Ford Super Duty (1999-2016) :: 2000 F250 V10 - Multiple Misfires / Engine Shakes Quite Noticeably Over 40 MPH
May 7, 2013
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 99 v10 is having a random multiple misfire, it showed an 0300 a few weeks ago. since then i have replaced plugs, 2-cops/boots,dpfe,egr, did a vacuum check,fuel pressure at 28, and i'm sure i'm forgetting something. I drove down to napa today for some sea foam (15 miles) and it drove like new, when i started it up to come home it started missing again, it starts easily and i can press the gas and go, but i can still feel the misfire...

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.

Alright i got a 2000 f250 with the 7.3 and its stick, when i let off the clutch to start moving, and at low speeds like mainly 1st and 2nd gear. Right below the cab there's a loud kinda growling or rumble, it shakes the truck a bit til i start moving good. Then it goes away. But what it could be? I think pilot bearing.

I have a 2000 f250 superduty gas v10 6.8L . I bought this truck about 4 months ago. Now when I take off from a complete stop the truck shakes up until second gear, shifts fine all the way up until the last gear it looses power "loosing power" i mean i can put my foot into the pedal and it takes forever to climb speed meanwhile the RPM'S never skyrocket like it the transmission was slipping if anything a couple times the RPM's dropped are stayed the same then as i take my foot off of the pedal once i have my desired speed sometimes not always the truck will give me a little jerk Also Just the other day I was driving on the highway and decide to put her on cruise control at about 70mph, I set the cruise control and the RPM gauge was just over 2,000 and the tach was fluctuating up and down about 1/16 of an inch. I been reading alot of forums and what I got out of them is it maybe pointing me to a misfire maybe the coil packs? Plugs?It's not something major like a transmission rebuilt.

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.

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.

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...

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 just bought this truck for a pretty good price it has 225000 on it the engine was over heating. The guy put new rad, new water pump, new fan clutch, and a new heater core with thermostat. The truck still over heated so I pulled the thermostat to see what happens and the truck over heats even faster. All this happens while driving regardless of ac on or off. I got a motor and put a motor in it with all new pump and thermostat. I put new coolant in and flush radiator. I cut a hole in the cat to see if the cat was plugged for the truck seems to have low power and sputters. With in 1mile the truck over heated dumping all the coolant out of the system which the truck did as well before. Will the diesel rad work in this truck I have a diesel one I can put in since its a bigger rad?

I bought my 2012 F250 CC SB 6.2 back in December and really haven't had the truck in 4x4. Today we got a bit of snow. The roads were slippery so I engaged the 4x4 ESOF while at a stop sign (I know, didn't have to be stopped but I was so I put it in 4x4) The driveline was noticeably louder.
I had a relatively constant hum that almost reminded me of a wheel bearing going bad. If you've ever experienced a wheel bearing going bad the sound gets louder as you go faster. I'm sure it's not a wheel bearing since it only makes the sound in 4x4.
It's a fairly annoying sound and is louder than my old 99 F350. Notice the driveline being significantly louder in 4x4? There are no driving issues just a louder sound than what I was used to. I have the full Ford Certified warranty and can bring it in but I thought I'd run it by the brain trust here to get thoughts before going to the dealer.

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.

So I took a trip from Dallas to Florida, and on the way back my check engine light came on. The car shakes at idle, almost like it wants to take off. I drove it back to Dallas like that since the car runs normal on the high way. I got it scanned at autozone and the code said it had multiple random misfires. I'll be taking to the dealer in the morning, but what it could be? The car jumped over 50K during the trip hopefully the dealer will be nice and cover it.

2000 f250 7.3. Today I tried using the 4x4 and no light or anything. Here is what i have tried so far. Swapped the relays and also swapped them with the towing relays with no change. Not getting any voltage to the t-case shift motor at the selector switch testing between pins 2 and 3 there is 4.3 volts with switch in 2wd 2.4 volts at 4 high and 1.09 volts at 4 low. Where to go from here? it worked fine 3 days ago.

I just bought the truck and the ac was working and now out of nowhere when you turn it on it just blows hot air so I just assumed it was out of free on so I bought an ac pro but that did nothing.

I have a 2000 F-250 V10 that misses (cylinder 10) at the idle, once you give it gas it runs correctly again. I am at a loss. I have replaced the plug, tried moving coils from one cylinder to another to see if it shifts the miss, and it has new injectors. What this could be?
