Ford 6.0L Power Stroke Diesel :: 2006 F250 Running Rough At Idle
Jan 2, 2017
I have a 2006 f250 with a 6.0 with sct livewire, arp studs&gaskets, oil cooler, blue spring mod, sinister egr cooler and it had been giving me some real troubles lately. Started off as a code for injector #8 so I replaced that and while I was in there I rebuilt the oil rail with new nipple cups and orings, replaced standpipe and dummy plug in that bay(also updated the arc fitting less than a year ago), new exhaust back pressure sensor tube because it was right plugged with carbon, and a new egr valve because that was right packed with carbon as well, all backed together and torqued to spec from the Haynes manual and the truck still sounds like its missing at an idle with some light smoke(just smells like unburnt fuel). From there I went to test the ficm which is also only a couple years old and it seems to stay at a constant 48v so at this point...

Truck has been doing this and now getting worse. 06 f250 6.0 147,000 miles. Runs like crap when you first start and truck has trouble shifting when I first take off in the mornings until it warms up then it idles fine and runs like a champ no problem shifting. Not in a cold climate 40F at the least. Not trying to take it to the dealer and get raped. Been doing research some people say get the inductive heat flash, some say needs new injectors, some say could have a bad gasket on the injector idk. I'm trying trying to get it resolved....

In your experience, what issues have you seen that caused intermittent rough running at idle, but did not throw a code. I have monitored (with numerous scanners/gauges) this 6.0, but cannot get a code or see any of the sensors out of spec.
At Hot idle:
IPR: 24.2
ICP: 640
ICV: 0.90
MAP: 14.7
MAF Volts: 1.5
EOT/ECT Deltas within 10 and Avg ECT=192, EOT=199
EGR Valve cleaned and EGR demanded = EGR Measured
Vehicle will run rough after long runs or towing. Cylinder Balance test showed all injectors on. What could be the cause?

Ok, so I have a 2004 F250, with 6.0L. when driving at a steady speed (doesn't matter what speed), the engine will run rough when coming to an idle, and stay running rough until I shut it off and let it sit for a bit.
After I cycle the key a few times it will fire up and run fine, so I came to the conclusion that air is getting in the fuel system. I then took the filter cap off that is located in the engine bay and cycled the key, which produced a lot of bubbles, which I am assuming shouldn't happen.
I guess my question is, should I have air bubbles in the filter bowl, when cycling the ignition?

I have a 05 6.0l. Egr deleted. And my truck has a rough idle and power loss. Ive tested the ipr and the icp and they are reading at specs. I've also replaced the Hpop about 1500 miles ago. It has a real rough idle until it's at running temp. And it has power loss, I'll be driving down road and theres no where near has much power has there should be. And the idle will jump between 1500 rpm and 2000rpm.

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 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 have a 2007 F250 4X4 6.0 diesel. When first started it idles extremely rough to a point it sounds like a old gas engine missing. But after it warms up for about 15 minutes it runs and idles like a new truck. I'm thinking it's the injectors if so is this something I can change/clean .... It's 98* on a cool day , when "cold" I mean just started for many hours.

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.

2006 F350 6.0 ... I am piling up parts for a bulletproof party later this summer. It has gotten grumpy ahead of schedule. I will hook up the AE tomorrow for consultation.
In the meantime. Running rough at 50. Seems to accelerate from a stop semi ok. Sitting at idle, holding rpm at 1750 I hear kind of a thump under the hood and the rpm drops 300, then slowly finds it way back to 1750 and it repeats itself.
This thump has not been noticed in the past. Could this be the VGT not working as expected?

I have a 2006 Fod F250 with the 6.0 Diesel, I just got it back from the shop after doing Ficm, Injectors, Glow Plugs, Glow Plug harnesses, and brakes. I have driven the truck about 200 miles and got it back to the shop and parked on a hill and rewired the 7 way trailer harness. Now it will start for a second or two and then die. I checked all fuses(dont know how to check relays), pulled DTC and got a low fuel pump voltage. I pulled the IDM relay and was getting power to 2 of the 4 terminals and plugged the relay back and was getting power to 3 of four terminals(not sure if Im spose to have power to all 4), not getting power to the IDM 10 amp fuse in engine compartment either.

I have a 2006 f250 6.0. the truck has 101k miles and to this point I have had zero issues. I am having trouble loosing power after running at highway speeds. Once I stop and begin to accelerate the truck looses power for a few seconds ,Belches smoke and begins to operate normally. I had an egr code, so I replaced egr and the problem persist. It is intermittent and does not happen if I stay under 50 mph.

