Ford 6.0L Power Stroke Diesel :: 2005 Truck Buck / Miss Not Just Under Load
Truck has not been bullet proofed and has aftermarket air intake. Truck has 185km on it (purchased at 160km a year ago). For the Ham Radio guys out there, this is the most electrically noisy vehicle I've owned with S9+ noise while accelerating and S7 going down the highway ...
The faults show up as:edit Can be hard to start cold, takes couple of tries if it's been sitting for a bit (week or more)
No power when cold, that is a lot of pedal results in little power
Misses a lot when cold
Light blue smoke when missing when cold
When fully warmed up which takes 15 minutes of idling regardless the time of year:under load (heavy acceleration while loaded or not, or just in towing, or carrying) it misses a few times a minute, otherwise runs well
It feels like it just doesn't fire a cylinder if it were a gasser, or as if the spark plug weren't connected, but it's not a constant miss, it is intermittent. No load means hardly any misses. Load means lots of misses even running down the road. Should be pulling hard up a hill where it misses lots more.
What I've looked at :
FICM voltage 47.8 standing, 47.6 cranking and running.
FICM is aftermarket and there are no cold solder joints.
Added Archoil 9100 with no change
Wires to FICM are tight and connectors aren't cracked
edit Wires to Injectors are tight and connectors aren't cracked
Exhaust temps range between 500F and 800F during any of these events
Basic ODB reader shows no codes
I'm looking for a couple of things - I'm not much of a mechanic so this has to go to a shop for diagnosis and repairs. Before I run it someplace, what sort of diagnostic tools should that shop be equipped with to find out what's going on? Also, given what you know of the problem, am I likely to damage things if I continue towing activities?
Ford 6.0L Power Stroke Diesel :: Hesitation / Miss During Acceleration
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've had good running on the truck but lately in the cold the idle has a weird skip to it like it's missing on a cyl. It will start fine, and run fine for about 30 seconds. Then it will start to mis. When giving pedal it goes away and it's driveable but it doesn't sound right. After a bit of running it's fine for the duration while warm. My monitors are I think all good, 48.5v, icp about 1250 psi. Is this the famed "injector stiction"?

2005 6.0l - codes are P0261 Cylinder 1 injector circuit low. PO263 Cylinder 1 Contribution/balance and PO270 cylinder 4 circuit low. Ficm still reads 48 plus or minus .5. What is really puzzling is how changing the oil cooler and the EGR cooler would create these problems. Did I screw up the injector harness. Vehicle does not smoke either white or black. Low idle miss and at 55 it chugs once up to speed. Don't want to go Ford if I can avoid them. Whats going on.

