Ford 6.0L Power Stroke Diesel :: Injector Stiction Not Working Properly?
Cold start the injectors definitely are not "clicking" the way they should be. Bought a scan gauge II and checked the FICM voltage and it never drops below 48V. EOT/ECT never really get past 8/9* ....
Issue is when I first start driving you can feel a definite miss, but as soon as the truck warms up it runs excellent, no issues starting hot. I did put 15w40 in it but upon some research I drained it and put in 5w40 syn and it definitely solved some of the issue but it's still there.
One other note the battery's are a little weak in the truck so tomorrow I will have new ones-putting this in as a side note in case it may cause an issue
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Tachometer Not Working Properly
I have an 06 f250 6.0. When I bought it a few weeks ago I turn the key on and let the glow plugs warm up and start the truck it would start easily. Now it seems like it's taking longer to start . The temperature are between 50 and 80 degrees. I changed the fuel filters and it's still taking to long to start.
2nd I noticed today that when my truck is at idle the Tachometer is at 0 and when I'm driving 60-70 MPh it goes up to 900 or maybe 1200. It seems to be running fine no loss of power that I can tell. What could be causing the long crank time and my Tachometer problems.
the glow plugs and injectors are new I don't remember the brand and the fuel filters are brand new Motorcraft.
Ford 6.0L Power Stroke Diesel :: 2004 F350 - Intermittent Loss Of Power / Stall Or Stumble When Engine Is Cold
I just bought a 2004 F350 6.0 cclb 6 speed with 260k on it. The previous owner seemed to have taken good care of the truck. It is basically stock with the exception of the blue spring mod, and a sinister diesel coolant filter. Anyways, I brought the truck home and it ran great. Now I have an issue that needs to be addressed.
The issue: I am experiencing a intermittent loss of power, stall, or stumble when engine is cold. After sitting all night the truck will start fine and idle fine. But when I try to accelerate and bring engine RPM up the engine will stumble and lose all throttle response, when this happens the WTS and WIF light flash. Sometimes it just stumbles, sometimes the truck will actually die and then restart. The issue seems to go away after the engine has reached operating temp.
I did some research on the issue and it seems there is actually a TSB out from ford for this issue. It explains that some 2003-2004 6.0's might have wiring harness chaffing issues. This is what the issue I am having seems like to me (shorting harness). I looked up codes on the truck and there is an active code (#8 glow plug circuit fault). I did a short visual inspection of harness and didn't see anything out of the ordinary. But i wonder if it would be worth changing both sides of the glow plug harness?
Ford 6.0L Power Stroke Diesel :: 2005 F350 - Climate Control Not Working Properly
I have a 2005 6.0 f350 lariat... My climate control doesn't switch very well I can get it to go to floor sometimes after 15min of pressing the button. The vacuum pump is good the tank has no cracks. I feel that the system is either plugged up or has a leak. I cleaned the tank after my hub seals went and it sucked a ton of dust and dirt through my wheel bearings in to the tank. Is the vacuum switching part of the digital display? Or is there a separate part?

When I take off from a start it will intermittently stumble or hesitate, seems to be around 1500 rpm. have also noted it at higher speed while cruising. its more like a momentary power cut than a miss fire.
So far I have done the following
new fuel filters
clean MAF
new PCV valve
new spark plugs
check all hoses and plugs etc
injector clean
checked techstream for codes. there is one for a heated O2 sensor but dont think thats it.

Ford 7.3L Power Stroke (1999-2003) :: Intermittent Engine Light / Momentary Surge At Highway Speeds
I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?
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.

I have a 2006 F-250 4x4 with no cat, and no egr but the valve is still connected. It has about 146,000 miles. Just recently when warm, it has a slight miss every once and a while when stopped and in gear. Just a slight drop in RPM then recovery. Its mainly used on the highway and 99% of the time I set the cruise and its smooth as silk. Every once and a while I feel it stumble once or twice, recover and it is fine for the next 80 miles with no issue. It started as once every few trips but now It seems to be happening at least once every other. I use Motorcraft filters (maybe 6K on the fuel filters) and rotella oil. My scangaugeII shows no codes and no Injector pressure issue (1200-1400 at 75 mph depending on grade) and the FICM voltage stays between 48.5v and 49.0V. What should I check?
View 2 RepliesFord 6.0L Power Stroke Diesel :: Overdrive Stumble / Truck Barely Idling When Come To A Stop
So from what I have gathered online, it is an injector(s) issue. I've only had it happen to me twice at that speed but when I came to a stop afterward, my truck was barely idling.
I'm not sure if my sct programmer is able to show injector codes but it will show gp codes. I guess my question is are failing injectors that intermittent typically? Also, much luck with Rev X clearing that issue up?
Ford 6.0L Power Stroke Diesel :: 2006 - Stumble Always Worst On Final Drive Gear
First... Items I have replaced:
- New EGR valve
- New sensor
- New Fuel filters
- New Oil filter
Problem:
While driving I have a stumble along with a small amount of black smoke at this time ( was white/bluish smoke ) previous. I have dis-connected the batteries to force the computer to relearn the EGR valve. The turbo spools up .. getting about 20 psi @ hard throttle and then about 5 psi after it goes into the final drive gear. Speaking of which ... the stumble is always worst on the final drive gear...
Ford 6.0L Power Stroke Diesel :: No Boost - Won't Shift Properly?
Ok so I just put an egr delete and a new oil cooler in the truck. Everything went pretty well but when I was going for a test drive I'm not building any boost. I can here the turbo whistle like always but there no power and none of my gauges register boost. Also, the transmission is shifting funny I don't know how else to explain it but just not right. Now I don't see/smell any exhaust leaks and can't hear anything too wierd in that department. I checked the intake and the intercooler tubes I think their called and all good there. However, I did break my map sensor post off my intake during the install . So my map tube was just open to the atmosphere I didn't plug it or anything. Could that be the cause of my woes? Is there any thing I can do to alleviate the issues I'm having with the map? Can I just plug it until I fix it? And is there anything else to check on my turbo?

