Ford 6.7L Power Stroke Diesel :: No Power When Accelerate Quickly While Driving - Low Boost Until Restart
Jun 21, 2016
I was driving and went to accelerate quickly and had no power, checked the boost gauge and it had very low boost. Continued like this the rest of the drive, all gauges normal, no check engine light, not towing or hot. Got home then next time out it was back to normal.
Someting to be concerned about? Or just a computer hiccup. Truck is '13 with 66k.

I have a late model 2004 F-350 6.0 powerstroke. 182K miles. Auto Transmission
What happened. Condensed version
Left house, drove out to highway, got on highway. Everything feels normal.
About 1 mile of going 70mph, I notice I can no longer accelerate. after 1/2 mile, I begin loosing speed, and engine will not rev past 1000 rpm. I eventually pull over (another mile), put in neutral and will not rev past 1000. put in drive and start to idle to highway exit. it gets about another .5 mile and begin going up a hill when it completely dies. Will not restart.
No prior issues with the truck. Full tank of fuel.
What I have tested so far. Ficm 48.5 volts cranking. Icp .225V KOEO, .875V Cranking. LPOP is registering pressure on the dash. No Fault codes.
I have gotten it to start twice now, one time it allowed me to rev to 750 rpm, where i used 4 low to make it onto a trailer. second time would not rev at all. idling at 250-300 rpm.
That same night as it died, I drained the transmission pan/ TP filter and filled with 8.5 Quarts of Mercon LV. This is the first time I have done this since purchasing @ 161K miles. Everything seemed normal, no leaks present.
Also my buddy showed me how to enter the dash test mode and we cycled through these. Not sure if this is relevant.
So, What do I test next? I don't think its HPOP issue since the ICP is reading .875 volts at crank. I did unplug the ICP and it still would not start. I don't think its the injector side of the ficm because they buzz as normal with koeo, but this is a possibility as I don't have equipment to test. Egr valve is clean for age of truck.
Would it be possible that the Mercon LV knocked crud loose in the transmission causing it to fail/seize? would siezed tranny cause the engine to behave in this manner?
Fuel bowl on top of the engine was full of fuel. I have not pressure tested it yet as I can hear the pump running during key on.
could i have a bad crank or cam sensor?
Multi-injector failure?
Bad Icp with HPO failure?

Was driving back home from shopping tonight and my truck was making a lot of noise when I tried to accelerate. I noticed the boost gauge on the dash was stuck at 35psi but the MiniMaxx showed 0psi.
No engine light so I babied it home which was about 30mins driving and managed to accelerate slowly to avoid the engine rattling. I didn't want to shut it down and restart in case it wouldn't start again for some reason.
When I got home I idled until EGT was <300F like I normally do (it never went over 700F when I was driving home) and then restarted it. The gauges worked fine, MiniMax showed boost and the engine revved freely with no rattling noise. I haven't taken it out for a road test, I'll do that when it's daylight.
Bad sensor somewhere? I would think if the turbo had failed it wouldn't have been fine after a restart.

Occasionally when I'm driving, I'll accelerate and get a brief loss of power, then it'll pick back up, followed by a puff of white/blue smoke. This usually happens when the oil is over 120*, but not quite to full operating temps. It doesn't happen every time either. Only 3 times in the past week. Otherwise, there is a very faint haze of white smoke that seems to be constant. It is very difficult to see unless against a dark background. Oil level is good, I check it once a week, no rising or lowering levels.
I pulled the EGR yesterday, all good, although a tad dirty. Cleaned up no problem. Haven't had a chance to do a bubble test yet. There are some DTCs, but I can't remember off the top of my head what they were. I'm about to go clean the inside of the truck, so I will pull those and update in a few minutes.
Truck has about 148,500 miles.
Torque Pro lists these codes: C1145, P0299, P0677

My f350 6.0 has seem to have lost its power, while I was driving home it would only accelerate at one constant speed, and driving up hill it would not accelerate at all, I also noticed an elevated exhaust temperature.. There are no warning lights or dash lights indicating any problem.....

So I have a no start on my 6.0. I was driving and went to accelerate and had no power, pulled off of the road and was idling rough, I checked for fuel leaks-none. I put it in drive and engine cut off and wouldn't start again, changed the ICP (threw a code) still nothing, FICM is good, ICP is 950 psi at cranking, IPR is only at 54%. I'm at a loss of what to do next besides looking at the IPR, and I do not have the equipment for a leak test.

