Ford Super Duty (1999-2016) :: 2001 - Loud Thud And Again Thud Then Drive Normal?
While driving my 2001 F350 7.3 today running errands it started to have a real concerning issue. Once I slowed down back into my neighborhood it would make a thud, then feel like someone was pushing the brakes (even when i gave it gas). Then it would thud again and drive normal. I'm worried its the transmission getting ready to go. Any input?

The EMS service in the county next to ours lost one of it's new trucks for a few days on Tuesday. While going on a call, the engine made a tapping sound for only a few seconds, then a loud pop and shut off. Ford dealer went and picked it up and took it in for evaluation. VERDICT: Broken rod and cracked block. I have to say, this is the first I've heard of a 6.7L having a problem like this in our area.
Ford was really interested in this engine, as a new one is already on the way and the old one is to be shipped back for complete breakdown. So far, the Director and County Manager have been impressed with Ford's response to this problem. Dealer has told them the truck should be ready by the middle to end of next week. If I hear anything else, I will let you know. Any engine can break at any time, I'm just glad they are moving quickly to rectify the situation.
Ford 6.0L Power Stroke Diesel :: Hesitation / Chugging And Bad Smoke
So lately I have been having issues with my 6.0 smoking, hesitating, and chugging. It seems worse when the vehicle has been idling for a minute or two (as in at a red light) and when I depress the accelerator it starts to move, but chugs and sputters, spurting light gray smoke, then the boost hits hard, the truck surges forward, leaving a massive cloud of smoke behind, then seems to run fine until I come to a stop again. I got the usual EGR codes, so I cleared the codes, pulled and cleaned the EGR valve of all built up soot and carbon, and reinstalled it. It seemed to run okay again right after doing that work on it, but then started acting up again this afternoon.
Shot the same codes for EGR (P0404, P1335). I cleared them again, and it continues to drive like crap. Other than EGR that I can look into? Or will I need to pull and clean the valve again tomorrow when the sun is up? At first I was thinking I might also be having fuel injector stiction issues, possibly turbo vane stiction issues, maybe FICM issues, but it's only feeding me codes for EGR.
Ford 6.7L Power Stroke Diesel :: 2011 - Hesitation Or Lag At Takeoff
I'm taking my new to me 2011 KR 6.7 I've had it 1 week, to the dealer tomorrow to get them to look at the hesitation on takeoff. I have read on here that not all trucks are doing it. There is 25500 miles on it and have been averaging 15.3 mpg empty, is this about normal for what people are seeing? I'm running the 3.31 gear ad I thought I would get better mpg. This truck was built in Feb. of 2011 would it have the 400/800 settings or would it have to be flashed?

My truck is developing a hesitation or a miss when accelerating. It only does it in the beginning of accelerating like when just starting off from a stop. Seems like its more noticeable with the more I get on it. If that makes any sense. When just lightly accelerating it doesn't do it, like going slow through town from light to light. But when I give it more is when I feel it. It seems like it only does it before the turbo kicks in and it puts out a little smoke too only before turbo kick in. After that it runs good with no noticeable miss or anything. WOT runs feel good after it clears up. Its just when first starting out with anymore that 1/4 throttle I can feel it.

