Ford 6.0L Power Stroke Diesel :: Rough Loud Clink Down Under Even When At A Stop Sign
May 22, 2015
Have a 2004 F250 crew cab with the notorious 6.0L.. ive noticed what i believe is my tranny or maybe torque converter.? What happens is when i back out the drive way and the go into drive, i hear and feel a rough loud clink down under even when im at a stop sign.. I am a first time truck and diesel owner due to my field of work. Also it has a rought time starting in the mornings or anytime the truck is completely cold. Then after it warms up it behaves like it should. also ill get on the throttle and when i come to a stop, the idle is rough and slowly comes back to normal. ...???

A couple months back I blew an EGR cooler. My mechanic replaced it and oil cooler, when I got the truck back it was using coolant and on cold days below 35 degrees it wont start without a little shot of ether. I took it back and mechanic found a pinched o ring.T he coolant problem is ok but cold starts not. Now today truck was running fine then as I was pulling out of a stop sign I couldnt get over 40 mph, I pulled over and then tried to go but no throttle response,then died and wouldn't restart .I have no way of scanning, no dash lights came on. I am wondering if this is related another o ring or gasket,hpop ,fuel problem??? just replaced all the injectors and ficm a little over a year ago.where should I start?

So about 3 days ago I made a long 9 hour drive. No problems at all but I did allow my fuel to get a little lower then I normally do. About eighth a tank had 30 miles left on the digital read out. Stopped and filled up at loves where I always get my fuel. And off I went drove it down to 3/4 a tank and made it to my stopping point. Got in to go about 7 miles down the road and come to a stop sign and slowing down the truck died. I thought crap I forgot to turn off the auto start but never done that before. Stopped and stared truck as normal. Made it to my stopping point again. Headed back to the house and doing on average 55mph and truck surges like it wants to die but doesn't.
Rpms drop below 500 and it keeps going I get to same stop sign and slowing down again doing maybe 25ish and truck dies again as I have my foot on the break. Put in nut and started it right up and drive on home. Today went about same distance. Only this time I started it with key and was doing down other things while letting it run it just dies start it back up and take off get to where I was going and it surged or hiccuped so to say. Again started it once I was getting ready to leave and let it run for about 5 min and it died had the heater on as it was chilly out by the lake. Got in and restarted it and it was blowing cold air and had a diesel smell to it. Wife asked me if truck was going to blow up. Backed out of area and put in drive and made it 80' or so and truck died again doing about 10mph

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
RPM
Engine Load
MAP
Trans Temp
VGT Duty Cycle
EBP
EGR Commanded
EGR Error
Added today but not captured during these issues yet:
IAT
IAT2
Baro
Accel Pedal Position
Mass Airflow Rate
Mass Fuel Desired

The other day while at a stop sign in my e99 F450, I went to take off and stalled. I am not sure if the stall was my fault or not; however, it would not start. I turned the key on and the wait to start light did not come on.
The first thing I checked was the mini 30 amp fuse under the dash that controls the GRP and the fuel bowl heater. The fuse was good, and my heater has been unplugged for a while anyway. Recently my SES light came on with codes that said the glow plugs had low voltage for both banks. I have cleaned the wires a couple times and the light goes out but then comes back on after a minute or so.
I figured that maybe if it was a bad wire it finally went bad so I got jumper cables and started to try and jump wires. I moved them around and found that when I hooked one side to the positive battery terminal and the other to the small key hot wire on the glow plug relay, the light would come on and it would start. I left the cables hooked up and drove the couple miles back home.
After messing with it I figured I could run a new wire. I got a fuse tap, and went from the 30 amp mini fuse that controls this system anyway, and ran it up to the post on the GPR for my new keyed hot wire. The WTS light would cycle and it would crank, but no start. After some more messing around I decided to put both the original wire back onto the post with the new wire that I had just put on; after doing this it started right up. I took it for a test drive and a couple times the engine would act like it stalled, only for a split second. When looking down at the dash immediately after the tach would be at normal RPM and the WTS light would be on, as if I shut the key off and tried to start it again.
I suspect it is the original key hot wire that goes to the GPR. It appears that this wire also has a purpose, other then serving as only a keyed hot wire for the GPR. It has about 6 inches off of the GPR, then it goes into the harness. Where that wire goes? I will just run a new wire instead of having to dig through that harness... that doesn't look like something I would wish upon my worst enemy.