View 4 RepliesFord 6.0L Power Stroke Diesel :: 2004 F350 - Low Idle RPM And Stall
Ok a little background on this truck. it is a 04 F350 6.0. Early build, with the ipr under the turbo an the earlier hpop. A few years ago the oil cooler blew on me and I got it rebuilt with a full bullet proof diesel kit and high flow egr cooler. Last year my turbo went out and I had it rebuilt and added a 5" MBRP turbo back exhaust. there have been multiple other parts updated and replaced but those are the major ones.
A few weeks ago I began loosing my oil pressure at idle. It was hard starting as well. I though that was from the cold winter here but it apparently wasn't. Before I had a chance to check the truck out, it lost all power on my way to work and staled out on me.
I just finished tearing into the high pressure oil pump. Found the ball plug was gone from the side. Tapped and plugged it. When I started it up it seemed to be idling fine. After it warmed up a bit i gave it some throttle and it would not go over 1000 rpm and spit out black smoke. Once the engine temp came up the idle speed dropped to around 300 rpm and eventually stalled. My oil pressure never dropped and the check engine light never came on. With the engine up to temp it will turn over and fire but as soon as I let go of the key it dies.
I do not currently have anything to get readings other than whats on the cluster. Do i have any options that wont cost me a ton to get my readings?
Ford 6.0L Power Stroke Diesel :: 2004 - Stumble And Hesitates At Idle / Acceleration?
I have a 2004 f350 6.0 it has 73000 miles on it. I've had the truck for about a month and its developed a slight stumble, hesitation. It does it during idle and acceleration, if I give it more throttle it smooths out. The cel is not on and there are no stored codes.It did this a few days after i bought it,i noticed the map sensor was broke in half so i replaced that and it smoothed out.But it came back. Exhaust is clean no white or black smoke at all.
View 11 RepliesFord 6.0L Power Stroke Diesel :: Truck Will Sometimes Momentarily Cut Out And Buck A Couple Of Times
I replaced the speed sensor in the differential yesterday, but it didn't make a lick of difference. I've been having intermittent problems with the speedo ever since I bought the truck. When the speedo starts acting up, the truck will sometimes momentarily cut out and buck a couple of times. It was first mentioned this post, post # 35. I had the truck in the shop for a new oil cooler, EGR delete, standpipes, dummy plugs and STC fittings, and when I got it back it ran worse than before as detailed here in post #1. It turned out I had a torn IPR screen.
I replaced that and it cleared up all of the problems I had except for the speedo problem I originally had. The truck actually ran perfectly on the way home from work yesterday, about 20 miles. No speedo problems and no cutting out. This is not unusual, as the problem is only intermittent. I put the new VSS in last night but did not drive it until this morning. This morning, same thing again, speedo swinging crazily. When cruising about 70 it the speedo would suddenly jump up to about 90 and that is when the truck would cut out and buck a couple of time. The VSS is a Dorman product and proudly displays "MADE IN CHINA".
Should I try a better quality sensor? Rock Auto sells an Airtex/Wells sensor that seems to be of good quality, but I can't determine where it was manufactured. The only reason I bought the Dorman is because I could get it next day from Amazon. Should I be looking at another source for the problem? This is very discouraging because this one thing is what is keeping the truck from being mechanically sound, and I'm trying to get it ready to tow an RV this summer.
Ford 6.0L Power Stroke Diesel :: Stuttering On Acceleration / Fuel PSI At Idle Barely Move
I fear my truck may be stuttering on acceleration.
I hooked up a fuel pressure gauge tonight and the fuel PSI at idle and under acceleration... barely moved. Stayed between 60-62PSI.
I'm thinking this isn't normal... shouldn't the PSI be reduced especially when I accelerate hard ?
I'm thinking the "delivery" fuel line... perhaps there is a bottle neck somewhere which is causing constant PSI at the fuel housing ?
Ford 6.0L Power Stroke Diesel :: Sudden Buck / Surge Accompanied With Black Smoke
So my buddy was driving my truck and boat through Amarillo and suddeny had a buck/surge accompanied with black smoke. I left my torque app with him. Its throwing codes: P2287,2285, and P????(fault log got erased and I'm going from memory) concerning #8 cyl. I got there today and we noticed coolant leak on left side. Its small and I cant tell the source, but it is wetting the exhaust manifold on left side. Also now its blowing white, black, grey smoke. At idle its more white/ grey. Under load it mixes a little blck in. I only had time to check the ICP on torque and at idle its bouncing from 0.9 to 1.1. Unplugged ICP ran about the same. Still started and idled fine with white smoke. No oil in ICP or connector.
So I'm no expert but I think ive got a bad icp and something else going on. I didn't pull the egr valve and look so no idea on the cooler ,yup syill have the cooler. Degas has a small amount of white residue directly under the cap but no puking. Degas is just below the max line (on the sticker).
One other note only code originally was the 2287 last night. Now this am there was the other codes ref'd above.

