Ford Super Duty (1999-2016) :: 2003 - Truck Lost Most Of Its Power - Running Sluggish
Jan 31, 2015
My 2003 6.0 truck lost most of its power. It has the SCT programmer. It used to run great it would roll coal really well then it slowly started to run worse. Now it runs really sluggish especially when its cold. IT takes forever to warm up. On the freeway when ur going a constant speed it bucks and jerks a lot. It won't roll coal anymore and just runs like crap. A mechanic said I had 3 bad injectors. But I don't believe it.

I have a 2009 6.4L F250 with 153k miles on it. Yesterday I drove from downtown Dallas north to McKinney (about 40 miles) and truck was running fine. Left approx. 3 hours later for dinner and the check engine light came on and truck ran very sluggish with hardly any power. Had it checked at auto zone today and got the P040D Exhaust Gas Recirculation temperature A circuit high DTC. I can get the part but not sure if I can replace it myself.

So I was traveling thru the grapevine on the 5 Fwy and no problems. Made it to the top didn't over heat. Then all of a sudden it lost power. Pulled over and it stopped running. Won't start. Fuel is pumping, I took off the fuel filter and turned ignition on and it filled up.

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.

I drive a 2000 F250 XL Super Cab LB 2WD 7.3 Powerstroke. i drive like a grandpa. No rompin on the accelerator or anything. I was leaving the house got up to about 35mph and the truck lost acceleration. Motor still running fine. I coasted onto a side road. Put it in park, killed it, started it again and same thing. Will not go into drive at all. However will go into reverse just fine and accelerate in reverse. Desperately wanting my favorite means of transportation back!

The truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.

I have a 2003 F250 5.4 auto trans and I live in Minnesota where it has been -15 and my truck won't go. It has only half power it acts like its cutting out and it won't even hardly move in Drive if I put it in 1st or 2nd it will go or reverse but the engine is only half power the OD button is flashing the check engine light came on and I pulled the codes and there is 7 of them. I think its electrical issue but don't know where to start! Here are the codes, P0443, P0750, P0755, P0743, P0135, AND (P1747) which my book doesn't go that high?

I have an 03 with a 6.0 diesel, going down the road and started losing power and then died. Won't start, and I don't have a scan gauge. Several sources said ipr valve, and from videos on youtube I thought may be a good place to start. I bought a socket and pulled the valve, to check the screen. There is no screen whatsoever on the ipr. The oils clean, as I had changed it about 200 miles ago, and I ran a magnet in the hole looking for a screen, couldn't find anything so I used my fluid pump in the hole. No trash, screen or anything. Do some ipr valves not have screens? What would be my next step??

I have a 2004 to 250 super duty 5.4 and automatic trans it has about 233,000 miles on it. Yesterday when I started my truck I could see my reverse lights were stuck on against the garage door in the dark. After I put the truck in drive the lights went out later on I shift at the truck and to park and the starter engaged I put the truck in neutral and it stopped the starter from running after doing that several times the truck now does it even when it's in reverse or neutral. I have to leave it in drive and push the emergency brake on I am in and out of the truck all day long. I did change the shift to blast may I check the screws on the back of the shift to bury thing seems fine.

We have replaced 4 fuel pumps on a row.
Voltage is good...even ran a fresh circuit.
Ran new supply lines
But, can't seem to understand the continued drop in pressure. It usually takes about a day of driving to crater after a new pump/filter is installed.
It never dies, just loses power and drops the truck to an idle. Funny thing...if I shut the truck off and turn it right back on...full power for a short period!
The truck is used on a ranch that has plenty of rough roads...thought inertia switch maybe but i believe that would stop fuel completely right?
I am totally stumped and so is the mechanic.

Since yesterday, every time I turn the key off and remove it from the ignition the truck just keeps running. Engine, radio, according and everything just like the key was still there. When I press the unlock button it shuts everything down. It is a 2014 F250 with 4500 miles on it. I don't know if I did something or what but I am confused.

I have a 1999 Ford F350 5.4L 4x4. I had a check engine code on my truck a couple of months ago. The truck was running fine then. The light went away and I forgot about the issue. In the last week the truck began to run like crap; hesitation during hwy speeds. The truck is running with hesitation in 3rd, 4th, and 5th gear. In low gears the truck seems to run just fine. I have changed the EGR valve as well as the fuel filter. Check engine light is not on but the problem has not gotten any better.

I was driving down the highway and the truck was in overdrive and under a load passing at about 20lbs boost and all of the sudden I lost all power, felt truck shake a little. The tow/haul light is flashing and got only one code P0730. The truck won't go into gear in either forward or reverse now, had it towed home and put a pressure gauge on it and found about 100psi at idle In neutral, in reverse and forward I got strange readings the pressure goes way up momentarily then down to 100psi, and increments back up to over 500 psi and seems to stay there but neither forward or reverse engage. I have no clue what could be wrong at this point. I am attaching a video .....

I don't know what is wrong with my truck. I don't know what this symptoms called, but It felt like it was missing a beat. The engine suddenly lost power for a second or two wile driving. It did this few times. Is it the engine or the transmission? No check engine light is on. 2001 F250 5.4 V8

I have a 2004 f250 6.8L and recently I've notice the trick not running strong. Is hesitating when i step on the gas pedal. For example, I am driving on the feeder road and fixing to get on the freeway ramp, well i have to spent a bit harder on has pedal to gain speed, but it seems its struggling and I can hear muffler making like a flapping noise. Also when I am going between 40-65mph and I spent on it, the tricks kind of jerks and vibrates. Feels like its coming from transmission. I let go and step on it again and it goes away. What to check??
Miles : 96k
Year: 2004
No Check Engine Light

I have a 'new-to-me' Ford F-550 with the vaunted 7.3 Powerstroke diesel engine. The truck only has 120k miles and ran great when I bought it. Last week it began acting up. While driving on the highway, it lost power, began running rough, and once I pulled over, it died.
After a few minutes, I tried re-starting the truck, it started, but had little to no power....I could get up to 30-35mph and then it would slow down and lost all power. I let the truck sit for about 20 minutes while I refilled the diesel tank, it started right up and drove normally for another 10-15 minutes and then the same thing happened again.
The truck sat for a day and then drove normally for two entire days. This morning, it began acting up. It is the same as before..... what to do with this type of issue?
There is not a check engine light lit (yes, it works). The diesel is from a good source that is not causing problems in anything else. The truck is otherwise strong.
