Ford Super Duty (1999-2016) :: 2003 F250 - Intermittent Power Loss / Bogs Down To 40 Mph Then Starts Missing
My truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.
Ford Super Duty (1999-2016) :: 2008 - Loss Of Power And Sputters Going Uphill
I bought 08 6.4 113000 on it 4x4 lariet drove 300 miles home. No problem 2 days later runs fine for 45 minutes than loses power and sputters up hills starts no problem every morning every time wait awhile sometimes runs fine was on e when test drove canged both fuel filters oil and drained 8 quarts tranny fluid and replaced it. When problematic rpms wont go over 2 turbo psi seems high seems in sync with rpms dropped...

I just bought this truck for a pretty good price it has 225000 on it the engine was over heating. The guy put new rad, new water pump, new fan clutch, and a new heater core with thermostat. The truck still over heated so I pulled the thermostat to see what happens and the truck over heats even faster. All this happens while driving regardless of ac on or off. I got a motor and put a motor in it with all new pump and thermostat. I put new coolant in and flush radiator. I cut a hole in the cat to see if the cat was plugged for the truck seems to have low power and sputters. With in 1mile the truck over heated dumping all the coolant out of the system which the truck did as well before. Will the diesel rad work in this truck I have a diesel one I can put in since its a bigger rad?

One of my work trucks is a 99 F-250 5.4L. Up until recently it's been running strong. Then one day it's like someone flipped a switch, and now it runs like it's losing power.
Symptoms: a quick short stumble when you first hit the accelerator. While driving, it takes the entire pedal to accelerate. Even with the pedal to the floor, it won't keep up with traffic. Driving uphill, it will barely maintain 40 mph.
I've checked everything I can think of. Fluids and filters are all good. Battery and alternator are good. There are no trouble codes. I have Autoenginuity with the Ford Bundle, and the truck passes every diagnostic test I throw at it.
There's no smoke. It still idles pretty smooth, although there is a slight and very quick random shudder in the idle that has started at the same time it started losing power.
Transmission is good. The last thing I tried was to change the fuel filter, but that made zero difference. Quick question, does the tank on the 5.4L trucks have a pickup screen like the diesels? If so, I might try blowing some compressed air through the fuel line and see if it dislodges anything.
So that's where I'm at. It has no power, yet I can't find a single thing wrong with it.
Ford Super Duty (1999-2016) :: F250 - Big Power Loss Momentarily
I have a 99 F-250SD with 5.4 automatic that just all of a sudden started running unevenly at random times, but frequently. There is a pending code P0300 Random/multiple cylinder misfire. I have had the truck for 12 years and it has run perfectly for the last 10+ years and just started this problem, it did not come on slowly but all of a sudden. I have seen on here that some people say that 90% of the time a PO300 is a bad cop. I replaced the plugs 60k miles ago when I had a bad coil on plug 10 years ago that did not set any codes, but this seems very different that more than one cylinder seems affected, like maybe 2 or more cylinders are not firing momentarily.
There is a big power loss momentarily while it happens, but doesn't happen for long. The fuel pressure stays pretty constant (30 psi at rail) even while it happens, and it can affect the idle as well as while accelerating or cruising at speed. I cant imagine more than one coil on plug would be skipping at the same times or fail at the exact same time, but maybe having only one bad cop could cause this much hesitation? Does the code that indicates random/multiple cylinder misfire rule out only one bad cop? It just seems like running on 7 cylinders wouldn't be so noticeable. Could a sticking egr valve cause unevenness at idle and higher rpms and set a P0300 code? Would checking manifold vacuum be they way to see if egr valve is not working correctly.
Ford Super Duty (1999-2016) :: 2008 F250 - Sudden Loss Of Power
On the highway doing 100 mph. during af take over, my Ford F-250 6,4 Super Duty 2008, lost nearly all power. (now it is like driving my old hummer h1)
Engine and car runs/starts great, only 10 minutes uptil 60 mph. now.
My mechanic has given up. He checked following:
EGR = OK
HOSES = OK
ERROR CODES = NONE
INTER COOLER = OK
PARTICLE FILTER CLEAN = OK
TEST WITHOUT EXHAUST = NO DIFFERENCE
FLUIDS = OK
Hopefully something I can fix with my hammer. The car has 85.000 miles on the clock.
