Ford Super Duty (1999-2016) :: 2000 F250 V10 - Multiple Misfires / Engine Shakes Quite Noticeably Over 40 MPH
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.

I have an 2003 F250 7.3 Diesel 4wd. Yesterday I knew I was low on fuel but I don't think I ran out of diesel. My gauge was above the "E". 50 miles left on my overhead readout, but you never know. All of a sudden the truck misfires and is running very rough before it dies on me. I get it towed home.
Thinking that it possible I ran out of fuel and screwed up my fuel pump, I bought a new fuel pump and fuel filter, installed them and I have the same symptoms. I am guessing I lost my prime, who knows. I have 180,000 miles on it and haven't ever had engine problems.
Ford Super Duty (1999-2016) :: 2006 F250 5.4 - Engine Misfires?
Ok I rebuilt the engine in my f250 5.4 3v. Timing set cam phasers and oil control valves are new. The problem I'm having that just started after 5k miles on a new engine is all of a sudden i will start getting misfires 1st time it happened said #6 i changed coil same problem came back this time said multiple misfires now I'm just getting #4. When the misfires happen if i hold throttle where it is it will misfire as long as i hold it there if I let off gas then apply right back misfires stop for several miles then will happen again. I have changed fuel pump and fuel pump driver module same problem exist.

2003 F-250 SD 4x4 w/5.4L engine and 4R100 trans (pic in sig) . Truck has 280K on it with about 40K on a partial rebuild on the top end.
Took the truck out offroading and got about 4" from the top of the 33" tire in water (not mud.. water) . Someone with 6' tractor tore through the puddle.....
Well the truck survived through it ... albeit dirty as all hell and developed some issues soon thereafter. Codes for misfires on cyl 1,3,6,7, general ignition coil, etc etc etc
Power washed the underbody , washed the mud off the engine bay (yeah... with water but given it was caked with mud and water to fill the plug wells... no additional harm) .
Replaced all 8 COP and 4 plugs ( easier ones to reach), oil change, oil filter, new paper cone filter. checked most all the harness connections and cleaned with alcohol also. Reset the PCM/ECU and drove the truck for about 100miles and finally just after putting a full tank of gas (92 Octane) I throw a P0325...
The engine runs very clean, no hesitation, smooth idle, smooth acceleration on both light and hard acceleration. Just the damn code. Is it the gas I just topped off? After 100+ miles with new COP and plugs it threw nothing until this and runs great. Dont hear any knock/ping/detonation by ear and feels silky smooth at idle.
I really dont want to have to tear the intake off to replace bank 1 knock...
Ford Super Duty (1999-2016) :: 2012 F250 6.2L - Misfiring On Multiple Cylinders
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.
Ford Super Duty (1999-2016) :: Spark Plug On Cylinder 4 Is Sitting Level With Hole - Misfires
2001 Ford F350 V10, 220K in crap condition
First of all on the left side 2 of the coils were so withered the rubber separated from the bolt and were loose. Without any tools I was able to remove 2 coils. Typically there is the hole and several inches inside hole is where the spark plug sits.
On cylinder 4 the spark plug is on a funny angle and is level with the hole or possibly poking up above the hole. Tried sticking the ignition coil over the spark plug but it wasn't correct. Leaving it alone until my cousin can take a look. Spark plug was tight but I didn't put a ratchet on it.
Wondering, is this the infamous spark plug blew threw the cylinder thing. Wish I would have taken a picture (I will next time I'm with truck).
Had codes for misfires on 4 cylinders but that was with 2 coils unplugged (way I got truck at auction)....I replaced 3 of them (1/2/6).Cleared codes...4th cylinder remained unplugged....And the only code I got after letting truck idle for 10 minutes was something about ignition coil D (which would line up with cylinder 4 I think).
Ford Super Duty (1999-2016) :: 2008 F350 - Multiple Codes / Cylinder 5 Misfire
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.
Ford Super Duty (1999-2016) :: 2005 F250 - Multiple Misfiring Codes / Stumbling When Come To A Stop
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 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.
View 1 RepliesFord Super Duty (1999-2016) :: F250 Pulling To The Right Randomly?
1999 f250 5.4L... Its done this 3 or 4 times now. Driving and it starts pulling to the right pretty bad, almost like if the front passenger tire was messed up or something. Today it did it, after I let it sit for a few min, then drove back to the house, it drove straight. Also, when it pulls to the right, its very sluggish, as if I'm pulling a very heavy load. From a stop, it doesn't even go until I hit the gas, and at that its very sluggish, sorts feels like if you drive off and forget the ebrake is on.
Also I've noticed some burning on the passenger side which I've read is probably the head gasket. I can see the oil dripping on the exhaust, causing the smoke. Also, my CEL just came on, with code P0401 "powertrain exhaust gas recirculation flow insufficient detected". Recently changed the plugs because it was running and idling a little rough.
At this point in wondering if the pulling issue could be something with the brakes, when I'm driving, it sounds like something is rubbing, I haven't looked at the brakes yet but I'm likely going to do new pads and rotors all around soon anyways.

