Ford Super Duty (1999-2016) :: 2003 - Loss Of Power / Gray Smoke
Oct 10, 2016
I have an early 03 f350 with a 7.3 liter 298,000 miles on it
Replaced fuel filter
New oil change and filter replacement, New icp sensor .
Deleted the baffle and installed a cone air filter with the air sensor installed in the neck .
I Was driving home one day and the truck just slumped into this huge power loss . Couldn't get over 2200 rpms and barely made it over 30-40 mph.
Truck in park - idles like crap and still won't go over 2200 rpms when holding the pedal to the floor . And it has what sounds like a miss at a struggling "full throttle" (22-2500) rpms - thought it could be my icp sensor - replaced it -- no change
Checked driver side wiring harness -- no damage chafing found -- did a fuel can to pump test no difference - and today after I reinstalled the fuel line right after I ran my can to pump test I let the system prime . Started the truck and it ran for about 40 seconds and died and wound not fire back up and would just miss and spit and sputter -- lots of gray smoke though- but it fired up a few hours later after I let the batteries sit on charger .
Now before all this happened - I noticed the truck had a bit of a gutlessness to it as I would be piddling around around town and it would have this hesitation in power kind of like a slight jerking feeling , now this truck was so gutless since the day I got it ,I couldn't even burn out on a gravel road without the throttle going limp and the check engine.
Light kicking in so I figured I'd give it a bit of hotshots secret and see if It would maybe flush the injectors but it really made no difference...

A little background. I bought the 2008 F250 XL, 5.4L with 145,000 miles in December. It had a bad engine (dropped valve). I had the engine replaced with a remanufactured one (Performance Products) and started driving it this month. To date, I have put about 700 miles on it with an oil/filter change at 500.
So, here is the newest problem. Yesterday I finished changing my body mount bushings (with Daystar polyurethane ones) and went for a test drive. When I started the engine, a smoke cloud caught my eye. I took a closer look and noticed it was a gray smoke. I jumped out and ran around to smell the smoke - it had a gas smell. I did not test for smoke after my test drive.
So here is my question. It is obviously burning excess fuel on startup. That would mean that one or more injectors are leaking down after shutdown, correct? Testing this would be done by performing a leakdown test? How do I go about doing this WITHOUT any special equipment?

2003 F350 6.0L ... 171,000 miles ... 5,100 since oil change 15W-30 at the shop ...
I was driving on the interstate (50 miles of driving) struggling to maintain 70-75 mph at 2,200RPMs. I would accelerate and RPMs would go up to 3,000 but no speed. Before I could pull off speed slowed to 50 before dying. Sat on the side of the road 30 minutes before I could get it started. Had to give it gas. No misfires just quietly started. Couldn't go over 30 mph. Towed it to my destination 135 miles.
Volts on 7Pin FICM read fine.
Checked the fuel fulters. Air Filter. Tank for debris. Nothing.
My coolant reservoir was lose and I noticed a lot of coolant in the driverside front wheel well and down the left side of the undertruck. Reattached after checking FICM. Hope that was all it was cause I couldn't find any leaks.
I had Planned to have the oil changed before the return trip before this all happened. New to Diesel engines but I like a challenge. Where do I go next?

I have a serious issue with my 2004 F250 6.0. Pulling a trailer something under the hood sounded like an explosion and lost power and boost. The truck started blowing black smoke from the tail pipe. I could see no psychical damage to anything under the hood. There was absolutely no power but managed to cripple home. What happen.

7.3 auto, starts and idles OKAY, drives fine if you have a light foot but trying to go faster than 50mph or more than 2000 rpm and the whole thing has an anxiety attack. Starts sputtering and popping, lots of grey smoke when it runs rough rough, let off the throttle and it MIGHT behave nicely again.
New lift pump, cleaned the pickup tube, fuel bowl fills nice and fast, just had my edge attitude juice tuner removed since it was causing similar issues that went away for the last 2 months, changed my IPR and CPS (had a mechanic test everything when the tuner was taken out, all injectors buzzed good, sensors good)
When this first happened after the initial problem with the tuner was resolved, it did throw the CEL, but I have since been able to get it to come back on, and my buddies OBD2 scanner wasn't even registering my truck when I hooked up... Dare I say PCM is to blame?

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.

Having trouble with motor, driving home one day heard a noise under the hood. Then a lot of grey smoke started coming out of exhaust. Got the truck hauled home notice fuel was coming out at the number 7 cylinder at exhaust port. Thought it might be the injector just put rebuilt ones in, thought I might have received a bad one. I switch the number 7 injector with the number 3 injector. Did not make a difference still have fuel leaking out of exhaust manifold at the number 7 cylinder and a lot of grey smoke coming out of exhaust. Not sure where to start looking next? Could it be the injector cup is the problem?

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.

2003 f550 with 7.3, suddenly loses power and struggles while driving. White/blue smoke comes from tailpipe, can smell the diesel exhaust bad when happens, comes and goes intermittently but has been happening more and more often. I uploaded a video onto YouTube to show sound, rough running motor and smoke from exhaust although smoke not that bad in video. Search "shadetreelandscaping" on YouTube in case link below doesn't work.

