Ford 6.0L Power Stroke Diesel :: Clack At Low Speed Acceleration?
Apr 20, 2016
What makes a 6.0 or 7.3 "clack"? I am not experienced enough with internals of a diesel to understand it.
Reason I ask, is my 6.0 is clackier than ANY other 6.0 or 7.3 that I have encountered. I mean it really cackles. Injector timing?
the engine was "bulletproofed" and (as the seller stated to me) was "flashed with a custom designed tune made by a Powerstroke specialist"... to which I have no further information on. This I assume was done for longevity and not performance.
Its quiet on the highway, but in town and stop-starts or low-speed acceleration it is crazy crackly.

I have noticed a small vibration at 40-50 mph for a few weeks now and was unsure to the issue.. ( I just checked wheel bearing ect , last night ) . This morning at a stop light she started to white smoke shake and clack, somewhat violently, when I pull away from a stop it seems to smooth out and run normally.. A stuck injector ? Toast injector ?

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.

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.

My 2007 6.0 has a really rough (almost 'miss') during cold start up. After 5 seconds or so, it smooths back out and sounds normal. Until gauge reaches normal operating temp - there is a surge/lack of power during light acceleration. I also hear a frequent compressor coming on and running for a while which I am contributing to a possible vacuum leak. Maintenance is always done on time and I've already had a few costly repairs (both internally as well as externally) on the engine. I usually always wait for the glow-plug indicator to turn off before cranking the engine and let it idle for 5-10 minutes prior to driving it. Once the vehicle climbs to normal temp. everything seems to be fine but the compressor still comes back on every so often.IS it worth simply replacing the vacuum canister located behind the passenger side battery - or should I find someone to hook up a diagnostic unit first?

I have an 03 Excursion with 220,000 on the clock. Started getting harder starts randomly about a month ago, maybe a little more, pulled codes got p2290. Reset everything, changed the oil, oil filter, both fuel filters, eventually the ICP sensor itself and rebuilt the IPR with new screen kit and rings. Hard start went away for about a week but ICP pressure was dropping drastically during hard throttle or even trying to go up a good sized hill. I had a bypass oil filtration kit on and noticed that the connection on top of the oil filter housing was weeping at idle and leaking enough at throttle to possibly cause an issue. Replaced with new OEM filter cap and fill cap, and ended up with a no start and low ICP pressure.
Got it started today after a long crank (15+ seconds), ICP and IPR at idle both warm and cold are mid 600's and low 20's (I can get actuals if needed). After reaching operating temp starts fine after shut off (both immediate and after sitting for 20 minutes). I picked up a selection of parts and tools including an ICP air test tool. Also grabbed a hpop gasket kit and the updated O-rings for the whole system. Live scanning wise I have an Edge CTS and also an SCT x4 that I can use.

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.....

Saturday while moving some items for the inlaws my truck, while moving at slow speed, reduced power to the point where it almost stalled, anti lock brakes were growling, right rear tire was dragging the brakes skidding the tire. maybe ten seconds then ran normal. got to stop sign and made a right turn and at about 30 mph started doing the same on and off for maybe 30 seconds. All the time Advance Track light blinking 3 times then pause, and repeating.
Stopped in a parking lot for a couple mins, did not shut off but drove the rest of the way home normally. At home we could smell brakes cooking, right rear brake disk was very hot. Drove to dealer Sunday morn with Advance Track over-ridden and ran normal. What would happen at highway speeds or towing my fiver? Bet they cant reproduce the prob, left no code etc. You know what that means.... I will update later.

First of all, I have 2004 f-350 92K miles with a stock 6.0 - EGR deletes and new oil cooler is the only updates.
Two weeks ago I had an issue pop up. When I tried to start from a dead stop there was no acceleration, it would idle ok but when i pressed on the peddle NOTHING! I called the local diesel guru, he recommended I change the fuel filters. After I did this there was a tremendous improvement in performance.
After a few days of normal driving, I noticed a subtle reduction in throttle response. Today I noticed a slight lag when accelerating which lasted about 3 miles until there is once again no acceleration. It will start normally and idle is a little rough, but will not accelerate even in park the engine is extremely slow to accelerate.