View 5 RepliesFord Super Duty (1999-2016) :: Stalling Randomly While Driving And Sometimes Not Restarting Right Away - Bad PCM?
I have a 2005 f250 5.4 auto trans and the past few days the truck has been stalling randomly while driving and some times not restarting right away. Now today it stalled a few times. once while driving, once when i sitting in it trying to load up obd2 scanner. I got it home and it started running rough for 2 mins then it would stall out. It did that 3 or 4 times and now it stalled while sitting in drive way and wont start at all. it wont crank. no fuel pump noise any more.
The odometer goes out and just has a bunch of flat lines. I can not get scanner to connect anymore. it never had any codes before when it was stalling. When I could get scanner to work it had 42psi of fuel pressure. battery and starter are good. all the fuses are good and I can hear the pcm relay clicking when I turn the key and swapping relays does nothing. I can hear a very rapid clicking noise from the throttle body area. What that could be? is the pcm fried? what would cause it to fry? how can i test pcm? if get used pcm does dealer have to program it?
Ford Super Duty (1999-2016) :: Intermittent Grind Sound That Would Come And Go Randomly
While on the way back from the deer lease last week my '99 f250 sd 4x4 5.4l started a grind sound that would come and go randomly. Lasts about 1 second. Seems not to change the way it drives. The dealer had it for 2 days and couldn't find anything. This happens at freeway speeds 55-70 mph.

I recently bought an 03 F-250 6.0 Lariat crew cab FX4. It has an EGR delete, ARP studs, and the updated oil cooler. It has 138,xxx on the clock.
Randomly, only when it is at normal operating temperature it will have a slight shake to it at idle. when i try to take off from this shaky idle it feels like it is "missing" i guess you could say. it clears up about 1/8 a mile down the road every time. And i will go ahead and say this does not happen everytime it idles. Only maybe once or twice in a 30 minute trip.
What might be going on? I have not added a coolant filter yet, and it does not have synthetic oil in yet either (just bought it) I plan to use full synthetic Rotella 5w40 very soon. I think this might be a stiction problem? but i read it is uncommon to have stiction when warmed up. I do not have anything yet to pull codes or read the FICM yet. both batteries are good.

I have randomly getting in my sd. It is an 08 f250 xl with a 5.4. randomly my truck chime at me, hence why I haven't been able to capture it on video. It will chime twice. The sound is a subtle bong, bong. It is never predictable and never affects anything, but is annoying and I am curious as to why it does it.
View 14 RepliesFord Super Duty (1999-2016) :: 2003 - Hesitation / Truck Shutting Off Randomly
I have a 03 F250 5.4 4x4 auto, last year I had a problem with the truck shutting off randomly. So after doing all the dumb stuff and research I ended up concluding that the FP relay was acting up and my understanding is that, it is located in the fuse block. So not wanting to replace it I wired up my own relay next to the safety switch in the passenger side kick panel and it has been fine ever since. I did put a new pump in it (Cali emissions) Now to present day-
Over the past month my truck would have a slight hesitation problem when accelerating on the highway/up grade. The issue was it would go away for a while when you would shut the truck off and be good for a while. Well then it started happening all the time.
I knew I was do for a tune up (215,000) so I did all the plugs, COP's, fuel filter and a PM. It got a lot better but was still there at the top end. So after doing a lot of research I found a lot of people having the same issues, so for testing purposes I cut the CAT out and installed a section of flex pipe. (Iwill be installing the cat back in)
So last night I take it out and its even worse...I went don to my buddy's place and hooked up a Versus and got no codes at all, no misfires on the counter..absolutely nothing. So I did what I should have done in the beginning and duct taped a fuel pressure gauge to the windshield and took off.
At idle I have 30 or so PSI, and when it was fine it would stay around that, when it started acting up it would drop to 5-2psi under load and go back to 30 or so PSI at idle. The other thing is now I only have 1/4 tank of gas.
What I am concluding is that the pump is getting hot and weak, because when I had a full fuel tank it was better and now I have less fuel to cool the pump and it is happening faster. Should I just throw another new pump in it? Or go after a voltage problem to the pump?