Just bought a 2006 F250 with 6.0. A week or so ago, it surged once at idle at a light. Sort of felt like someone bumped into your rear. It has gotten more frequent over the last week or so. Now it does it often. It tends to rev up and then back down again over and over. Then it will clear up again. My brother said his 7.3 used to have a similar problem (as did quite a few others apprently) and it was the Cam positioning sensor (CPS). Where is it located?

I have a 2006 f-250 6.0. About 2-ish months ago, it started revving up while I was parked and hooking up a trailer. It ended up needing an ICP sensor and pigtail wires. Was fine after that until around 10 days ago, it died when I was driving down the road and wouldn't start back up. That time it was the IPR. Got it back Friday, drove home (40 min) and didn't need to drive it until today. I fired it up, and we're back to the revving/surging. I decided not to take it on the road, really tired of being stranded. Could it be the icp again? Something else? I'm so tied of throwing money at this thing.

My 06 currently has 296k miles. 3 years ago I put a lot into her. Dummy plugs, stand pipes, STC, hg,studs, oil cooler, bpd egr cooler. Cleaned spool valves and fresh o rings in injectors. (Alliant) plus a lot more that I can't remember. Ran very very well after all that.
Fast forward to a few weeks ago. Driving down road and truck died as I let off pedal to slow down for turn onto my road. Took about 7-8 tries to get started back up. Icp was reading in the 300's until it finally started. Made it home. Shut it off. And started right back up.
Few days later truck died again same way. Let off to make a turn. Several attempts to restart icp was in the 300's again. Once it started building 420ish it sounded like it was firing a few injectors and slowly started running. The next time it happened the same way but when I got it back running I eased to my inlaws like less than a mile. When I got to their house and pulled in and went to back up to turn around the display on dash said low oil pressure and started missing a little. So once I got home started researching.
A few days ago I pulled out the low pressure oil regulator to check it out. It was clean but did have some mild scaring. I used some fine scotch rite and smooth it out a a little. It moved freely in the bore so I put it back together. Then pulled the oil filter cap off to check the little black valve. I noticed the filter was not dripping with oil like normally when I change the oil. And yes it's motor craft filter and cap. It checked out ok. Press it down and turned engine over and it filled and held. Let off of it and it drained.
Next I air checked the high pressure side. Applied air and waited until I could hear the air (IPR still open) then closed the IPR. Couldn't hear any leaks. Just a very very minor his and couldn't pin point where. So I went ahead and went to dealer and got new stand pipes and plugs. And ordered new print set for injectors. Pulled injectors and didn't see any smoking guns. Replaced prongs, stand pipe and dummy plugs and put it all back together. Cleaned the injector cups and hold down bolt holes. Torqued injectors to spec.
Got it all done and rotate motor by wire next to heater blower to assist prime system. Tried to start it up and it took two tries but fired right up and sounded smooth as hell. After it idled a few minutes I saw a haze from exhaust. It smelt just like fuel. A few minutes later started idle a little rough. Gave it some go pedel and it was rougher at about 1600-1800rpms and couldn't feel it above 2k. Got my laptop out with AE and done balance test. Did not show anything. No codes either.

2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.

Well, I've read a lot of threads on this problem! Try to do my own repairs, so I'm learning and not spending a lot of cash at repair shops.I have an 04 6.0 Super Duty Crew. Starting running rough on way home. Pulled over ,then it died.wouldn't start. Had towed home. Replaced ficm circuit board. No start. Replaced Harness,
icp...... ipr Sensors. Still no start. I noticed there is another circuit board inside ficm. Should I have bought the whole ficm unit?

I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.
So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .

I have a 99 f-250 with about 250k miles. Truck is completely stock. It recently has developed a problem where when I start it in the mornings it surges at idle, 200 rpm or so. Sometimes it tries to die and did once but started back up. When driving it continues to rev itself up and is jerky. It runs rough and sounds like it could be missing on a cylinder. At other times it runs fine just like normal. Yesterday morning it started with these symptoms so I put in a new ford CPS. It ran great for about 100 miles that afternoon. This morning it started back with the same symptoms. The SES light stayed on longer than normal when I started it, but it went off. I don't have a scanner.
I thought it might be water in the fuel because this started the day after I filled it from my transfer tank. But the water in fuel light has never came on. I put a new fuel filter on it but it made no difference. Have pulled filter three times looking for water but never found a drop. Also pulled several buckets from the bottom of my transfer tank but found no water there either. Where to look next?