What is a "normal" number people see on their load factor? Mine was around 25-30 a few weeks ago but I noticed it is increasing to around 30-40 once I'm in gear, in park it's fine. My acceleration is also getting a bit sluggish too especially going up hills and my throttle isn't responding all the way, my turbo boost is normal though and I don't think there is any VGT stiction. I'm thinking either a fuel filter or a MAF sensor to start with. Fuel filters have been in exactly 10 months. Can a dirty fuel filter, air filter, or MAF sensor affect engine load at idle and how fast it accelerates? I feel like I'm pulling a trailer and with it being more sluggish, my transmission is shifting harder as well.

My ride again has started to develop a small studder during acceleration. It seems like only when it's cold. But when the temps are at normal it's not there.
At work now, but would like to get a heads up on it by the time I get home. To know what to look for.
No modes, no codes nothing but the studder.
Using T6 every 5000klm, fuel filter every 15000klm.
I have a fuel filter at home and will first replace it, before anything else.
BTW, all filter are OEM
About a year ago I had something similar. But I through some codes. I will look them up here at FTE.

I'm getting some light surging while under acceleration. None at idle or once in overdrive. I cleaned out by exhaust back pressure although it wasn't really that dirty. Thinking about replacing the sensor anyway but it is a little pricy to just buy for no reason. Should I look for anything else? And where I'd the best place to get one? I've seen the 20 amazon ones or over 100 at the parts store.

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 have a 2006 6.0l f350 crew cab that blows air hard every time I accelerate. Sounds like you're going 100mph with the hood unlatched. It blows real hard for a minute and goes away if I accelerate through it or let off.

Always regretted selling my 1988 ford diesel. It was a stick shift 4x regs cab. Very fun to drive. But I was a kid so when it developed a tranny noise I panicked and sold it. So, I bought a pile of crap in the form of a 2004 super dooty. It's a long bed ex cab, but had a stick shift!
It's got 330k on the clock, spicer rear end, and the famed 6.0. It's 4x4.. The truck isn't running and has a laundry list of engine issues including coolant blowing out under acceleration, hpop failing, weak injectors, oil leaks.
Compression is claimed to be good, but I'm thinking it would be easier and cheaper to fix up a used engine and swap it in. I'm open to other engines too, so I'd love to hear about options for that.
My research indicates that the 6.0 can be made to work well. For the money I have into the truck there is some room to invest in the engine. I have a line on a lo mile used 2006 6.0 engine. I've been told that the later years like 06 were less prone to some of the issues. Would this engine require head studs/gaskets and hpop fixes?
I'd be doing an egr delete for sure. And a coolant filter setup which is a new concept to me. What else would need to be done to bolster this engine? Turbos okay in these? I saw my friends ford burn to the ground from a cracked turbo. Or, should I put a gas engine in?

Shes a rocket at low speeds but at speeds above 50-60 acceleration is slow. How can you boost it? Bigger turbo? Better injectors? Rpms aren't maxed, it just seems sluggish...

I don't think it is the switch. About 3 months ago towing a heavy load I smoked my Trans during that time when the transmission got over 220 the dome lights would flash and the door ajar warning would flash. I just thought it was a high temp warning. Now tranny is fixed I was towing another heavy load and it started doing it again but all temps are good. I Unhitched load and now it does it most of the time when I accelerate. It seems to do it only under load on the engine. Called ford and they said it's not a warning and they think it's a electrical short. But it only does it if I accelerate.

Just noticed a sound of air sucking sound under the hood on heavy acceleration only, the harder I push the louder it gets. Either sucking or hissing sound. I feel no difference in driving. No loss of power or anything else. Just the sound of air coming out like a leaking air line. I will check later this afternoon if its affecting my turbo boost. I have 235000 klms on the clock

I was taking a trip the other day and needed to pass some slow traffic and found that the engine quit making power at around 95 mph. From 45 to 95 comes fast. Not good to have power stop when passing.
I know it is not safe to be driving our trucks at around 100 mph, but for a short burst to pass traffic, it is more dangerous to have the engine quit making power while you are trying to pass.
We purchased our truck new in 2012 so since I just found out about the problem, I have not had the truck up to 95 before now.

So my fan speed sensor popped up on Torque. I almost never hear the engine fan in the first place. But once in a while I do. I've only ever heard it when I'm laden with enough weight to really strain the engine. It sounds like a freight train when it does kick on. Should I be worried? I've done the EGR delete. New oil cooler. 4" straight pipe from turbo to just behind the cab. 130k on the works. 6spd manual.
