Ford 6.0L Power Stroke Diesel :: P0275 Code For Cylinder 5 Contribution

I have a 2004 F250 with a powerstroke 6.0. I have done the egt delete and oil cooler upgrade. Last weekend I did head gaskets, arp studs, new heads, injector o rings, updated stand pipes and dummy plugs, glow plugs, glow plug harnesses, water pump, and exhaust gaskets. After everything was done and truck was primed and started it ran really rough. I drove it a little to possibly purge any air and it still ran rough and I got a code p0275 for cylinder 5 contribution. I removed valve cover and oil rail and swapped injector 3 and 5. 5 was covered in fuel. After reinstalling oil rail I cranked engine over and saw cylinder 5 intake valves were not moving. Removed rail and rockers. Pulled push rod and it was bent. Installed new push rod a and reassembled. Crank engine over to verify all rockers were moving. Reinstalled valve cover and started truck. Truck ran great. Cleared codes and test drove. After test drive truck sounded like it was missing so I checked the codes again and p0275 was back! I know at this point I need to check the harness but any other possibilies you may know of? FICM voltage it good at 48v and oil pressure reads good as well.

Ford 6.0L Power Stroke Diesel :: 2003 F350 - Rough Idle / Cylinder 4 And 5 Contribution Balance Code

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?

Ford 6.0L Power Stroke Diesel :: 2003 - P0278 Cylinder 6 Contribution / Balance

I have an 03 ex with 03 motor. I use torque pro all the time and periodically check for any codes. Well, I got P0278 but no check engine light. It does seem to start a little different than our 05 with 04 motor. It sounds like it just doesn't fire right away or like it turns over and then decides to start. It doesn't make the destinctive sound at the end of cranking when it starts. I hope that makes since. I could tell it sounded different, that is why I checked for any codes. It also seems to run just fine down the road and at idle. Where to start or what to look for?

Ford 6.7L Power Stroke Diesel :: Thumping Noise From Exhaust - Code For #6 Low Contribution?

I have a code for #6 low contribution and a thumping noise out the exhaust. When I turn number 6 injector off the popping/ thumping goes away. Truck is straight piped and deleted. It started doing this after getting on it hard to get on the high way. Sounds like beating an empty pop bottle on something

Ford 7.3L Power Stroke (1999-2003) :: Loud Knocking Noise - Failed Cylinder 8 Contribution Test

My truck is currently stock and recently started making a knocking noise louder than it usually does. I researched and have found the injectors can make a knocking noise when not performing correctly. I took it to a local shop who hooked it up to a snap on scan tool and ran some tests. It passed the Buzz test but continually failed the contribution test on cylinder 8. I'm going to go home and remove valve cover and unclip the injector to see if the noise goes away. I'm sure hoping it does as an injector by the looks of things is definitely the cheaper option. I'm scared because if I was listening to a gas powered truck and heard the sound my trucks making I would assume it was a lower end noise. My truck only has 148,000 miles....

Ford 6.0L Power Stroke Diesel :: Glow Plug Cylinder 8 - Code P0678

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?

Ford 6.0L Power Stroke Diesel :: Shake At Idle - P0278 Code Cylinder 6

Truck all of the sudden out of no where started to shake at idle my first thought was that it is a miss. Then on hard acceleration blows black smoke with NO tune on at the time, plugged reader in and got code P0278 cylinder 6 contribution/balance. I'm assuming it is a dirty nozzle on the injector. Shake/miss clears out at about 900-1000 rpm. Truck as 247k on it. 50k on injectors. Has ported and o ringed heads, studded, and fully deleted, with bullet proof ficm. Would my assumption be correct?

Ford 6.0L Power Stroke Diesel :: 2003 - Cylinder 5 Misfire Code P2285

I'm normally in the 7.3 forum, but a friend has a 2003 6.0 with a P2285. I get the impression that on the 03 and early 04 models, this code is nearly always a failed ICP sensor or the wiring leading to it. It also has a cylinder 5 misfire code, but I suspect that's a separate issue. I had the truck hooked up and the ICP held pretty much steady at 870 psi. I didn't look at ICP voltage, but I'm willing to bet it was probably 0v and the pressure reading was inferred and not actual.

Will a failed ICP sensor also cause the truck to have decreased power? Any tips to make the sensor easier to change, like a certain socket/ratchet combination or anything? Is it easier from the top, or bottom? I do have a lift . . .

Ford 6.0L Power Stroke Diesel :: Code P0262 - Cylinder 1 Injector Circuit High

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?

Ford 6.0L Power Stroke Diesel :: Engine Missing - Code P2077 - Cylinder 6 Injector Circuit High

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?

Ford 6.0L Power Stroke Diesel :: Running Rough - CEL On With Code P2285

Wife just pulled in said your trucks running rough. Right out the gate went out Checked ICPV its at 0 KOEO... Noticed a CEL P2285...

ICPV seams to be Jumping all around at Idle...

it stutters and smooth's out some I believe its going into default mode...

its acting different then last time the ICP went south thinking a wire is shorted or that's my guess ...

is it just me or do Vehicles seem to break down more when its Cold...

Ford 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 7.3L Power Stroke (1999-2003) :: P0269 Cylinder 4 / P0284 Cylinder 8 Running A Little Rough

So I did a cylinder contribution test and a buzz test today. It buzzed evenly on all cylinders. Then when I did the cylinder contribution test I got these codes,

P0269 cylinder 4 contribution balance
P0284 cylinder 8 contribution balance

It has been running a little rough lately but not smoking. Seems to be chattering more than it was too. I did the FRx, HPx, CVDs and banjo bolt mods about 500 miles ago and it was a lot quieter and ran better. Just recently started running rough and a little louder. Could these injectors be bad? I did new injector O-rings about 800 miles ago. I ran the test with the engine cold and with it warmed up and got the codes both times. It seems to have a little bit of throttle flutter when holding it about half throttle while driving.

As far as I know the injectors haven't been replaced and they have 186K miles on them.

Ford 6.0L Power Stroke Diesel :: Intermittently Running Rough At Idle - Code P0269

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....

Ford 6.0L Power Stroke Diesel :: Rough Idle And Loping Upon Cold Start - P0488 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.

Ford 6.0L Power Stroke Diesel :: 2005 - Stuttering And Running Rough - Blackish Grey Smoke / Code PO269

2005 6.0 133000 miles... Truck has been stuttering and running rough for about 2 weeks, warms up and is somewhat better. Would stutter in the RPM range of 1600 to 2100 RPM, can push down on accelerator and power through it with no problems. Checked codes and got PO269 Contribution Cylinder 3. Changed all filters and oil change along with a bottle of hot shot secret in the oil. Truck is now blowing blackish grey smoke under throttle and when idling that smells like fuel. No coolant in oil, and no oil in coolant.is the injector shot, or injector sleeve bad?

Ford 6.0L Power Stroke Diesel :: Running Rough - Code P0404 - Black / Whitish Smoke Coming From Tail Pipe

Truck started running rough on way home the other day. First gave me P0404 code and would get black smoke along with whitish smoke coming from the tail pipe. I haven't been able to notice or track an amount of coolant loss yet.

Swapped EGR valve this morning and now noticed this once she kicked into high idle (still warming up). About to hook up the IDS, hoping I this is not head gasket .
