Ford 6.0L Power Stroke Diesel :: 2006 F350 - Bucking / Rough Running
Mar 23, 2017
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?

Truck is running bad when first cranked in the morning, is bucking and running rough until warmed up, think the oil needs to be changed and which additive is better the archoil or Rev x?

Since our weather has returned to the cold side......my truck has started bucking and hesitating at 45 mph with EOT @ 130 and ECT @ 140. I can gas on it and it will clear up/let off and it would start up again once it gets below 50 mph. Once the deltas reach 150+ it clears up completely. Its never done this until this week. FICM volts are steady @ 48V. What is causing this or what to look for?

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 buddy at work who has an 04 f350 6.0 that is running very rough. we put a scanner on it and disabled the injectors and 1,7,8 have no change. He checked the FICM voltage and is getting 48 volts on crank and run. He checked the wiring for anything loose or rubbed but nothing seems wrong.

I just bought a 2007 F350 6.0 two days ago, so I was giving the truck a good wash today using a electric pressure washer. The engine bay was pretty dirty so I decided to take some soap and a brush to it. After cleaning it I let it sit for a while in the sun to dry. (engine was stone cold). After it had completely dried out I go in and it cranked right up. I let it idle for a good minute-minute and a half put it in drive and pulled away slowly, right when I touched the accelerator it started running rough, so I popped it into neutral and let it idle for a sec but it was still running really rough so I cut it off not wanting to damage anything worse.
I let it sit and tried to start it again, it just turned over and over. I checked the oil level it was good. So I pushed it back into my driveway to figure it out. I took ICP connector out and tried to start it, just turned over and over. took fuel filter out it was just replaced 2K miles ago it looked a little dirty but not super bad. I put that back in. took icp out again and tried to start it and it started but ran super rough and was dumping black smoke out.
I checked back all ficm connectors and they were all connected. I haven't checked the voltage on that yet, but plan to do that tomorrow. the previous owner had the ficm go bag about a year ago and he sent it off to ficmrepair.com and they fixed it for him. also he had the stand pipes and dumby plugs done as well as the stc on hpop. im kinda at a loss on where to go now other than to check voltage on ficm.

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...

So, I was on my way back home driving through the middle of nowhere Utah late at night, when I had an injector tip crack. I was able to identify which one and unplug it so I could get to Grand Junction, CO (about 350 miles away) where I have family. After a power nap I started calling parts stores and found an injector from Advanced Auto Parts (I couldn't find a motorcraft reman, but I was restricted for time). Installed it and all seemed good so I hit the road again. However, nothing changed. It still had the bad miss (rough idle, jerking/bucking when the torque converter locks up) just like when I had the injector unplugged.
The truck is an early 2004 6.0. It's the number 4 injector. I finally got home and hooked up my AE scanner to discover a #4 injector circuit low P0270 code and circuit contribution/balance fault P0272. It's definitely missing because disabling it has no effect. This could be a loose connector at the injector or FICM, because I can't afford another injector right now.

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

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?

2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.

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 have a 6.0L Powerstroke with about 74k miles. I've owned it about a year. this weekend while driving on the highway at about 55mph i slowed to make a turn. As it came to idle i noticed it was idling real rough. As I accelerated it barely got across the highway. I went to where i was going and let it idle but gave it gas and raised the rpm's to about 1k.
I was concerned it was going to die. As I left it seemed to be better but as i drove it would get real rough and then go away. I accelerated a couple of times engaging the boost and it seemed to be better. I made it home and parked it, but i let it idle before i turned it off.
Now it will not start. it just cranks. everything is pretty much stock. i replaced the fuel filters back in december and also did the blue spring upgrade. I have a OBDII but i didn't have it with me so i wasn't monitoring at the this time. What should be my next step?

My truck is a 2005 f350 6.0, all stock except for an egr delete and 4 inch cat back exhaust. I recently did an oil cooler replacement and egr delete, resealed all 8 injectors, and fixed some wire chaffing at the FICM. it's running great with the exception of idling. It seems like it's idling low but the gauge stays at 750. If I hit the high idle switch, it does fine. Red lights are stressful because it shakes and sounds like it's going to die but never does. I'm posting screenshots of my Torque pro.
I have a SC2 as well but I honestly like Torque better so that's what I use most. I know my ICP is low, but 8 don't know why. No oil in the connector, and no change when I unplug it. The ICP sensor may be a month old with 1000 miles on it. This was taken at a hot startup, sitting in park. When i say hot, I mean I had driven about 60 miles. This is sitting still in drive. ICP voltage finally climbs over 1.0 when i get going about 15mph at around 1250 rpm. The second pic the ICPV is actually higher than normal. It usually stays at .8 until I give it gas.

Did my oil change last night and filter swapped both fuel filters on my 04 f350 started it up last night drove it a little bit and she was fine. Went to start her up this morning and she was pissy so I drove her a bit once warm and she feels like there is a dead cylinder maybe??

I was towing a trailer about 600 miles truck was running great, pulled in for fuel and truck was running rough, refueled and was on my way then when going down a hill (Idle) it just quit, had to tow remaining 200 miles.
After reading the forums I replaced the ICR (ICR screen was damaged) Truck now starts but its very loud and missing like crazy. and surges if i give it a little gas. codes 0268, 0281, 2284, 2288 I also replaced the ICP.
should I replace the injectors? what causes this?

My Excursion got 4 new injectors a couple weeks ago and when I got it back, it was running rough. My mechanic told me it was going to take about 100 miles for them to break in.
300 miles later and it is still running rough. So I opened the hood, took a look around and saw this wiring harness unplugged. Where it goes? Youtube video shows where the harness is [URL] ......
Also, my truck has been shaking violently at 50 miles per hour, unless I hit tow haul, then it is moved up to 60... I am assuming its connected some how to that wiring harness being disconnected.

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?

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...

My truck was running rough when cold, I went to check the ficm voltage while wife was cranking and coolant shot right into the ficm and cooked the sumbitch. Stop laughing that stuff happens to me all the time. Anyhow, got a new ficm and truck wont start. Starter kicks out after a few revs. I ran my own solenoid wire to the starter and it cranks just fine. ficm at 48.5 koeo and cranking, icp 1100+, ipr from 14.8 to around 40%, ...
It takes a few seconds for the cam/crank to sync but it does. I changed the fuel filters and primed it, Got new batteries, and threw a crank sensor for s+g. With the key on and me cranking it using the solenoid wire, it almost starts. But from the key it will kick out after a few seconds. All fuses and relays are good. I hear the pcm also controls the starter, could that have cooked when the ficm went or would it blow a fuse? Diagnosing using a scangauge2 ....
