I have a 2004 Ford F250 with 174,000 miles the truck has a slight miss a rough idle one hot or pulling I have 2 codes nut no light when I go into the ford oem feature in my scanner a PO 272 and a PO404 .. Where to start?
View 4 RepliesI'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.
I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...
My truck died on the way home the other night. After pulling over it started right up but died three more times on the way home. Changed fuel filters, cps sensor which wasn't bad when tested, checked fuel pressure (60 psi), cleaned egr valve, fcim has 48 volts, batteries have 12 volts. Tried unplugging egr valve and icp sensor. Truck will start with icp unplugged . Ipr, stand pipes and dummy plugs were replaced last year when I purchased truck. Truck will run in park fine no issues idled normal, builds rpms and boost. Put it in drive when it gets warm rough idle and dies but starts right back up evertime. When truck doesn't die it has no power.
View 10 RepliesI have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?
I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.
While driving home the other night at highway speed my truck lost power. I just filled the tank about 15 miles before then and everything was running fine. No lights came on the dash before the truck died and now can't get it started. Bad fuel? Clogged filter?
View 5 RepliesOk I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?
Had this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.
When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.
2004 5.4 3v 2wd
CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)
The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.
And a pix of the truck in question.
I have a 00 Accent with 132k miles, I replaced the motor a year ago with a correct 2000 Hyundai 1.5 with 50k miles. I replaced everything that I could at the time, timing belt , starter, water pump, and clutch. It has been running fantastic getting 40 miles per gallon with zero problems , However in the last week I have noticed a rough idle that seems to miss with a vibration that it didn't have before. I have a noticeable loss of power and torque. My miles per gallon has also dropped to about 25 mpg. My check engine light is not on. I will check the plugs and change the air filter today but I would like to know what else could be causing the problem as I am not really sure what to check.
View 9 RepliesHave a 2004 f250 that is having issues. Once the truck is started the idle goes from normal to loud almost sounds like its going to stall. A few weeks back the same happened when i was on a red light. It choked almost to where it was going to die. I accelerated when light turned green and would not move at all. I had to literally use full throttle to get out the road at about 5 mph. I pulled in to a gas station and fueled up as i had a quarter of diesel left and it stopped the rough idle and power starvation once i started the truck up again. It sees like this time its getting more persistent... FML AND THESE 6.0 problems
View 9 RepliesI recently bought a 2004 6.0 extended cab truck. It has 223,000 miles on it and has been running great. Bought it here in Arkansas where I live and recently drove it to Texas and back after having just put some Hot Shot oil treatment cleaner in it. I ran it the 1000 miles as it suggests. Just the other day as it was hitting the 1000 mile mark the truck started to lunge/runaway and stalled. I finally got it back home and started looking into the issue. Based on what it was doing, (lunging/running away, and at idle in park random burst of rpms and then dying after doing it a few times), I started to do some research. Most of the answers I found claimed it was the IPR valve. I found that the IPR valve is supposed to, as claimed by some, be pulled and inspected every 100,000 miles are so and if need be replaced or the rebuild kit gotten for it. So I decided to just replace it as well as the oil, oil filter and fuel filters.
When replacing the IPR valve I noticed that it was original and that its screen was missing. I didn't have any problem moving the little piston in the center of the shaft with a small bolt however that doesn't really mean that it isn't bad. I tried a magnet to see if the screen was still in there and nothing came out. I did not try using a camera as I do not currently have one, to look inside the port to see if I saw it. After replacing the IPR valve with a brand new one and changing the oil I started the truck. It seemed to be running a little ruff so I let it warm up. Not one minute later the exact same thing started happening, lunging/running away (random increase and decrease in rpms), so I called it a night. The next morning I decided to change the fuel filters. No that it matters the order in which I did it, but I changed the top end filter first and the the one on the frame with the dealer recommended OEM filters as was the case with the oil. I did find in the filter on the frame that there was a small amount of sand and clay soil looking matter in the filter. I did clean out the filter housing as well.
