Ford Super Duty (1999-2016) :: F250 V10 - Bogs Down On Hills And Passing Gear
When I "step on it" on the freeway or even a moderately inclined freeway ramp, it bogs down and actually takes a few moments to cover. Sometimes will leave me crawling at about 20mph for a few minutes. Engine revs just fine in neutral. If I very slowly build up speed I can cruise at 75mph, but forget passing. Also, this came along at the same time a severe shaking/shuddering spell started. Not always, but often it is shaking the entire body and certainly through the steering wheel. Was so bad the first time I stopped to see if I had a flat. Usually lasts until I slow way down and ease my speed back up. Had the front end steering structure replaced about two years ago, so I don't think it is that. What is the cause of the bog down and could the shaking be related? This truck sits for 2-3 weeks at a time and then I drive for about 50 miles and park it again. Can Michigan gasoline go bad that quickly?

2000 6.8 v10 F250 supper duty crew cab. 4x4 high switch's on (manual lock hubs installed) but 4x4 low will not engage. Brake input/out put tested good. Trans switch Park/"N" both test good. PCM reads switch output in all modes, (dash 4x4 selector). The only other issue I am having is the Vacuum is bad ( defrost default no blend door operation). Would vacuum loss prevent 4x4 lo range engagement (with manual hubs ) or should I go to the solenoid, relays on the case/ right fender?

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.

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?

I have a 1999 f250 super duty with the 5.4 Triton motor with a 5 speed. I bought the truck a couple months ago, and it had a bad manifold leak (not surprised lol). but it ran fine just noisy. So i had a shop do new gaskets and bolts. Then my problems started.........
When you start up the truck she runs fine and some times drives fine. I will be driving along and its like some one hits a switch and i suddenly loose all power it spits and sputters and i have to down shift to make any kind of hill.
So I figures I had a misfire i got a light on for cylinder 5. So I decided to change all coils and plugs hoping that would clear things up...... well it didn't. It ran great for roughly 15 miles then it started to do the same thing again. I've changed air filter and fuel filter also.
When it starts sputtering i sometimes get a check engine light on and then it goes away. when the light is on the codes are:
P1151 A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
Read more at: [URL] ....
P1152 Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2
Read more: P1152 FORD Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2 | AutoCodes
Both codes come on together always. but it will go away when the sputtering clears up. I just checked fuel pressure its at 32psi at a idle.
Ford Super Duty (1999-2016) :: 2000 F250 - Hard To Drive Under 40 MPH In 3rd Gear
I recently purchased a 00 F250 psd 4x4. Other than doing all of the fixes it needs to make it ride better I have been questioning the trucks "get up and go" and the EXTREMELY sensitive skinny pedal. Truck seems to pull very hard and puts out some black smoke under hard throttle but nothing like the really tuned trucks I have seen. But the skinny is so sensitive its hard to drive under 40mph in 3rd and once it gets up to 55 or so its real sharp getting on and off the throttle. Trans shifts great, TC locks and unlocks, truck runs awesome IMO but just a bit harsh. Is there a way to find out if it was tuned prior to me buying it other than inspecting for a chip, or is this the way they are and I just have to get used to it more...?

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) :: 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) :: 2000 F250 V10 Shakes Up Until Second Gear When Takeoff From A Complete Stop
I have a 2000 f250 superduty gas v10 6.8L . I bought this truck about 4 months ago. Now when I take off from a complete stop the truck shakes up until second gear, shifts fine all the way up until the last gear it looses power "loosing power" i mean i can put my foot into the pedal and it takes forever to climb speed meanwhile the RPM'S never skyrocket like it the transmission was slipping if anything a couple times the RPM's dropped are stayed the same then as i take my foot off of the pedal once i have my desired speed sometimes not always the truck will give me a little jerk Also Just the other day I was driving on the highway and decide to put her on cruise control at about 70mph, I set the cruise control and the RPM gauge was just over 2,000 and the tach was fluctuating up and down about 1/16 of an inch. I been reading alot of forums and what I got out of them is it maybe pointing me to a misfire maybe the coil packs? Plugs?It's not something major like a transmission rebuilt.

Cooler weather has arrived and my 2000 f250 won't start. Wait to start light is coming on, no power passing through the two relays on top of the engine. Are both of these for glowplugs? My 97 only had one. How do I diagnose relays on this truck? If you cross out the two relays truck fires right off so I know the glowplugs themselves are good.

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?

Any link on how to do a flush on the 5.4L power steering pump? I screwed up on installing my new power steering pump and used power steering fluid (new to ford) and it is moaning so I need to flush and get mercon ATF put back in the lines.

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.
