Ford 6.0L Power Stroke Diesel :: 2003 - Loss Of Power - No Boost On Acceleration - Vibrates?
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.
Ford 6.7L Power Stroke Diesel :: Turbo Boost Will Jump To 10 PSI At Moderate Acceleration
I'm relatively new to the 6.7 engine , I have a 2014 F-350 SRW with aprox 51,000 miles on it. Normal driving I see about 8 to 10 psi of boost even under moderate acceleration although at times it will go to about 18 psi at WOT and it does this with heavy loads. At moderate acceleration the boost will jump to 10 psi quickly but immediately stop there and sometimes as the RPM"s increase boost pressure decreases. Only issues I have had with the truck was a clogged EGR cooler.

Experiencing a squeal under hard acceleration at 3000 rpm with roughly 20lbs of boost, not present before and not present after 3000 rpm. light acceleration to 3000 rpm does not create sound, as well as turning 20lbs at a lower rpm (higher gear with throttle input). Truck has an EGR delete, EGR delete up pipe. EGR valve is still in place and plugged in. Truck did come with a banks six gun, so does not have EGR delete tune, however no trouble codes are present. What to check?
View 9 RepliesFord 6.7L Power Stroke Diesel :: 2011 - Power Loss - No Boost And Codes?
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?
Ford 6.0L Power Stroke Diesel :: 2006 F350 - No Boost And Smoke - No Power At All?
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.

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 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.
Ford 6.0L Power Stroke Diesel :: 2005 - Low Boost No Power
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
Ford 6.0L Power Stroke Diesel :: Brake Pedal Dead - No Boost For Power Steering - Hose Leaking?
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.
Ford 6.0L Power Stroke Diesel :: Low Power Before Boost Kicks In / Idling Rough With Blueish White Smoke Coming Out Of Exhaust
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???
Ford 7.3L Power Stroke (1999-2003) :: Typical Boost Pressure / Mostly 0 Unless Under Acceleration
I just recently installed a CTS2 Insight and wondering what the typical boost pressures I should be seeing without a load just normal driving. Right now I am seeing mostly 0 unless under acceleration then it goes up to 10 psi if I floor it I am getting 15psi.
View 14 RepliesFord 6.7L Power Stroke Diesel :: Boost PSI Between .80 - 1.25 At Idle?
Recently I have noticed my psi reading on my tuner hovers around .25 to .35 in the morning right when I start my truck. Normally it reads zero or is in the negatives. After driving around and stopping at red lights it will hover between .80 and 1.25. Now, I know that not a lot but its not what it normally reads.
Last week I went off road and my exhaust took a hit and loosened up and caused a small leak near the rear axle. I unbolted it and for the most part fixed the leak minus some alit air flow coming from the slits in the pipe. I'm not getting any codes and haven't noticed any decrease in performance. It does however seam to slow down quicker when I let off the throttle. I'm running an SCT X4 with dpf and erg delete and have a S&B CAI.
I called a performance exhaust shop and the tech said a small leak shouldn't cause any issue like that especially because its so far back. Another respectable vendor told me it might be that my vein are stick.
Ford 6.7L Power Stroke Diesel :: Decrease In Low RPM Boost
after my DPF delete and fl0-pro 5" install, i've noticed a slight decrease in lower rpm boost. with the tune i have i can still get it wound up, but it takes a little "gettin on it" to get there. i miss the little bit of boost i had from stop lights and what not, or even cruising at 50 with a slight increase in fuel. i don't want to have to have it downshift in order to spool the turbo to get me that slight uptick in power.
i've heard differing opinions - "stock turbos need the 4" for more backpressure" ; "5 inches is great, b/c you could always use a couple extra inches" ; "there's no difference between the two, but you don't NEED a 5 inch until you're at 1k bhp".
i've got the 5" setup on there... that's that. how can i increase the reaction of the turbos? i've read about a wastegate adjustment (tightening), but not sure i'm ready to undertake that in the driveway, and i don't have access to a lift. nor am i sure this will correct my "issue." (i quoted it, b/c it's not really an issue, it's just a personal preference that i'm wanting to adjust to make myself a little more happy with the performance of the truck)
Ford 6.0L Power Stroke Diesel :: 2004 - Loses Power / Acceleration - Electrical?
So the 04 is rolling down the road when the cluster gauges ping, the truck loses power/acceleration but the radio never goes out. Have a new alternator and batteries passed a check. It has done it three times. We are 1100 miles from home. OBD and cigarette lighter fuse was blown as well.
View 10 RepliesFord 6.0L Power Stroke Diesel :: No Boost - Won't Shift Properly?
Ok so I just put an egr delete and a new oil cooler in the truck. Everything went pretty well but when I was going for a test drive I'm not building any boost. I can here the turbo whistle like always but there no power and none of my gauges register boost. Also, the transmission is shifting funny I don't know how else to explain it but just not right. Now I don't see/smell any exhaust leaks and can't hear anything too wierd in that department. I checked the intake and the intercooler tubes I think their called and all good there. However, I did break my map sensor post off my intake during the install . So my map tube was just open to the atmosphere I didn't plug it or anything. Could that be the cause of my woes? Is there any thing I can do to alleviate the issues I'm having with the map? Can I just plug it until I fix it? And is there anything else to check on my turbo?
View 14 RepliesFord 6.0L Power Stroke Diesel :: Boost Read At Idle?
My question may be unique -- I cannot find anything about this -- at an idle, what should the boost read? Sunday at WOT I saw 28.76 -- but at idle it generally reads 0.1-0.4 -- bounces around a little -- but is that about right? Also, at WOT and 28+ boost what should the VGT read? I really am trying to sort out what this information is telling me -- not is that normal or average but what is ideal and what represents a red flag -- cut the truck off you have a problem kind of numbers.

View 3 RepliesFord 6.0L Power Stroke Diesel :: Lower Boost After EGR Delete
Some people say it's normal to lose some boost after the delete, some say it's not and you need a tuner. Before the delete, I could regularly see around 28-29 psi on the factory gauge if I jumped on it. Now, I see about a max of 20-21. I have no leaks that I can find and the truck runs just as it did before. I still have my EGR plugged in laying on top of the engine and don't have a check engine light-yet. Is there a definitive answer as to how to fix this or is it really considered normal to lose that much boost after a delete? I don't really want a tuner because I'm not looking to add HP, but if that's what it takes, then I need to save up. I also read somewhere it can depend on the strategy.