After replacing the filters I started the truck to warm it up. I noticed that it was still running a little ruff but no random, lunging/running away (random increase and decrease in rpms). However after five minutes it started coming back. I finished letting the truck warm up and took it for a drive. Got it up to between 7-80mph for about 15 miles to try and see if I could "blow out" whatever may be in the fuel if that was even an issue I do not know. The truck seemed to get more power and run a little more smoothly so I stopped at my buddies house not to far from where I was and let it idle. No issues other than a little ruff idle. After about 10min I took off towards home doing similar speeds. I noticed at a little over 2000rpms that the truck was shaking a little but so I dropped the speed down. When I got home not more than one min after idling the same issue, lunging/running away (random increase and decrease in rpms), started happening again.
At this point I took back to the interwebs and came across a post that said the ICP might be bad and does cause this issue, lunging/running away (random increase and decrease in rpms). However I also noticed that this is a huge debate as to whether or not the ICP can cause this. Ford master mechanics say no and other mechanics say yes and round and round it goes. I decided to do the simple test many recommended which was to simply unplug the ICP and see if anything changes. Things did change. No more lunging/running away (random increase and decrease in rpms). Not more than two minutes after plugging it back in, allowing the computer to account for it now, the lunging/running away (random increase and decrease in rpms) came back. In the middle of it doing this I unplugged it and that went away. So needless to say I replaced the ICP and voila the lunging/running away (random increase and decrease in rpms) is gone but the ruff idle is still there along with a slight loss of power.
To answer some questions:
1. The oil and water are not mixing so I am almost positive that the heads are fine
2. The intercooler couplings are leaking a bit. I have ordered the new ones and will replace them as soon as they come in. Can this cause the issue?
3. I am blowing no white or black smoke except for when the lunging/running away (random increase and decrease in rpms) issue was present and the truck almost died. It would knock occasionally when it almost died and would send a slight puff of black smoke which I assume is a low or high fuel issue from the truck trying to die
4. I have not had the no start issue at all
5. I did not see any debris in the oil during the oil change
6. I didn't do the air test on the ICP port as I do not have the adapter.
7. The only code I got on the IBD II port was when I unplugged the ICP which was to be expected
8. I found no damaged wires
I am at the point where I am wanting to take it to ford to have them run a diagnostic on it but am wondering if there is anything else I need to be looking for. Here are a few questions I have.
1. Does this sound like a bad injector? (When I bought the truck it would sound like a misfire or ruff idle condition was present for about 5-15 seconds and then it would smooth out with no issues. It would run a little ruff if you tried to take off without letting it warm up, which I did once or twice and low rpms, but when it warmed up no issues were present).
2. Could this be the HPOP?
3. Could this be the FCIM? (The previous owner had replaced the FCIM not to long ago with one from Ford I believe. Said it cost him something like $700)
4. Could this be something clogging the oil screen under the manifold?
My final question right now is do any of you know where or what brand OBD II reader or software I can get for a decent price that will tell me the voltage of each injector and FCIM is without me having to go to Ford to get it looked at.
I have a 2006 f250 with a 6.0 with sct livewire, arp studs&gaskets, oil cooler, blue spring mod, sinister egr cooler and it had been giving me some real troubles lately. Started off as a code for injector #8 so I replaced that and while I was in there I rebuilt the oil rail with new nipple cups and orings, replaced standpipe and dummy plug in that bay(also updated the arc fitting less than a year ago), new exhaust back pressure sensor tube because it was right plugged with carbon, and a new egr valve because that was right packed with carbon as well, all backed together and torqued to spec from the Haynes manual and the truck still sounds like its missing at an idle with some light smoke(just smells like unburnt fuel). From there I went to test the ficm which is also only a couple years old and it seems to stay at a constant 48v so at this point...
View 11 RepliesI have a 2007 F250 4X4 6.0 diesel. When first started it idles extremely rough to a point it sounds like a old gas engine missing. But after it warms up for about 15 minutes it runs and idles like a new truck. I'm thinking it's the injectors if so is this something I can change/clean .... It's 98* on a cool day , when "cold" I mean just started for many hours.