My Brothers truck died while driving and won't restart. I am going to be getting IDS on it tomorrow night and just wanted some feedback on things to watch. I am planning to watch FICM sync, ICP pressure, IPR %, FICM voltage, and fuel pressure(not in IDS). Anything else I should watch while testing?
Edit: this truck is a 2005

My 2003 6.0 has a coolant leak. It leaks slowly while not running and more quickly while running. I have about an 8 mile drive to work every day, I can make it there and back without having to add coolant but I'm cutting it pretty close by the time I get home. In short I go from the max fill line to bone dry in about 24 hours.
With the truck running I can see water getting slung around all over the front of the engine but the majority of it seems to be coming from around the two larger pulleys in the middle. I've read that this can either be the crankshaft seal or the water pump, any way to know for sure? Any other possibilities?

When I'm driving sometimes it will pour black smoke and make no boost, and then the next time I get on the throttle it goes make to making boost like normal. It has the following thing done in the last 50k. I have a 2006 f-250 lariat FX4 it has the following mods:
EGR delete,
Powermax Turbo,
Rudy's Diesel Up Pipe,
4" Turbo Back Muffler Delete,
New For Injectors,
Blue Spring mod,
Gear Head Tune,
S&B Elbow And S&B Cold air kit

I drive an 06 f350 with a 6.0 diesel. My truck has quit on me twice in two months. It lost power then stalled and would not restart. I had just changed fuel filters but checked them anyway to see if they were plugged. They looked clean so i put them back in and the truck fired up. It ran good then two months later it did the same thing.
I noticed I could not hear the fuel pump so i pulled the cap off if the top fuel filter to see if there was fuel in it, and heard air being sucked in (or pushed out?) as i loosened the cap. I put the cap back on then turned the key and i could hear the fuel pump working. I waited for glow plugs and it fired up. Is my engine getting vapor locked, or sucking air? If so then why would it only happen every now and then instead of continuously?

I have a 2007 F350 6.0 Diesel. Truck starts and runs great for about 10 miles and then loses power and slows down til it dies, it does this without any kind of warning and does not rattle or anything. If i let it sit for about 15 min it will start right up and drive fine for another 10 miles or so and do the same thing.
It did the same thing in December but would not restart at all and the ficm was the cause at that time so i went ahead and replaced the ficm just to eliminate it. I also replaced the fuel pump and the ipr and icp valves are good. The only engine code has to do with the fuel level sensor and that has been on for a year. The egr was recently replaced, the hpop is putting out the psi that it is supposed to and there are not any internal air leaks.

Truck = 2011 F250 150,000 miles, no modifications, stock.
Truck lost power yesterday, no boost, and no codes. When driving on Friday, I started moving from a red light. The truck seemed very sluggish. Then I noticed it downshift going up a small hill that it never downshifts before. I looked, and noticed the turbo gauge at 0, no boost. I pulled over, turned it off, then restarted it, but still no boost, and the truck is very under-powered. I looked over the area, and do not notice any leaks, also no leaks underneath. I hooked up my OBD reader, and no codes., the boost gauge is on zero, and the truck has lost significant power. I no longer hear the turbo spooling.
I have spent the past several hours searching sites and forums (Started with FTE ), and it seems that most believe a restart of the truck has solved it for them. However, this is not the case for me, a restart, even after letting it sit overnight did not resolve the issue.
I did see one reference that replacing a NOX sensor solved their problem. This brings up some interesting truck history. Back in June 2017, my truck threw the following codes, P207F and P20EE.
P207F - Reductant Quality Performance
P20EE - SCR NOx Catalyst Efficiency Below Threshold (Bank 1)
The message said I have 200 miles until reduced power. Since it was a Friday, not much I could do at the time so I let it sit overnight, and then the next morning the message was gone. I plugged in the OBD reader and cleared the only remaining code (P20EE), and its been a very happy truck until yesterday.
So my question, can a bad NOX sensor cause the issue of loss of turbo boost, with no codes? Is there another possible cause?