i bought a used 2011 F250 and really like the truck and there is no comparison when towing the trailer.
1.) I've noticed the truck doesn't shift smoothly from 3rd to 4th. Under light acceleration the RPMs climb, then drop slightly, then climb, and finally the truck shifts into 4th gear. It's almost like the truck wants to shift but doesn't. I believe a selenoid was replaced on the truck.
2.) From a dead stop, when pushing slightly on the gas pedal there is a slight hesitation or unresponsiveness with the truck wanting to proceed forward.
Ford 6.0L Power Stroke Diesel :: Intermittent Bucking / Hesitation Up Hills - No EGR
When I am on the highway, my 2005 Excursion (6.0) will hesitate/sputter/buck intermittently, usually between 70-80mph/ 1800-2200 RPM, but especially triggered by hills and inclines. Each sputtering episode usually lasts about 5-10 seconds and then will go away for minutes at a time. Does not sputter upon take off or initial acceleration. There is no smoke of any kind. Just got it out of the shop where the mechanic replaced ALL 8 injectors and the fuel pump, as well as flushed the fuel lines, and new fuel filters, and oil change (2 injectors were bad, but there was metal in the fuel filters, so to be safe I replaced all of them - ALL OEM PARTS for everything, including filters).
The week before, I had the IPR valve replaced. Also, recently had the back pressure sensor replaced and the EGR was deleted - and turbo cleaned when the EGR was deleted last month. I also tried unplugging the ICP sensor to make sure that wasn't the issue. Dropped $6k into this thing in the past month and about to lose my mind (and wallet). All research points to either clogged EGR or bad fuel injectors, but both have been addressed, so I am not sure where to look next. No current codes showing up. No signs of leaking oil.
Ford 6.7L Power Stroke Diesel :: Hesitation / Bucking When Going In The Upper 20s / Lower 30s
Have just about 1,600 miles on tuck born on 12/14/11. Love it, but.. When going slow in subdivision I am getting some hesitation/bucking when going in the upper 20s/lower 30s. When I feel it I look down and I am usually in 3rd. Is this the transmissible thing? When it happened Sunday it felt like it was going to die. If I start off with a quicker start (to get to highway speed) it shifts fine. It just started the last few weekends......
View 14 RepliesFord 6.0L Power Stroke Diesel :: Stuttering And Hesitation Starts At About 1500 RPM / Go Away At 2000
I've only owned a 6.0 for about 10 months now. I have a 2005 SCab FX4 with 125,000 miles on it. It has an Airaid cold air intake and MBRP exhaust without a muffler, everything else is stock. The stuttering/hesitation starts at about 1500 rpm, is worst at 1600rpm and seem so to go away at 2000rpm. It also seems to hesitate when I barely press the gas pedal while driving. Based on other fuel issues with other vehicles, I would assume this is a fuel problem, but am not well versed in the 6.0 engines. Fuel filters were said to be good by the dealership about 10,000 miles ago. EGR valve was replaced last week. I'm not blowing smoke of any color, even at WOT. I was thinking an injector may be the issue, but I show no other symptoms besides the hesitation/vibration. I don't feel any lack of power when I give it full throttle. I would like to know a definitive way to diagnose the problem without going to the stealership.