View 13 RepliesEarly 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild
View 9 RepliesTruck has been doing this and now getting worse. 06 f250 6.0 147,000 miles. Runs like crap when you first start and truck has trouble shifting when I first take off in the mornings until it warms up then it idles fine and runs like a champ no problem shifting. Not in a cold climate 40F at the least. Not trying to take it to the dealer and get raped. Been doing research some people say get the inductive heat flash, some say needs new injectors, some say could have a bad gasket on the injector idk. I'm trying trying to get it resolved....
View 4 RepliesDad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.
View 7 RepliesI have a 2002 F-250 7.3, 159k on it. I bought it in March, ran AWESOME up till now. I was driving to work last week, check engine light came on, truck lost power and started idling rough. I have a buddy who works for a Ford dealer as a diesel mechanic, he came over with his scanner and laptop. #2,#4,#8 cylinders kept coming up saying possible problems are injectors, harness, rings.. He also did an electrical check, that all checked out. He told me to get injectors, so I got 4 injectors (yes I got the correct #8 injector), valve cover gasket, injector harness and 4 glow plugs.
The parts came last Friday, we did the job and it ran great. Drove it Friday night, Saturday, Sunday morning, no issues. Sunday afternoon we were on our way to a birthday party, truck started doing the exact same thing... Check engine light, rough idle, loss of power. After I got home from the party, my buddy came back over, put it on the scanner again, getting the same codes again. Deleted the codes, ran the tests again, same codes, deleted the codes, rant the tests again, same codes.
He said he is going to come by tomorrow with the box to check each individual cylinder.
I just installed glow plugs, ucvh, stage 2 rosewood injectors, t500, ipr and gear head tunes. I have out 97 miles on the truck since all this was installed and the truck seems to run okay but has a rough idle and sounds like there is a mis? What should I look into first?
View 12 Replies2004 F250 Powerstroke Diesel 6.0L ... 90,xxx miles
Symptoms : Within the past 10,000 miles the truck has begun exhibiting the following problems, sometimes in conjunction with one another and sometimes just independently of one another:Stalling on the road at low speed / low engine RPM.
Throttle pedal becomes completely unresponsive. Stabbing the throttle pedal repeatedly sometimes causes it to return to operation. Sometimes the engine must be shut off and re-started to return throttle pedal to operation.
Rough, surging, stumbling idle at rest. Will crank but not fire occasionally. Problem has become worse as of late. Repeated attempts at starting the engine usually result in success after much, much retrying.
Work Done : Local Ford Diesel technician replaced the EBP sensor, replaced the EGR valve and re-flashed computer with latest software -- all under warranty. Problems still persist.
Peculiarities : We have tried driving the truck with the EGR valve disconnected and with it connected, both at the technician's request.
With the EGR valve disconnected the truck usually starts fine but still stalls out at low RPM / low speed. Fuel economy is also cut by nearly 50% with the EGR valve disconnected. Really couldn't afford to keep driving the truck like this.
Technician speculated that if the truck continued to die with the EGR valve unplugged, it meant that the computer or fuel pump might be bad. ????
It also seems that the stalling problem manifests after the truck has been driven at highway speeds (65-70mph) for at least a period of 20-30 minutes. Stalling usually happens as soon as we make an exit off of the highway and begin to slow down to make exit. As in foot off the throttle pedal. Engine RPM drops then stumbles then stalls.
I wonder if this is a problem with the HPOP or ICP system.
Specifically I wonder if this is a cracked quick release fitting that allows oil pressure to fall after the engine heats up and oil viscosity thins out with the heat. Once the engine cools down sufficiently to thicken the oil, the HPOP finally gets enough oil pressure to allow the engine to fire up again.
I've had good running on the truck but lately in the cold the idle has a weird skip to it like it's missing on a cyl. It will start fine, and run fine for about 30 seconds. Then it will start to mis. When giving pedal it goes away and it's driveable but it doesn't sound right. After a bit of running it's fine for the duration while warm. My monitors are I think all good, 48.5v, icp about 1250 psi. Is this the famed "injector stiction"?
