Ford 6.0L Power Stroke Diesel :: 2006 - Cylinder 2 Misfire?
Apr 4, 2017
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.

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.

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 . . .

I bought an 06 6.0 f 350 4x4 dump bed cheap. seller said it was sitting for 1-2 years and wouldn't start. ficm is at 48 volts fuel pressure is at 100 oil pressure builds fine, then checked compression and reading no compression in any cylinder. My mechanic says new motor or possibly both head gaskets are blown.

Started having some crank no starts intermittently. Scanned and found codes for cam sensor. so I was in a pinch and a hurry on a sunday so I picked up a BWD brand cam sensor from parts store and installed. I have not seen this issue since but started noticing other thing going on. I noticed a few weeks ago my truck was starting a little strange. as it would spin over before firing off, it didn't sound right. I couldn't pinpoint if it was due to slightly low compression on one cylinder or one cylinder had a little fuel or oil in it and that one cylinder was actually firing while cranking over.
I also was noticing a little longer crank times than normal. didn't matter if engine was cold or hot. sometimes would fire up quick and sometimes it took a few seconds. most of the time I couldn't catch it on my scanegauge if the ICP was low due to the lag on the scangauge.
Well one day on my way home from work (50 miles one way) I stopped about half way to fuel up. after filling up and attempted to restart the truck it really acted like it didn't want to start but did after cranking for about at least 10 seconds and started rough. and of corse my scangauge decied to hate me this day because it would show any data until I unplugged it and plugged it back in. so started home. felt like it had a very very light miss on the way home. when I slowed down to turn onto my road the truck died. took forever to get it to start back up. this time the scangauge was reading and I could see ICP was between 300-400 and IPR was 85%. so low pressure and not reaching the 600 needed to fire. once it started I limped it home. scaned it with my Auto Enginuity and it didn't show any codes.
So that much I can see I have a leak on the HPO system. but I done a lot of work to the truck about 2-3 years ago. roughly 80k-100k miles since the work. what I done included...
OEM oil cooler
OEM (updated)dummy plugs, standpipes & STC fitting
OEM head gaskets and ARP studs
BPD EGR cooler (I should have deleted)
ALL other engine gaskets(Bed plate, oilpan, front&rear cover, ect.)
OEM glow plugs and harness
OEM blue spring upgrade
Cleaned turbo veins
2 OEM REMAN injectors. (cant remember which two) had contribution codes one on each side.
This is all I can remember right now. Now have yall seen the updated dummy plugs and standpipes leak? I have not pulled valve covers to air test the HPO system yet.(don't have my air compressor at my new house yet). Here is what I have done so far:
Fully charged batteries.
I did do a bubble test. pulled upper fuel filter cover off and removed filter topped the bowl off and turned engine over using the wire by the passenger side battery. some bubbles but not a bubble bath.
Checked fuel pressure (not running) its 60psi. did not start truck because I need a different fitting so I can run the truck and check pressure while running.
while doing the bubble test I could hear that one cylinder is low on compression. but I do not have any misfire or contribution codes.
when I ran contribution test on AE its not showing any particular cylinder lower than the rest. but the line is not very solid at all.
Here is what I plan to do.
Compression test on each cylinder.
Looking at the Harbor freight kit. Looks like it has fittings for glow plug and injector holes.
If I can do compression test on both glow plug and injector holes this should show weather my injector orings are the cause of the low compression.
Then I have to airtest the HPO system and find the leak.
Am I on the right track? what else should I check? Guess I should add that the truck currently has 297K miles.

I've got an issue with my truck, I was towing home my camper this weekend and my engine started missing out and vibrating very bad, then it overheated... pulled over and check codes, p0263, p0299, p0300, p0301. Oil all over engine, tons of blow by, definitely a dead miss on cylinder 1. Smokes bad out of exhaust, zero power, and blows cap off of oil filler when loose, tons of smoke and oil from ccv.
My question is, could it be in the valve train? Or is it going to lie in the piston/rings? Blown head gasket? It did overheat, but didn't puke out of bottle, turbo timer kept it running for a bit after I shut it down roadside, egts were definitely high. Also the egr is deleted, have a predator programmer with custom tune for she delete.

So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong. Any way to check what's wrong myself?
Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...