I have a 2006 f350 4x4 dually 6.0. The other morning when leaving for work I hard a loud air noise, like a jet. It only happens when the motor is trying to create boost. I have NO boost. No smoke. If I push the fuel pedal past 1/4, nothing. Its like its stuck and no more power at all. I have changed the boot from the turbo to the intercooler pipe. (looked like it had cracks in it). Checked the cold pipe, no cracks seen. Check the exhaust clamps, into the turbo, they are tight. The turbo is seeping oil around the seal. I took the inlet, fresh air, pipe off. Check the turbo spool for looseness, fins, spun the wheel, ran the engine and watch to wheel. Seen no issues. Where to go now?? No coolant leaks, no oil leaks.

So about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?

I have an issue with my 6.0. I was running the extreme street tune from IDP for the past 2 years now and recently purchased the xtreme X tune from IDP. I loaded in the tune and had low boost, low power and horrible acceleration. Max boost i would see is about 10psi and it would take about a solid minute to reach highway speed when merging on the highway. I went back to the stock factory tune and have the same issue. No boost leaks from the boots or pipes and no check engine light. What is going on?

I have an 03 6.0 Power stroke. My problem all started the other day when I started to occasionally not get any boost on acceleration and lose of power and a lot of vibration like it's about to cut out but it got worse now today I drove it about 5 miles into town when I got to town I noticed a rough idle I got gas in a gas can not in the truck. I got back in to leave and I had absolutely no power at all the truck stalled out and it was very hard to start finally got it started and it runs really rough almost like it's going to shut off.
So when I started driving I would only make it about a mile or so with out it chocking out and having to let it site for a minute or two and start it back up and go another mile or 2 and have it do the same thing all the way home all the time I have vary little boost if any at all except for when I first pull out now oil pressure is good and engine never over heated some of the codes I have is an EGR code and a contribution balance code for several cylinders I was thinking possibly a maf sensor or a clogged egr not working right.

Having this problem, what to do to correct it? There is no hole in the boot and this just started about a year ago. Does not do it all the time.

I've got an 05 EX 4x4 150k miles. Stock tune, EGR delete only ....
Driving along and everything was good plenty of boost no power issues. Got off the freeway and truck just stopped making boost. So I messed with it for a couple days. Cousin with a Mac scanner flaked on me so I was stuck using Edge gauge cluster and trying to trouble shoot.
NO CODES, No smoke, EGT's rise and truck seems like it is lean. Boost has fluctuated between 4psi to 11 psi. What should MAF be at idle?
ICP has been consistent with whatever boost levels were being made.
FICM 47.5
New MAP tube/nipple cleaned
New MAF
Clean Air filter
New fuel filters
VGT actuates
Accel ped in spec
Turbo spins free
New hot side CAC boots

Is there one thing that when broken makes both the steering and brakes lose all power? Does the power steering and hydroboost share a pressure source?
My brake pedal is dead and I get no steering boost, but the master cylinder and PSP are full of fluid. Do I replace both, or replace one first to see if that fixes both? Or could it just be a hose leaking? Not sure how to diagnose this one.

I just looked back and it has been since July 7th that my girl has been sitting in my shop. Well this past weekend I finally got her back together and started. It took a while to build pressure but she finally came to life..
While I am thrilled that she is running again i have low power before the boost kicks in and is idling rough with a blueish- white smoke coming out of the exhaust. Once i kick her a little she will get up and go but I've never had the smoke before.
I'm thinking maybe a bad injector???

I have a 2004 F-250 with a 6.0 and am having a serious issue. The truck has about 240,000 miles and has been great until now. About a week ago the truck was running great and had plenty of power. I decided to wash it with my pressure washer (did not spray under the hood, however I did spray in the front wheel wells and underneath the truck). About 5 minutes after washing the truck, I took it out for a drive and noticed when I really got on the accelerator the truck would not want to try harder and motor got very quiet. Really all you could hear was the turbo whistling. Over this past week the problem has gradually gotten worse... a few days ago I had to feather the pedal in order to go up hills. If I gave it more than about 1/4 inch of accelerator, the motor once again would get quiet and the truck would start to slow down and would not want to work.
However, if I let up and only gave it a small amount of accelerator, the motor would sound normal again and it would pull up the hill. Today, I can do nothing more than idle back and forth in the driveway because the motor gets quiet and the turbo winds up if you give it even the slightest amount of accelerator. I have no idea if it's a coincidence that this happened after washing the truck, or if maybe there was a sensor that was rotted and about to die and I finished the job with the pressure washer. I already replaced the egr valve and have been running tons of Howes diesel conditioner and anti gel through it. The injectors were replaced about 50,000 miles ago so I'd hate to think it was them. The truck doesn't smoke at all either.
