Ford 6.0L Power Stroke Diesel :: Rough Running / Truck Started Bucking And Hesitating At 45 MPH

Since our weather has returned to the cold side......my truck has started bucking and hesitating at 45 mph with EOT @ 130 and ECT @ 140. I can gas on it and it will clear up/let off and it would start up again once it gets below 50 mph. Once the deltas reach 150+ it clears up completely. Its never done this until this week. FICM volts are steady @ 48V. What is causing this or what to look for?

Ford 6.7L Power Stroke Diesel :: 2011 - Check Engine Light Came On And Truck Started Running Rough

Well it finally happened, a couple of weeks ago I was headed to an MX race and my check engine light came on and it started running rough. Long story short a piece of an exhaust valve broke off and went out through the head. Dealer has been great even though I was 300 miles from home and they did get me a rental(small POS SUV). Truck was supposed to be finished this week, but now they are saying the head gasket is on back order and they probably won't have one until the middle of April......... I can't be without my truck that long, but not much I can do. By the way truck is completely stock with just under 20K on it, and I have never had any issues with any of my Ford trucks or Ford diesels, even my old 6.0.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - SES Light Came On / Truck Started Running Rough And Lose Power

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

Ford 6.0L Power Stroke Diesel :: Rough Running Like Missing When Cold / Puffs Of Blue Smoke From Tail Pipe

My truck has been having this issue pretty much since I have had it, but it seems to be getting worse, or so I think.

When the truck is cold, it does not want to move very well. Like it's missing, and it does this until it gets warmer. Also, I have puffs of blue smoke come out the tailpipe when this occurs with it cold.

Injectors? Injector o-rings? Stiction?

FICM volts are good at 46.5v-48v when cranking.

Ford 6.0L Power Stroke Diesel :: Truck Got 4 New Injectors But Still Running Rough

My Excursion got 4 new injectors a couple weeks ago and when I got it back, it was running rough. My mechanic told me it was going to take about 100 miles for them to break in.

300 miles later and it is still running rough. So I opened the hood, took a look around and saw this wiring harness unplugged. Where it goes? Youtube video shows where the harness is [URL] ......

Also, my truck has been shaking violently at 50 miles per hour, unless I hit tow haul, then it is moved up to 60... I am assuming its connected some how to that wiring harness being disconnected.

Ford 6.0L Power Stroke Diesel :: Truck Running Rough When Cold

My truck was running rough when cold, I went to check the ficm voltage while wife was cranking and coolant shot right into the ficm and cooked the sumbitch. Stop laughing that stuff happens to me all the time. Anyhow, got a new ficm and truck wont start. Starter kicks out after a few revs. I ran my own solenoid wire to the starter and it cranks just fine. ficm at 48.5 koeo and cranking, icp 1100+, ipr from 14.8 to around 40%, ...

It takes a few seconds for the cam/crank to sync but it does. I changed the fuel filters and primed it, Got new batteries, and threw a crank sensor for s+g. With the key on and me cranking it using the solenoid wire, it almost starts. But from the key it will kick out after a few seconds. All fuses and relays are good. I hear the pcm also controls the starter, could that have cooked when the ficm went or would it blow a fuse? Diagnosing using a scangauge2 ....

Ford 6.0L Power Stroke Diesel :: Running Rough After Putting Fuel In Truck Now Won't Start

This has me puzzled to no end. After my son had put fuel in my truck it began to run rough, and had to be towed home, and now won't start. Now the first thing I thought was that he put regular gas in. But he was sure he had not ,and the receipt from the pump indicates diesel. It was hard starting before this happened.

1st Misfortune of having gas put in instead of diesel and did your vehicle run afterwards.
2nd Here are my readings from my scangage:

Sync Yes/1, Ficm main power 48.5 v, ICV .17 (2.01 when cranking). ICP 1572. IPR 50.7.

Checked upper fuel filter for bubbles, none.
Engine oil pressure comes up immediately on cranking.

Don't know what else to check, these readings look fine to me. Only the fuel is something I'm not 100% sure of. It does smell like diesel not gasoline.

Ford 6.0L Power Stroke Diesel :: Truck Starts / Running Rough Then Die - Fuel Draining Out Of Bowl

2004 F550 with a 6.0. I had to clean out my fuel tank, replace the HFCM and filter on top of the engine. When I start the truck it will run for 30 seconds or so, start running rough then die. I opened the cap on the fuel filter housing on top of the engine to make sure the fuel was getting there. I turned the key on and the fuel bowl quickly filled up.