New to diesel trucks and wondered if this recurring code is a serious problem. I clear DTC and truck will run fine. Might stay off for 2 days or 2 months and same code comes back. Truck seems to run just fine even with service light on.

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.

2007 F350... I noticed I have a small power steering leak where the master cylinder bolts onto the hydroboost. Is there a o-ring or seal between the two? or do I have to replace the hydroboost? Been looking online for a schematic but can't seem to find one.

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 a 2003 f 350 6.0, when under a heavy laod such as towing a 3000-pound trailer up a long hill at approx 60mph and 2000 rpm it intermittently mis fires.The boost gauge bounces up and down and i here a poping sound from the engine compartment.I have had it to several dealer and independent shops but with out the trailer or a heavy load it runs perfectly.They have told me fuel pressure is good and changed all fuel filters with OEM parts.

I have an 04 F-250 6.0l Power stroke diesel with a problem. The engine starts fine and runs normally until it gets warmed up. Once it is at the normal operating temperature it starts to sound like it is misfiring when idle. Once I accelerate it sounds normal again but when I slow to idle the misfire comes back.

Im replacing hydroboost and master cylinder and I cannot for the life of me get the master cylinder pushrod (which must be reused) out of the hydroboost unit. There is a spring, retainer and pushrod that I cannot get to release. I know it has to be very simple, I just cannot see how it releases.

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?

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).

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 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.

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...

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?

I've got an '04 6.0 that's recently developed an engine performance issue and I was hoping to get some leads on what to chase down this weekend. The truck has 75,000 miles on it and has been trouble-free since new when it comes to the motor. Recently I've noticed that, usually at a stop light, the idle will occasionally get very rough and the normal diesel "clatter" noise becomes rather rough sounding- almost like every other "clatter" disappears if that makes any sense. Up until last night this was happening very infrequently and usually only for a couple of seconds. I wasn't really sure what the issue was then and would rev the truck in neutral and the issue would go away. This has happened a handful of times in the last month or so.
I drive a company car all week and the truck only gets used in the evenings and on the weekends, and last night my wife and I drove it to dinner. The truck cranked and started normally and was operating smoothly until we got out of our neighborhood (about a mile of driving), then the rough running condition described above surfaced and continued throughout the 7 or 8 mile drive. This was the first time that it ran like this for more than a few seconds. The truck was running bad enough that you could feel the misfire or 'chugging' at speed. When the truck would shift into overdrive and the torque converter went into full lock-up, you could really feel this as the engine was lugging. I tried to keep the truck out of overdrive because it was shaking the truck pretty badly. When we came out of the restaurant I thought maybe the issue would be gone but it did it all the way home as well. Throughout both drives the Check Engine Light did not come on.
When I got home I got my DiabloSport Predator because I remembered it has a code scanner in it. I have never checked for codes before so I do not know if these are fresh codes, but there is a P0282 Cyl 8 Injector Circuit Low and a P1000 OBD Systems Readiness Test Not Complete in there.
While I was in the driveway with the engine idling badly for a few minutes, the issue completely went away and the truck smoothed out for a few minutes. It was like someone flipped a switch and the truck instantly ran properly. After a couple of minutes however, the issue instantly returned. I tried to clear the codes with the Predator but they will not go away. I am not sure how solid of a scan tool the Predator is????
I did a lot of searching on here last night because this is bugging me, and the symptoms I saw on here about the ICP sensor make total sense based on what I am experiencing. People were describing to a 'T' what I am experiencing. However, I do not have an ICP sensor code and when I searched for the P0282 that I do have I read about FICM issues here.
The rundown on the truck- '04 F-250 CC 4x4, truck was bought 10-03 and I THINK I remember the build date as 9/03 (maybe 8/03). Automatic transmission, DiabloSport Predator with 60hp tune, MBRP turbo-back exhaust, everything else stock. Oil was changed about 4,000 miles ago, both fuel filters done about 2,500 miles ago.
A few questions:
Could the ICP be my issue even though there is no code for it? Could the P0282 be coming from an ICP issue?
I've read about early '04 trucks having '03 motors and something about an updated harness for the ICP- could I get more info?
Is my truck part of the affected group with the wire-chafing I read a little about? If so, could that be causing this and what should I look for?
Does the P0282 immediately point to a FICM issue?
