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 :: 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?

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.

I have an 04 f350 with an 03 6.0 motor. Truck started running very rough a two weeks ago. Checked codes and found p0274 and p0275. Both codes are for cylinder 5. I replaced #5 injector and truck ran like normal for a few days then began to miss again when operating temperature hits about 187+. It will show code p0275 once hot as it misses. When cold runs fine, starts fine. No smoke. Could I have put In a bad injector? It was purchased from AutoZone...

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....

I have a 2011 F-250 with 112k miles.
On 11/25/2016 at approximately 110k miles: my truck was 100% stock. I was about a half hour into a 3 hour drive and I got a Check Engine Light. I stopped to get some food and my truck was idling for about 10 minutes when the light came on. My code reader said it was for P0278 "Cylinder 6 Contribution/Balance". I cleared the code, restarted the truck and drove away.. I drove about another 5 minutes until I started hearing a real bad air leak and the truck just didn't feel like it was driving right. Check engine light never came back on, but it just didn't feel right so I towed it home.
The truck went to the dealer, they said they found the EGR Inlet Tube was cracked, and that explained the air leak sound I heard when I continued driving, and they said the truck was probably running rich from the lack of air and that set the P0278 code. They replaced the tube and everything was fine.
On 12/14/2016 with around 111,500 miles: upset that just one pipe breaking could take down the whole truck with no one having that part in stock to get me back on the road, I "deleted" my truck. Removed the DPF, installed "block-off" plates for the EGR (which goes in place of the EGR inlet tube), a Cold-Air Intake, and H&S MiniMaxx. (Exact parts can be found in my signature).
On 12/25/2016 with around 112,500 miles: I was getting ready for work and I started my truck using the Ford Factory Remote Start that was original equipment on the truck. The truck ran for about 10 minutes when I hopped in it and took off. As soon as I got in it, The Check Engine Light was on and I had a code for P0278 "Cylinder 6 Contribution/Balance". I erased the code and restarted the truck.. drove to work (around 50 miles) with no problems. Truck ran fine, I never felt any problems, and no smoke or anything like that.
10 hours later I'm getting ready to leave work and let the truck run on remote start for 10 minutes. I hop in the truck and drive away.. there's no check engine light, but, my tuner says there's two DTC's.. P0278 "Cylinder 6 Contribution/Balance" and now P0281 "Cylinder 7 Contribution/Balance"... I cleared the codes, restarted the truck, and drove home with no problems.
12/26/2016 I started the truck on remote start again for 10 minutes. No check engine light, but the tuner says there's one DTC for P0281 "Cylinder 7 Contribution/Balance". Cleared the code, restarted the truck, and drove to work with no problems. Got back in the truck after 12 hours, drove home and didn't get a DTC or Check Engine Light on the drive home.
12/27/2016: No DTC's or Check Engine light. Where I should start looking to fix this?
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