After a short time however, the fuel drained out. To where I do not know. I don't think this is normal as every time I've changed the upper filter on a 6.0 it is always full of fuel. Why could this one be draining out and could that be the issue why the truck dies after starting and running for a short period of time. I changed the o-ring on the cap and the new HFCM was purchased from Ford.

Ford 6.0L Power Stroke Diesel :: 2005 F350 Running Rough - No Power To Move

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.

So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Missing Until Truck Warms Up

I have a 2006 F250 6.0L. Just had a used motor with 108k miles put in. Had the motor studded, fire ringed, new injectors, new glow plugs, new radiator fluid filter system installed, had egr delete done, ficm board replaced, fuel pump replaced, a few other small items replaced as well. The problem I'm having is the truck runs like it has a miss until it warms up.

After that, it runs fine. It takes about 10/15 miles of driving before it runs like it should. Letting it run in the driveway for 10/15 minutes to warm up doesn't make a difference. When the truck starts, it lopes at an idle for about 5 mins before turbo kicks in & starts whistling. When I start driving it shakes & feels like it has no power until it warms up. Then you'd never know anything was wrong. Put way too much $ into the truck so far and can't keep going.

Ford 6.0L Power Stroke Diesel :: 2006 F250 Misfire / Engine Started Missing Out And Vibrating Very Bad

I've got an issue with my truck, I was towing home my camper this weekend and my engine started missing out and vibrating very bad, then it overheated... pulled over and check codes, p0263, p0299, p0300, p0301. Oil all over engine, tons of blow by, definitely a dead miss on cylinder 1. Smokes bad out of exhaust, zero power, and blows cap off of oil filler when loose, tons of smoke and oil from ccv.

My question is, could it be in the valve train? Or is it going to lie in the piston/rings? Blown head gasket? It did overheat, but didn't puke out of bottle, turbo timer kept it running for a bit after I shut it down roadside, egts were definitely high. Also the egr is deleted, have a predator programmer with custom tune for she delete.

Ford 6.0L Power Stroke Diesel :: 2004 F350 Started Sputtering Like Missing / Black Smoke

My dad has a 04 f350 6.0 and on his way back from a trip he filled up and drove 60 miles and it started smoking white smoke, after he let it sit a while he added fuel injector cleaner thinking it might have been somewhat bad fuel. Drove it 20 more miles and it it changed to black smoke and started sputtering like it was missing. Blowing a lot of smoke. Took it to ford dealer and they checked for codes and it said the #8 injector was bad and needed replaced. My question is would the injector going bad cause all the smoke and missing?

Ford 6.0L Power Stroke Diesel :: 2004 - Missing And Rough Idle After Sitting All Day In Rain - Parked

Truck (04 excursion, 2WD, early build 6.0, 160k) started missing and rough idle on way home from work after sitting all day in rain - parked. started fine in morning and drove to work with no trouble - it was raining over night too.

To get you up to speed. for a few weeks before had intermittent trouble starting. would fire up as normal, fast and loud, but then stall immediately (usually after sitting overnight). would start back up but with a little long on the key and some gas pedal action. only happen one out of ten or twenty starts and seemed to follow getting fuel in unknown locations while on a trip out of town. decided to change out fuel filters and drain separator. seemed to fix it for a week or so then it happened again two days before above event, while weather was dry. Not sure if related but only recent problem to speak of.

Back to current:
- no check engine light or codes (I have a scanner)
- stalled out close enough to home the night in question I rolled it into driveway and tried to start it while rolling in neutral - no start
- once parked in driveway also no start
- next evening wanted to get it into garage (to dry off) and it started but rough idle and missing. this was after 24 more hours sitting in rain.
- been in garage 24 more hours and this evening got it to run but same result (rough idle and hard start). tried to check connections (mainly FICM) and move wire loom around - still same.......

Where to check next, need some diagnostic...

Ford 7.3L Power Stroke (1999-2003) :: Truck Running Rough And On Less Than 8 Cylinders

I had an HPOP line burst and soak the engine compartment with oil. I replaced the line and degreased the engine and rinsed it off. I started the truck and let it idle for 15 minutes or so before driving it. On the way home right after a shift it started chugging and running terribly. The check engine light was on as well. I limped it the mile or so home and shut it off. I restarted it and it runs just fine. I checked the DTC's with Forscan and there were a bunch of things that were mostly related to the HPOP and the MAT sensor that was shredded when the line blew. I left the hood open to dry out today and I'm hoping it is just some water in a connector. Does that sound plausible?
