Ford 6.7L Power Stroke Diesel :: 2011 F350 - Losing Power - Rough Noise - Vibrating?
Aug 18, 2011
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 have a 04 F30 4x4 with a sick 6.0 power stroke. It has 230k on the mileage and ran good. I was driving at speed when she started missing like it had lost an injector and loosing power. The RPM's dropped under 1000 so I had to pull over off the highway. When i pulled over and put it in park it shutoff. Tried several times to get to start but after 10 minutes it started up. I drove about 2 miles and it started the same process. This went on 2 more times before I was able to finally limp home the 40 miles.
It never shut off again but ran very poorly. I put a new valve in and when I tried to start it just mad a pound clunking/clacking noise. The repair shop put a starter in it because it had stopped engaging and was going to ruin the fly wheel. I looked at it and it was eaten up pretty bad from trying to get the engine to turn over. So now all it will do is a single clunk and will not turn over. He says it could be a bad injector that flooded a cylinder or blown up in the bottom end. He did take serpentine off and still no go.

I've got a 2011 F350 Lariat crew cab and when i get up to 75 mph with a cross wind, there is a whistling noise. it sounds like a turbulent whistle as if its blowing across the ribbed portion down by the wipers. I tried to get audio but for some reason my phone wont pick up the noise, but its extremely loud at times. Sometimes it will wake up the kids if they're napping in the back seat.

I have a 2016 350 dually with 6.7, with 2,200 miles. I was pulling my 11,000 LB travel trailer on fairly level ground, major interstate going 65mph. Noticed I started losing speed down to about 58mph, then started decending a long 5-6% grade, at this point I was running at 3/4 throttle to maintain speed. It felt like something was binding like the rear or engine was seizing up. No codes, all temps were fine. Transmission stayed in 6th gear, even at 3/4 throttle.
Checked trailer brakes, didn't seem to be dragging. Engine sounded like it was really laboring like it was tightening up. This lasted about 10 minutes, very slowly power seemed to return to normal but it was not noticeably changing. Fuel was 3/4, DEF was filled about 300 miles earlier. This truck since new feels like it has 150HP less than my 2011 F250 with the 6.7 I traded it on. Not sure what to do, if I take it back, if they find nothing then I'll get a diagnostic charge.

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 .

My uncle was pulling his fiver to the beach yesterday with his 2011 f-350 6.7. He lost power, the truck got very loud, and there is a very strong stale kerosene smell in the cab. Strong enough to require the windows be down for ventilation. He was able to limp on into the campground and has an appointment with the dealership Monday. The truck has 19,000 miles and is still covered under the extended warranty.

Currently truck is in the shop after having multiple episodes where it lost power. It has 47,000 miles on it. When pushing down gas pedal, just does not want to go. Very slow to shift through the gears and get to highway speed. Turbo was not there, and there was also a hard shift/jerking from 2nd - 3rd. Did notice the traction control sensor kick on a couple of times....which was just replaced since a hole rubbed through the wiring. (took it to Ford twice before they found the problem)
They told me today that the code generator said to look at wiring but they did not find anything (heard that before) and that the fuel is possibly contaminated with DEF. If that is the case, someone is messing with my truck! What I don't understand that if the DEF does turn out to be in the fuel tank, wouldn't we have the problem continuously and not intermittently over a month after driving thousands of miles and going through numerous tanks of fuel? We drive and average of 60 miles per day just for work, half interstate/city.

I have a 2011 6.7 F-350 Diesel. I bought the truck new and I've never had any problems with it until now. I have a SCT Chip & Tuner. It needed an update so I returned the truck to stock and a code came up on my dashboard that said "reduced engine power" which obviously I thought was Normal because of the modifications done to my truck.
I updated my tuner and returned the truck to a performance tune but this dashboard code will not go away. My truck isn't reading any codes and there's no other indication lights on. The truck has Normal RPM readings but 0 throttle response. No power at all...

I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...

I have a 2011 f350 that i bought with 30k miles on it and I now have 40 k miles. My truck will not go over 83mph it seems like its governed out there.. I have taken it to ford and they thought it was my key was set to max speed 80mph. but it was not and could not figure it out.. I have tried to disconnect the batteries to reset computer. I have not clue what is going on. I do have 35's (tires) on the truck with a leveling kit. But I have verified my speed only going 83 with ford and my own gps device..

The past month or two, my garage-kept 2011 F350 6.7 with 38K miles will shudder on startup for a second or two or three then runs normal. What would be causing that? She is my every day driver, but I don't drive her every day. Seems that the longer she sits, the rougher the startup. Last time I drove her was Monday. Started her up tonight to run to the store and she shuddered for about three seconds.

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 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.

Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.

Took my '11 F350 CC 6.7 Lariat with 31k miles on it into the dealer to have the tranny fluid leak looked at. I noticed this leak a few weeks ago as the bell housing was damp with fluid and the bolts heads on the underside of the poly engine oil pan were pooled with fluid. It is a very slow leak as I have parked it for 3 days and there were no drips of fluid on the ground, just collecting on the grid like pattern on the oil pan. Checked Fluid level and it is also full.
Anyway, the dealer put dye in the tranny fluid and told me to drive it for a few days. I took it back in on Monday and called this morning for an update. The mechanic informed that they ordered a new torque converter and some other parts to be "proactive" because he believes the TC is the issue. I asked if the cab would have to be pulled and they informed that all the work could be done from underneath. Glad I noticed this before the B2B warranty expired because this would have been expensive. I will be THOROUGHLY inspecting the entire vehicle from top to bottom before I hit 36k.

2011 Ford F350, 69K miles... Just started, at about 30mph. I am hearing a Chirp from the front, speeds up when I speed up and goes away with brakes or slow below 30.
Friend thinks its the brake warning telling me its time for new. Bugging me. Just started. Never changed brakes.

Just went out this morning to start my 2011 F350 diesel and the starter is doing a "chugging" sound. Not spinning the starter at all. Just turned 60,000 miles last week and this is the very first issue that I have had with the truck.
I have put a trickle charger on the battery on the drivers side, and plan to leave it on for an hour or so.