In my 2011 F-250, 6.7, auto....it seems that at certain times went the tranny shifts from 2nd to 3rd and I pause with acceleration, for some reason the tranny seems to go into a slip mode and then slams into 3rd. Now I read about 8 months ago that there was a computer upgrade via Ford. Which they did when I was having some work done on the truck at the dealership.
View 14 RepliesFord 6.0L Power Stroke Diesel :: 2004 - Turbo Not Boosting Properly
I have an '04 6.0 and it doesn something strange. When for example I am going up a decent grade hill and passing, if I have to let off the throttle and then re apply, the turbo won't build boost, it sits at a couple pounds for a few seconds. Then after a few seconds it will build boost quickly again and work generally as normal. If it doesn't respond and I really need to get it to build boost NOW, if I push the accelerator to the floor, the delay shortens and it will often kick down a gear and then build boost. So if I gently accelerate, very slow to recover, if I hammer it, much quicker but regardless, when it's happening it's almost always the same situation, fully warmed up truck, warm/cold/freezing day and it happens when I back off and re apply. Thinking maybe a worn unison ring but not sure..

I have an 02 F350 7.3 ... I just installed my glowshift tripple gauge pillar set. I have an EGT, Boost and fuel pressure gauge ... I followed all the constructions on installing them. The boost is working just fine and the EGT was too, but after a while the needle started going back and forth and the red warning light what blinking and then it just sat at 0 with the warning light on and stay that way. My fuel pressure gauge is connected to a sensore i put in my fuel filter housing, my fuel pressure gayge right from the start stayed at 30 psi with the red warning light on and just stays there .... Also the buttons to change the color and set the peak on the EGT gauge are sticking for some reason and staying down and aren't letting me change the color ...

I recently bought a 2005 F250 4x4 automatic trans with 177,000 miles. In the last 300 or so miles it has developed a whine from under the truck like gears not meshing. It is constant and only the speed of the truck seems to affect the volume of it. It is loudest, considerable louder, on deceleration. Different gears have no effect, 4x4 high or low has no effect, even slipping it into neutral while its rolling has no effect. I have seen various websites about bad wheel bearings, transfer cases, and rear end gears causing this type of noise. There is no vibrations, slipping, shuttering, at anything else unusual. Except for noise it drives ad rides completely normal.

View 7 RepliesFord 6.0L Power Stroke Diesel :: 2005 F250 - No Speedometer And ABS Light Is On
I have a 2005 F250 6.0l. I have no speedo and the ABS light is on. It was intermittent at first. It would go on and off if I hit a bump or braked quickly, but now for the last month the light has been on constantly.
I have tried the following to no avail:
1. check the harness to the VSS (rear ABS senor on the pumpkin)
2. replaced the VSS on the rear
3. check the lines from the vss for resistance and open short (and short to ground)
4. checked the HS-can network (pins 14 and 6 in the DLC to the respective HS-can + and - on the module) both have less than 5 ohms (about 3 ohms found) and no short.
5. checked the resistance of the network itself across pin 4-16 and found 60 ohms.
6. ran scans with OBD fusion for ABS (no abs found)
7. ran scans with forscan with laptop, does not detect ABS unit neither new or old module. note the TBC and IC both throw codes about not detecting the ABS.
8. check HS-can on the PCM as well as VSS wire from abs to pcm, no shorts or resistance.
9. check the number 11 fuse, (good) checked ALL fuses, only bad fuse found was trailer light number 20 engine bay. issue was a wire at the tailer connector was t-taped and not sealed leading to a short to frame.
10. checked the connector to the ABS module for power on both constant power pins, for open ground on both grounds, and power on run, all with in spec.
I've been diagnosing this for the last week, I am running out of things I can think of to check.
Ford 6.0L Power Stroke Diesel :: Engine Working Hard - Head Unseat - Where Does The Coolant Go
When the engine is working hard and the head (s) unseat, where does the coolant go, in the oil, to the atmosphere or both?
There are times when I am pulling heavy ( 18 to 20K+) pulling up a hill from a stop, and I can hear the engine working hard, then I later check the coolant level and it has drop.
Where did it go?
