Ford Super Duty (1999-2016) :: 2005 F250 - Multiple Misfiring Codes / Stumbling When Come To A Stop
Dec 14, 2009
My '05 F250 (5.4) started misfiring and threw codes for p0300, p0305, p0307, p0308,and p2198. I used an inline spark checker to check cops, which all had spark. Replaced 5, 6, 7, and 8 plugs and cleared codes. Ran truck for a few minutes and codes came back. Switched #5 and #6 cops and cleared codes. 5,7,and 8 cylinders still misfiring (same codes). Truck only has 36,000 miles and spent alot of time just sitting. Plugs were original plugs.
Replaced 5-8 with Autolite OEM replacements. I haven't checked cops for resistance yet. Weather was pretty cold when problem started. Threw in about 10oz. of Lucas to no avail. I had this problem last winter with the same cylinders throwing codes. Threw some Lucas in the tank and idled truck for approx. 1/2 hour and problem went away except for stumbling most every time truck came to a stop. I'm starting to wonder if it's a coil or a fuel issue.

I have a 2012 F250, 6.2L, Crew Cab, FX4 with a little over 77,000 miles on it. I bought it used from a Ford dealership last summer. Prior to now, I've only had one issue with it and that was squirrel/rodent induced. Something chewed through the wiring harness right before the connection to the #7 cylinder. There was enough left over wire to solder it back together and put heat shrink around each wire.
It ran fine up until last weekend. The wife and I went to a store, she was driving and parked like a total jerk right in the front area of the parking lot. When we got back in the truck, she started it up and it was just running rough with hardly any power. My first thought was someone dumped something into the gas due to her amazing parking, but there were no smells or residue of anything near the gas cap when we got home only a couple miles away.
When I got home I ran my code scanner and found 300, 301, 305, 307, and 308. I dumped a bottle of ISO-Heet in it, let it sit for a bit then cranked her up and ran it for a few miles to the gas station and filled up...about 25/26 gallons, I don't remember...I was a little above 1/4 tank when this all started. No change in performance and the codes were all still the same. I pulled the MAF, it looked clean, but I wiped it down anyways and threw it back in. No change. I then changed all the plugs. This took care of 301 and 305 but 300, 307, and 308 were still coming up. I then picked up two new coil packs for cylinders 7 and 8, threw them on and still no change.
I sat with it running on a flat surface for a little while revving the engine randomly for about 15 minutes, during this I noticed a fast tapping noise at about 3400 RPM, it went away quickly with no changes in the gauges on the dash. I cant really tell where it's coming from, but kinda sounds like its under the middle of the truck. While sitting there I ran the codes again, and now its back to 300, 301, 307, and 308. I'm now at a loss of what to even look at...
I've also checked the voltage coming off the harness at the connector to the coil packs...just under 11 volts. I've searched all over for what that voltage is supposed to be, but have failed miserably in my searches.

05 5.4 F250 4x4. Keep getting those codes. Can't find any vacuum leaks. swapped rear O2 sensors. Fuel filter twice in last 11k miles last time was 1k ago. Will the 430 code cause the lean codes from a bad cat? I've been getting the 430 code for at least 4 mo's.

My 2005 f250 5.4 with codes p0171 and p0174. I have replaced fuel filter, MAF, Checked for vac leaks by smoke and water test.
I don't have a way to check fuel pressure on this thing since it must have been to much trouble to put that test port on the fuel rail!!!

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 just got my 2005 F250 diesel out of the shop. The errors codes P0299 and P2263 were listed on the computer. The service done, was to clean carbon from turobo charger and service the EGR valve. I talked with the mechanic and he recommended that I use Cetane Booster Additive. What would the Cetane Booster do? How would it prevent the carbon build-up in the turbocharger? What should I do to prevent turbocharger carbon build-up?

After finding that a battery was low and not getting charge, they found the alternator was bad. Replaced that. Next the battery that was low was able to be charged and did not effect the other battery. Both batteries have been load and charge tested and they both read 84% charged. I am told this is "good."
Next I swapped both fuel filters and did the oil change as well. I finally got a chance to get my friend to run his scanner on it. The results are injectors and FICM. The codes are PO261, 264, 267, 270, 273, 276, 279, 282, and finally 611. I guess this means that the FICM is toast.
I have tried salvage and no one has anything. I guess I still don't understand how this truck is capable of running daily with the computer throwing every code dealing with the injectors and the computer that runs them.

My dads truck started misfiring last week, first thing i did was scan the codes and got p0303, p0304, p0305, p0306, and p0308. Its an 08 F-350 5.4...already changed out the spark plugs and the same codes came back. I decided to do some further testing and so far all coils had spark as well as 12.4 volts going to each. I did check the switching signal and that was present as well.
Moved on to the injectors and i checked each connector with my noid lights and it flashed on all cylinders. Did a resistance check on each injector and they all registered 12.4 ohms. We did switch some coils around and all the same cylinders misfire. My next step is to do a compression test.
My biggest question is if there are any common problems with these engines besides the coils, by the way this truck has the brown coil boots and the spark plugs that dont break in the engine.

2005 F250 6.0L ... My truck is running really rough when the engine isn't all the way quite warmed up. once the truck is fully warmed up to normal running temp it runs good. I am getting four engine codes. P0672, P0673, P0674, P0676 These codes say 2,3,4, and 6 glow plugs have a open circuit. Can this be the cause of my problem?

