it quitting or failing start in the short term, today?

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?

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 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.