Finally registered on this site after hearing good things from others who are currently on here. Been a 6.0 PSD owner since buying the truck since new in 2003-F250 CCSB. I have done regular maintenance on it and have had a good run until recently. Everything is stock on the motor and currently has 229 000 miles.
I will describe my current problem: I have borrowed my brother's tablet and have the following numbers from the Torque pro app. While trying to accelerate it now has a hesitation and seems to not have the power.
At idle: 630 psi HPOP, 24 % IPR, 47 volts FICM, ICP volts .1
Trying to accelerate on at highway speeds: 1230 psi HPOP, 83% IPR, 47 volts FICM, ICP volts 2.6
Also, sometimes when starting the truck it seems to rev extra high for a split second. My brother says I may have a high pressure leak on the system. What I should check first?
Ford 6.0L Power Stroke Diesel :: 2007 F350 DRW - Cold Start Hesitation No DTC / CEL
Recently I replaced the unison ring on my turbo, EBP sensor and cleaned carbon out EBP tube/upper part of motor. After doing so she seemed to run fine but not like I remember when I first got her. Plenty of power but ever so slightly off, only an owner would notice. Few weeks later she hesitates a little bit while she's cold in the morning. I let her run 3-5 minutes b4 actually driving but as u know it's a little while to get up to operating temp. Temps seem OK 190-200 EOT/ECT. Fresh oil/filter, air filter, coolant, EGR was cleaned out a little while back and EGR valve replaced 25k ago. I'm not sure where to look at this point...the motor has about 30k on it.
View 3 RepliesFord 6.7L Power Stroke Diesel :: Multiple Low Fuel Pressure Warnings And Hesitation At Low RPMs
So it looks like my lift pump (low pressure fuel pump and sending unit) is going. Multiple low fuel pressure warnings over last two days and hesitation at low RPMs. Not hearing pump run when I turn the key all the time but no issues starting. About 16,000 miles since last fuel filter change but picked up new filters today at dealer.
Asked about a fuel pump and he quoted PS401 and none available in Canada and had to inquire direct to Ford - 30 day wait on a part that will turn my truck into a brick if not replaced. Can't find a PS401 but I can get a PS 402 out if the USA in 5 days.
Any difference in these? Dealer is an idiot and can't even determine if there is a difference or too lazy to find out for me. I don't even know if I can prime the truck if I change filters at this point and this is a quick change job for me if I had the pump. Going over the system from back to front in the morning.
Don't ask about warranty. Just hit 160,000 KM on my truck.
Ford 6.0L Power Stroke Diesel :: Intermittent Hesitation After Stopping At Light / Stop-sign
Trying to troubleshoot a very intermittent (has happened on two different occasions during the last 1,000 miles) hesitation from a stop-light. I've been recording engine parameters (Torque application) on both instances as these have been during longer trips after a period of highway driving. 2004 Excursion, 112K miles.
This feels kind of like severe turbo hesitation (4 to 10 seconds trying to start out before it kicks in) but I don't think that's it. The turbo is a new PowerMax turbo replaced 5 months ago. VGT readings seem pretty normal. The EGR valve is new -- the first instance was with the old and the second was with the new. I've also recently replaced the EGR and Oil coolers (before this).
Here's what's interesting in the captured data though... Normally when I coast into a stop-light the indicated engine load stabilizes at about 40-50% and VGT moves to about 65% to 70% at idle. The two different times this happened (actually multiple times at stop-signs/light close to each other over 5 minutes or so for both of these), when I have coasted to the stop, the engine load increases from low values during coast-down (0% during freeway coast-down or 19-30% during other coast) up to 99.6% (or other similar high values) at idle and VGT seems to be full closed at 85%.
There is absolutely no response to the throttle in this situation for 5-10 seconds. I've either been goosing the throttle a bit or putting it neutral and revving it up first to get things going again. When it finally catches and starts accelerating with power, indicated engine load drops to 50-60% again and VGT opens up to 40-60% or so. None of the other parameters I've been capturing seem to read strangely during this that I recognize. No issues observed during cruise and power seems good. No pending DTCs or engine light.
Here's what the data points I'm capturing (once each second):
Boost
Calibration Input Volts
ECT
EOT
Fan RPM
FICM main volts
Fuel Injector pulse width
ICP
ICP Volts
IPR Duty cycle

Ford 6.7L Power Stroke Diesel :: 2015 - Shaking Under Slight Load Due To A Small Incline And Loud Diesel Sound
So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sneeze Like Hesitation Just Before Downshifts To Passing Gear
I have a 04, f-250, with a 6.0 liter engine. I have had the Cat removed and in the last couple months it has developed a sneeze like hesitation just before it down shifts to Passing gear, If I push my foot into the fuel it jumps right down thru the sneezing into passing gear. I have changed fuel filter and grade A cleaned my EGR valve. the only Codes it throws is P0403 and P0405.

My fuel gauge on my Sport Trac is nowhere near accurate. Ran out of gas the other day showing 1/4 tank.

I'm showing a PO191 fault code which says Fuel rail sensor.
Would that cause a gauge to malfunction?
Ford 6.0L Power Stroke Diesel :: Loud Pop As If A Hose Came Off And Power Loss
First there was a loud pop as if a hose came off and a power loss - don't seem to see any hose disconnected. Happened to me once and seemed to return to normal and then happened to my son. Have not driven since the last time. Both times pulling a boat.
Second issue has been going on since I got the truck - bought used apprx. a year ago - believe it to be stock. The time from pushing accelerator until actual kick in is very elongated - sometimes worse than others but very long on the worst side. Usually noticed when needing to pass on the highway. Once kicked in truck runs well.
Ford 6.0L Power Stroke Diesel :: Power Steering Pump Making A Loud Whining Sound
My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.