04 Honda CRV: I just had new rotors / pads / calibers put on my rear 2 tires because I was getting a loud creaking sound whenever I reversed or stoped at a stop sign. Most notibly I would hear it after the car had sat for a few hours as it's not happening a 100% of the time... Am I looking at joint or wheel well problems now? The loud creaking is still an issue...

I have really taken care of this 2011 SF Limited with the 3.5 V6 but it has always seemed to idle rough at a red light/stop sign while in drive. Is this common for all the 3.5 V6 engines? I run a fuel cleaner through it before every syn oil change and also use top tier gas. It drives nice but like I said, at a stop in drive it seems to run rough at around 500-550 rpm's.

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!

We have a 2002 7.3 f350 2wd this darn thing is now tripping me out. At first when ou start the truck its all good but when it warms up the idle is funky when you go to stop at a lite its like im power breaking and rough idle once stopped the idle is about between 800 and 900rpms at a stop really high idle but plenty of power on take off...

I have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?

Just bought a L/Certified pre-owned 2013 ES 350. I am shocked at how much the car vibrates and noise increases when stopped at a light or stop sign. I tried a 2015 ES 350 and the same thing occurs!! The dealership technician says everything is operating "to specification". This is a disgrace for such a high-tech, luxury car.

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.

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.

After my recent cooling system upgrade and power steering pump/HP hose replacement I am still hearing and feeling the power steering whine. I flushed the fluid and used Mercon V ATF fluid. I jacked the front end up with tires off the ground and cycled the steering lock to lock 100 times or more now and the whine does not stop. Do I need to put a vacuum on the system and try to purge it that way? There was no whine before but I just replaced the pump while I had room with everything out of the way and replaced the high pressure line because the fitting was leaking at the pump. This is very irritating because I thought replacing the pump would be beneficial.

So I am not sure exactly what is going on with my truck. It is a 2004 F250 has a 6.0 L. Sometimes when I take off from a stop the truck has no power and blows some black smoke. Then the turbo kicks in and all is fine. It comes and goes when it pleases no matter the temperature. What started happening is when I drive it a steady pace on the highway sometimes the turbo gets quieter and louder and quieter and louder sometimes when it gets quieter I see a little bit of black coming out of the tailpipe. Sometimes it doesn't do it at all. Also sometimes when I let off the gas the truck sounds like it's trying to laugh at me like a wastegate is fluttering.

I have a 4 inch MBRP turbo back straight pipe and I hear a lot of other 6.0 that sound much louder.
just curious as to why that may be?

So I took the wife to the pumpkin farm today, and was we were pulling into the grass/mud parking lot, my tires just started spinning. I stopped because I wasn't going anywhere and I turned my truck to go into 4x4(SOTF) and it made this LOUD clunk and then went into 4x4. Everything is ok and I tried it 4-5 after that to see if it would keep making that noise and it did not.

Have a 2004 f250 that is having issues. Once the truck is started the idle goes from normal to loud almost sounds like its going to stall. A few weeks back the same happened when i was on a red light. It choked almost to where it was going to die. I accelerated when light turned green and would not move at all. I had to literally use full throttle to get out the road at about 5 mph. I pulled in to a gas station and fueled up as i had a quarter of diesel left and it stopped the rough idle and power starvation once i started the truck up again. It sees like this time its getting more persistent... FML AND THESE 6.0 problems

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've got an 03 f250 superduty and a few weeks ago i was driving home pulled to the side of the road to get a phone call and my truck sounded like it was misfiring and started to shake very rough so i quickly got it home and it barely made it up hills with no power at all, took it to the mechanic and he said it was my wiring harness, so i replaced it and it took weeks to get here and i finally get it in and my truck still seems to be misfiring ad idling very rough, I replaced my oil less then 1000km ago and I've had 2 injectors replaced. I've talked to a few diesel mechs and he recommended to put some hot shots in it.