Ford Super Duty (1999-2016) :: 2004 F250 - Loss Of Power Door Locks And Power Windows
I have a 2004 F250 Super duty that had a battery die (I left the keys in the ignition switched on overnight) and after jumping the battery off the vehicle started up but now I have no power door lock or window functions. Any reason a dead battery issue might affect the power locks and windows?
View 10 RepliesFord Super Duty (1999-2016) :: 2000 F250 2wd V10 - Loss Of Passing Gear Power
When passing or going up small inclines on freeway, my F250 seems to make the shift to the passing gear but then almost a complete loss of power. Jerks around for a few seconds and finally provides enough power to at least get back to the original speed. (It feels kind of like the lurching, etc. I used to get when those stinking GM diesel injectors would act up in the 1990's.)
It also stays in first/second as I punch it while entering the freeway and doesn't want to make the shift. I can put it in neutral and race the engine, so I don't think it is an engine problem, unless the transmission is electronically controlled. I have a lot of computer dashboard gauge resets after falling to zero and sometimes have to set and release the parking brake to get the auto door locks and windows to work. (That started after a car break in where the door electronics were apparently pinched, but that was a couple of years ago.)
Does it sound like the transmission or electronics? In the old days replacing an automatic transmission filter seemed to fix a lot of transmission issues. Not an option now, but would I expect to see any results doing a transmission flush and fluid change? It's probably been about 60000 since I had that done. (157000 now).
Ford Super Duty (1999-2016) :: 2001 F250 V10 - Sudden Power Loss And Dies Randomly
I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.
Ford Super Duty (1999-2016) :: 2003 F250 - Harsh Shifting / Sluggish / Loss Of Power
I have a question for everyone out there with any insight of the harsh shifting with these trucks. I have a 2003 f250 super duty with the 5.4l and 126,000 miles on it. The problem I'm having is some weird shifting that has been going on over the last six months and I feel like I am just throwing money at this problem. My truck shifts hard from 2nd to 3rd and from 3rd to 4th with the most violent shifts being from 3rd to 4th! Between shifts is where it Is sluggish I mean if I am not on the throttle from those shift points I switch from driving a truck to a geo metro it is night and day with the felling of loss of power!
I have had it scanned at my local ford dealership and had a full diagnostics done and all I got was "it's since truck and a nice bill to come with it" they couldn't find a thing. So far I have all new motorcraft plugs, cops, changed fuel filter, had my catalytic converter checked if it was clogged,run on two different power balance tests! Still nothing! So now I'm lost I have heard things about these trannys and the lock up but I was told this only had to do with overdrive and it wouldn't happen at other gear changes. I still drive it everyday I have just figured out ways to calm it down if I stay off the gas when it's about to shift for a couple seconds then get back on the gas it is like it never happened.
Ford Super Duty (1999-2016) :: 2010 F250 V10 - Sudden Loss Of MPG
My 2010 F250 V10 120000 mile has a sudden loss of MPG. It usually is around 12 MPG but now I'm at 8 I checked the air filter and its clean I checked the tire pressure and there all up to pressure. I'm probably going to try the fuel filter next.

I was driving my 1999 F250 5.4 Triton last week, after noticing a thump while backing my small boat down the ramp (sounded like u joint) I went and parked. When I got back in the truck it starts fine but when I shift into reverse, it's staying in drive, anywhere I put my shift lever..... It's in drive! I even noticed that even all the way up into park it feels like it's in drive, but with something holding it back. If I give it gas while in park it will go forward! I have tightened the two torx screws under dash, pulled cable off and tried shifting by hand (clicks like switching gears, but still in drive) pulled pan, everything looked good there, fluid is nice and red, smells good, no metal in pan? It's the 4r100od tranny.
View 7 RepliesFord Super Duty (1999-2016) :: F250 - Airbag Light On - Loss Of Cruise Control
I have an early 1999 f250 diesel. I originally googled having the airbag light on and loss of cruise control and came up with it more than likely being a bad clock spring. So I replaced the clock spring, and it was definitely blown. I have a horn now, not sure if I did before or not, but still the light is on and no cruise control. The airbag light is flashing code 27 which I believe means the passenger airbag has issues.
So I tried turning the key in the switch for the passenger airbag to deactivate it, but it only lets me turn it 45 degrees and no light comes on. It looks like the key should turn 90 degrees but maybe I'm just an idiot. I see a lot of people with the bulbs dying and running into issues but that wouldn't explain the inability to turn the key 90 degrees. Also would the airbag light being on deactivate the cruise or is that just some other issue? For what its worth, I plugged in a code reader and no codes came up, just the flashing airbag light.