Still chasing a surge for some time while cold, mainly. While hot and cruising 65 mph the turbo still surges faintly.. but today was a different story, very fast and high surging from the turbo only, while on overdrive as usual. It calmed down as i dropped the boost a bit but it was quick swings of about 3-5 psi which is quite bad for what it had been doing which was manageable.
Short of taking off the turbo, I took out the VGT solenoid and it had some oil burnt on the end, cleaned that up and pushed the plunger in all the way a few times and it 'seemed' to have worked greatly, until today.
I pulled some other numbers;
KOEO
Map 13.7
EBP 14.1
Baro 28.2
Cold Idle
Map 14.0
EBP 16.5
Baro 28.2
When cold, mainly below 130F the RPM gauge itself will surge or hesitate around 1700-2000 RPM. Any higher or lower it will be smoother I suppose....
Ford 6.0L Power Stroke Diesel :: 2005 - Smoking White Or Gray At Idle But Blowing Black Smoke On Acceleration
Well my problem went from bad to worse. My 05 started running rough at idle, then smoothed out a bit but started smoking on acceleration a little. At this point it felt like it had more power than ever before and even ran smoother running up to 3k RPM before shifting (manual transmission). But now it's smoking so bad, I can't really drive it. It's smoking white or gray at idle but blowing black smoke on acceleration. I had a cylinder 5 contribution code but with the amount of smoke it's hard to believe only one injector is a problem. I pulled the EGR valve and it doesn't look stuck open but I'm going to replace it anyway.

i am recently a new owner of a 2006 6.0 F-350. So like any other used rig, it has its quirks. So the one that is bugging me to s the steering. It has been surging hard while driving. It mostly does this when cold. It feels like it's bouncing back and forth then I have to stop and force it from lock to lock. Once I do this it seems to stop it till the next day. I checked the PS reservoir and it's full. The power steering pump looks like it has a slight leak but doesn't seem to be a major issue. The lines going into the steer box are clean and no leaks...

After start up it bucks and surges, acts like it is starving. RPMs fluctuate. Once it fully warms up and driven a little bit it clears and runs normal. This all began after the alternator went bad and battery warning light came on. Batteries never went completely dead, but could low batteries effect sensors or control module. This morning it was difficult to start, not low battery problem, but a lot of bucking and black smoke. I changed the fuel filters and a little better. New air filter last week when alternator was replaced. No codes have appeared.

So I changed my oil with T6 and archoil and immediate miss at around 1500rpm then it clears up. I can stomp on it after that and it's fine. I know this has happened to others. My last oil change was also T6 and archoil. 2005 F250, stock, atlas 40, 216,000 miles.
View 5 RepliesFord 6.0L Power Stroke Diesel :: 2003 F450 Surges And Jumps / Code P0528 Coming Up
I own a 2003 Ford F-450 Superduty Chassis w/Utility Body. Owned it for the last 2-1/2 years . So far, the only things needing replacement were an Alternator, FICM, and routine oil and transmission fluid as well as filters.
This past week the truck started lurching while in traffic. I brought it back to the shop and put the scanner on it, and found codes for #1,#3,#5 injectors imbalance and no circuit to the fan motor. Did some research and found low oil and/or dirty oil could affect the injectors, I changed the oil and all filters also removed the EGR and cleaned it too.
I started the truck ran it, stopped, and restarted and let it run for a few. I cleared the codes and did another test. The only code that came up was the Cooling fan P0528 again. I let the truck run. All of a sudden the truck revved up and I could hear the turbo kick in and the engine seemed to take a life of it's own. I did another round with the scanned and found codes for Cruise Control popping up P0565 through p0569 and the p0528 again along with a p1000.
My truck is not equipped with cruise control, but apparently that is what might be making the engine surge. What do I do? What this might be???
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Occasional Miss At Highway Speeds / Bucking And Jerking During Even Gentle Acceleration
165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.
Ford 7.3L Power Stroke (1999-2003) :: Truck Has A Rough Idle And Sounds Like There Is A Miss
I just installed glow plugs, ucvh, stage 2 rosewood injectors, t500, ipr and gear head tunes. I have out 97 miles on the truck since all this was installed and the truck seems to run okay but has a rough idle and sounds like there is a mis? What should I look into first?