Took to ford dealer a few diff times for problem and they can't get any codes, can't duplicate problem. After it being in for third time they say had to call ford tech hotline and they suggest replacing injector however can not and will not gaurntee that will solve problem, and obviously dealer isn't cheap for repair. I find it hard to believe that a bad injector(s) would be an intermittent problem as it is or that it would cause fuel pump to make gurgling sound.

I bought a 03 6.0 dually a couple months ago. Got a good price on it. I use it very little, around town sometimes and used to pull a 7000 lb camper sometimes. My issue is, the other day I took off with the camper. Drove for maybe 5 miles then stopped and waited for traffic. When I took off again it was blowing gray smoke when I was accelerating and had little power. I was going about 30 mph for about a mile at about 3000 rpm up a very gradual hill. I was in the tow setting. When I got to the top of the hill it seemed to recover. I pulled over and shut it off then took off again without any issues.
The next day when leaving camping it was the same thing. Took off and saw gray smoke and had little power. After about 1-2 miles all was well again. Truck has 202k miles. Recently replaced oil cooler, egr cooler has been welded shut at both ends, turbo has been cleaned and all the filters and fluids are new. I have a Scan Guage 2 and monitored the ficm voltage and it maintained 47 to 47.5 volts. I know 2 injectors had been replaced when I purchased it as well and the egr valve by a dealer(they said it showed the cooler was clogging but like I said it was welded shut). What I should look for?

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.

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.

So I'm not sure if I bought a lemon, but i picked up a F-350 6.4 Turbo Diesel two days ago and the check engine light came on yesterday. It's giving me a P0088 Code as well as the P0088pd. It's got 131,000 miles on it so no warranty will cover me.
I'm tracking the TSB put out telling the techs to replace the HPFP, but they mention a loss of power. I've only had the truck for two days, but I've driven them for work before and I can't detect any loss of power. Besides the code, everything seems to be running fine.
What can I can try out before running out and changing the HPFP? I'd rather not cut so deep into my savings if I don't have to.

Last night, I left it running while unloading a trailer and come back to notice it was idling abnormal. I jumped in it and tried to move it and there was a noticeable loss of power. I unhooked the trailer and tried to get it home. I only made it 1/2 mile down the road when it started spitting and sputtering (surging ever now and then) to a level that it died completely. I was able to start it back and get it out of the road but had to be pulled into a drive. It got to a point it wouldn't start back at all.
Today it started up however still had a rough idle and really has no power to speak of. The more I messed with it the less power it seem to have.
I have searched the forums and tried these things:
1) Checked the oil and noticed it was on the low end of the operating range. I put some in it to put it back to normal.
2) Disconnected the ICP
3) Changed the crankshaft position sensor
4) I dumped the fuel bowl after it completely died (in case it had any water in the fuel bowl).
The fuel filter was just changed 2 weeks ago. The fuel pump seems to be operating correctly (or it at least refilled the bowl) and started again with a very rough idle.
It doesn't have a engine light on nor do I have anything to read any codes it may be showing.

I have a 2004 f250 superduty. I lost all electric to truck. No lights, radio, etc. Turn key and no click or dash lights. I put a charger directly to battery and nothing. Is there a main fuse in power line prior to the fuse box under the dash??
Also, right before this happened, I went to start my truck and my batteries were low, the truck turned over a few times, started dying, so I turned the key off, and the truck kept turning over on its own, as if the circuit remained closed for ignition due to low battery, and it turned over by itself until the battery was completely dead. But putting my battery charger on it now gives me no electric at all.

Got a 2001 7.3 crew cab long bed over the winter and over the last week I have some electrical issues.
Leaving work I had a dead battery(s) or so I though. first though the batteries are going or the alternator going. Its a manual so i had a friend pull me to bump start it and everything was as it should. The volt gauge came right up and checked the alternator and it was OK.
Later on while driving the radio turned off and I could not get it to turn back on. At the time I didn't notice if the other cabin accessories were working
(didn't think to take notice). So, turned around a drove straight home. Once in my drive way I shut the truck off and right away turned it back on and the radio came back. I didn't know what to make of it so I just let it be.
The next morning I went to start the truck, Wait to start light went out and when I turned the key. Just a click. and the instrument panel goes dead along with all the other cabin power. when i open the door the turn signal starts clicking. So I took the batteries out (thinking that something is staying on inside the cabin and draining the batteries). I charged them at work came to find that they are holding a charge.
My issue was most definitely the GEM. So i took that out sent it to Florida and got it serviced. When got it back today and ........Same thing. I am at a loss here. Am in looking at the right things? What should I be looking for?

Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.

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 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 am trying to diagnose a problem with a friends 2002 f350 7.3L truck. the engine has approx. 140,000 miles and is all stock, no programming or aftermarket parts. Anyhow, he said driving down the road the other day the engine all of a sudden lost power and the truck wouldn't go any faster than 45mph. he said taking off from a stop sign, the truck has no power and takes forever to get up to 45mph. after this issue began, he has changed the fuel filter & screen, air filter and fuel pump. The check engine light if OFF, no active fault codes.

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.