Ford Super Duty (1999-2016) :: 2006 F250 - Intermittent Loud Chirping Noise
I have a 2006 f250 lariat 192k no mods except k&n filter everything is stock. I have 2" pro comp level kit and a scan gauge 2 nothing fancy! Well the other day I noticed my truck was chirping like a Chirp chirp chirp...... Chirp chirp...... Chirp chirp chirp! It goes up and down with the rpm's but it's comes on and off only when the engine is up to running temps the belt does squeak during warm up but I don't think that's it, it's coming from the back of the engine I'm sure of it because I used a paper towel tube and listed right in the turbo hpop area on top of the engine but it's too hard to tell I can't find exactly where it's coming from, some people I've had listen think it's a belt or pulley or tensioner! But I'm not sure if it is because I've sprayed water, and wd40 on the belt and pulleys with no change!!! I'm afraid it's a lifter or something inside the engine yet it's too loud and pronounced to sound like it's coming from the inside! I'm just lost!

For about 6 months the cruise control on our '09 F-250 has been intermittently failing. One time I'll set it and it will work fine, the next time I try to set it and it fails. No particular rhyme or reason to when it fails to set.
Some of the tests that I did indicated it was the brake light switch on the brake pedal arm. It seemed to work perfectly a few times that I drove it after the installation but now it's back to working when it wants to.
I had a problem with the cruise on our '06 Ranger and it turned out to be the module. It acted a bit the same way in that it would set sometimes, other time not. I don't know if the two systems are similar or not.
Ford Super Duty (1999-2016) :: F250 4x4 V10 - Intermittent No Start / Complete Stall While Driving
1999 F250 SD Ex 4x4 V10 has been intermittently not starting, both cold and warm, began last fall but only happened once a month or so or longer. Would then start after trying again either right away or after waiting a bit. Now it is doing it on a regular basis. Sometimes it will start right away, sometimes won't but if you keep trying or wait awhile it starts, sometimes using the extra key will start it right away after the first one didn't, sometimes neither one. It does not try to turn over, make any noises, no warning lights flashing, just won't start.
Now also on two occasions within the past week, it just stopped while driving. Radio, dash lights, etc., stayed on. I got it to the side of the road with the little power steering left where it started up again right away.
No codes showed up. First mechanic couldn't find anything obvious or replicate problem. Changed air and fuel filters (fuel filter really needed changed), plugs. Got truck back and it wouldn't start next morning. He checked it again and got a code related to ignition, tried the spare key and it started up. Truck back home, next day same problem.
Mechanic 2 checked, no codes, kept several days but, of course, couldn't replicate problem. I'm not even sure what all they checked, used to be an excellent repair place but now they seem to only really on diagnostics and throw up their hands, very disappointing. Replaced solenoid and starter last year myself. Otherwise, have had no problems until this.
Ford Super Duty (1999-2016) :: 2001 F250 - Tachometer Intermittent / Jumps Up And Down Some Of The Time
The tach in my 01 F250 PSD has become intermittent. It works properly some of the time, not at all some of the time, and jumps up and down some of the time.
Does it get it's signal from the CPS? It has a blue CPS that's about a year old and the truck runs fine?
Ford Super Duty (1999-2016) :: 2002 F250 - Intermittent Noise Coming From Front End
I have a 2002 F-250 7.3. I was driving home from work on Tuesday (highway), I heard an intermittent noise coming from the front end, sounded like a rubbing/grinding noise. Yesterday on my way to wok, same thing, on and off. Yesterday on my way home the noise was constant, didn't go away. The noise comes at about 45mph and stays until I'm back under about 45mph, so mainly just on the highway. I put the truck in neutral and let off the pedal and the noise is still there which tells me it isn't engine related.
Yesterday after work I jacked up the front end, spun the tires, no noise. No play in the tires top/bottom or side/side. Took the tires off and what I did notice is the right axle u-joint is shot. I am hearing the noise in 2wd so I don't know if its the u-joint that's making the noise. Could it be a bad wheel hub bearing? Is it the u-joint? Maybe needle bearing??
Ford Super Duty (1999-2016) :: 2014 F250 - Intermittent Check Engine Light
My 2014 F-250 is having a repeat problem with an intermittent cell engine light. About 10000 miles ago it happened, and they changed out the egr cooler. Saying it was gummed up with soot. Problem just started up again. Light will stay on for about 3 or 4 restarts then sir off on its own. It's this a known issue with the 6.7? Is there a way to prevent it?