View 2 RepliesFord 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 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 6.7L Power Stroke Diesel :: 2011 - Sudden Power Loss - Cylinder 5 Dropped
My 2011 6.7 suddenly lost power, started making noise and then stalled out.
After finding out that there are zero 24 hour service companies available in the LA area, I was able to get it towed to the local Ford dealer.the next day they told me it had dropped the #5 cylinder and that they would have to tear into it to find out what happened.
While I realize that any thoughts on the situation would be primarily idle speculation, what would cause this to happen at only 125,000 miles.
Ford 6.0L Power Stroke Diesel :: Loss Of Power / Codes For Low Voltage / FICM And Cylinder 6 Misfire
Well, coming home from work Friday and my truck turned on the check engine light. I did not notice any loss of power or other driveability issues. When I got home I pulled the DTC's. I got P0264, P0273, P0276, P0279, P0611, and U0306. The first four being low voltages. The Second FICM. And the last cylinder 6 misfire.
I sent a message to Ed at FICM Repair asking if there was anything to check before I pulled the beast. He said no it needed service no matter what at this point. BUT, I needed to test batteries and alternator. So I spent some time today pulling off my FICM.
I went ahead and pulled the EBP sensor and tube off from the exhaust manifold. The manifold end was very clean. BUT, the sensor end had a noticeable restriction. I would guess a 40% restriction. I cleaned the tube and the sensor and put it back on.
Next I moved to the EGR. I pulled it off and it was dirty but not what I would call restricted. The valve moved freely. I cleaned it anyway and blew out the manifold before I reinstalled it.
I have the batteries on a charger right now. Once they each charge for 12 hours each I will let them sit a day or two before I load test them. They are about four years old, AC Delco 60 month 875CCA batteries. I have had problems the last 6-8 months with staring the truck. If she sits for more than 3-4 weeks without being run she turns over slow and won't start. So I have had to jump start her a few times. And before you ask I have done a parasitic check and only have .05amp draw. So maybe the alternator is getting weak.
On that note I pulled the alternator and will get it bench tested this week. While I was there I noticed the top grooved and smooth idler pullies were a little "wobbly" so I yanked them too and will replace. Might as well do the belt while I'm at it. Boy this is going to get expensive real fast.
So, I decided to go ahead and replace the bottom coolant recovery hose and the long hose/pipe heater hose too. Boy it never ends. Oh well. I would rather do it now while I have stuff pulled off and it is easier to get to. Ordered those parts from RockAuto to the tune of 219 dollars. OUCH!!!
I accidentally broke my new engine oil dipstick while I was trying to get to the FICM!!!! CRAP!!!! More money. So......... Is there anything else I might want to look at while I am there?
The truck is 2006 F250 6.0 PSD CC SB 4x4 mid optioned XLT with 108,000+ miles. I have a 4" turbo back exhaust, AFE Cold Air Intake, Blue Spring, Hypertec Power Program 3 on the lowest setting, and an after market intake elbow at the intake manifold and an engine oil bypass filter. Turbo was pulled and de-coked about 18,000 miles back. Otherwise no issues. The 90,000 mile service was done about 10,000 miles ago. She gets regular services.
How about methanol injection? Will that keep the intake clean from the EGR sludge? I'm not thinking about added power, just keeping things cleaner? I plan to do the Atlas 40 when the FICM gets repaired.

View 13 RepliesFord 6.0L Power Stroke Diesel :: 2006 - Cylinder 2 Misfire?
I have a 06 f250 with 135k that I keep getting a #2 contribution code. Power balance shows cylinder 2 low as well. No circuit codes and everything sounds good on a buzz test. Valvetrain is actuating as expected. I changed all 8 injectors w/ motorcraft with no luck. I get over 300 psi on a compression test ( 175 psi on 1st stroke then maxed my gauge on the 2nd). It smokes until I disable cylinder 2 then it pretty much clears up. I did notice I could move the top of the valve stems about 1/16", this seems really sloppy. Very little blow by and the oil cap stays on up side down until it rattles off. Any other 8 deal other than pulling the heads? I just bought this truck and have little history on it.

Ford 6.7L Power Stroke Diesel :: Glow Plug Fell Inside The Cylinder
I would like to know if i am the only one that had that problem... a few weeks ago, I had to stop and get the truck towed to the dealership and they told me that my engine was shot. Then they told me it was a glow plug that fell inside the cylinder... didn't know it was possible but any way it was under warranty.
Last Monday they asked me to bring all my service receipt and that ford is asking them to take the engine apart and study it before they would ship a new engine... Are the trying to get away from paying it under warranty? The truck is 2011 with 80000 km (50000 miles).
Ford 6.7L Power Stroke Diesel :: Minor Oil Leak On Bottom Of Cylinder Under Oil Fill?
I was draining my separator and noticed some oil accumulating on the bottom of the cylinder head right under the oil fill on the drivers side. My truck is 12 days out of engine warranty.
It's last service was probably around a year ago when the engine was torn down to replace the exhaust valves per the TSB.