I have a 2006 F350 SRW 4WD 6.0 with 127000 miles on it. A couple of weeks ago it, pulling out of my driveway, it hesitated and tow haul started flashing. I had codes pulled and it showed P1780, P0751, and P2700. After turning off, codes were gone and tow haul off. Ran fine since then every day. Yesterday while going about 50 mph it started acting like it was in neutral (revving up), nothing happened when mashing the accelerator. Coasted to a driveway and truck would not move, only sounded like it was in neutral.

I just bought a 99 F250 Super Duty with the V10. When I bought it, I knew it had 2 misfiring cylinders (4 and 10) because it was throwing P0304 and P0310 (only 2 codes), but wasn't concerned as I've had to take care of my wife's Escape with it's misfiring cylinders. I replaced the 2 coils and replaced the plugs with Motorcraft plugs from O'Reilly's, cleared the codes and she ran fine for a couple of days. Now I'm getting an intermittent misfire, it's only occasionally throwing a pending code of P0300 which is "Multiple Random Misfire".
I'm fairly certain it's an issue on the electrical side because if it were an issue with the injector or injectors it would be constant regardless of RPM... right? As it is now, it basically does it between 55-65 while in overdrive trying to pull a hill or slightly accelerate. Once it's shifted out and the RPMs go up to 2k+ it runs like a champ... and it kills my fuel economy. The way it's behaving is just like when a coil is bad, but it's saying it's not identifying a specific cylinder (saying it's multiple) and it doesn't always do it (about 60% of the time).
I checked the MAF and it's very clean (looks almost new), checked the vacuum lines (those I found without a manual) and couldn't find any leaks and when I changed the plugs all the plug wells were dry.

I have a 2009 f250 with 5.4l 3v. have had the truck only about 6 months. it started missing about a month after I got it. I replaced all 8 cops and all 8 sp. The truck ran excellent until 11/29, then I got a cel and the truck started running really bad. Found 3 misfiring cylinders. Changed all 3 cops again and that did nothing. Pulled the injectors and found 2 of them were clogged, replaced those also. Still no change was told by someone that the ecm/cpu may need to be reset, did that also. Still no change. There are no codes present but still has the multiple misfires.

i have an 04 f250 5.4 4x4 250k miles+ ...the truck has been acting weird lately. I has 0 power...i went to pass an 18 wheeler today at about 15 mph and gave it about half throttle...well it held first gear till about 5 grand then slammed into 2nd...It just has 0 umph ... it wont even consistanly pick up speed at half throttle or over..the rpms will stop ...then pick up...then stop...it always accelerated smoothly....it is bogging really bad...it was downshifting into 3rd today on little overpass hills that it NEVER does that on...something is telling me torque converter BTW no codes and no flashing overdrive light

I have spent alot of time looking through threads about v10's misfiring and have not been able to resolve my issue. I recently purchased a 2000 v10 f250 with about 220000 miles on it I bought it knowing it had one miss fire but now I have a total of three. Te truck has no problems accelerating but at a little over 40 mph the engine shakes quite noticeably and after 60 i5 seems to smooth out. After alot of reading I replaced all of my plugs and ignition coils, ran a can of sea foam through my gas tank and my intake with no change to the miss fires. I have started my trials with the fuel injectors by switching them from miss firing cylinders to ones that aren't. Some other information is my truck has no egr on my intake.

My 2008 f250 6.4l just got out of the shop a week a go new small block and new pistons, throwing #1 constrabution code,map sensor and #1 cil misfire you can hear air come out of the intake, I am guessing valve train or lifter..... other problem two days after the truck throwing the codes i went to take it to the shop and would barely drive floored struggle to go 10mph put it in park rev up normal will go in reverse normal just no power in drive, no transmission codes, had it towed to the diesel shop, mech said might be a fail safe on transmission from the engine codes? it has egr/dfp h&s mini maxx tuner, the truck has 170k on body 11k on new engine before the new block that was put in last week.

So basically I thought it would be a great idea to degrease my motor from the top down.... After washing I start it up and drive down the road to head abunch of misfiring under heavy load or high rpm's.
My problem is that the misfiring won't throw a code. I then proceeded to buy a new ignition coil (thinking this was the problem) but with no code to go off which cylinder was bad I just switched the good ignition coil into each cylinder and starting it.
Up each time. None of them seemed to make it better. Also the injectors all seemed to be good. So what to do ?

I have been having some inconsistency with my transmission in my 2005 F350. I bought it used 2 months ago and have had the low/tow overdrive light blinking. a month ago I removed the pan and changed the filter in the transmission. I had a friend run the diagnostic test and found transmission solenoid code as well as both cat. converters as well as my Number 8 cylinder misfiring... I pulled the transmission pan and filter to find what appears to be 7 solenoids? Where to start?

Where to start. Have had to replace a few COP's in the past and replaced all spark plugs 20k ago. Truck runs rough at idle and sometimes stalls when changing gear. Strong exhaust smell when sitting idle. If I put my foot in it there is hesitation. Engine seems to smooth out quite a bit but also seems like it's getting more power in stages. Codes P0426 and P0345 ....

Ok so my F250 died last night. I read the Pcodes and came up with P2198 and P0506. I am pretty good with fixing the truck but need to know exactly what is wrong.
