Ford Super Duty (1999-2016) :: 2001 F350 - Misfire On Cylinder 3 And 4
I have a 2001 F 350 with a V10 it keeps coming back as a misfire on cylinder 3 and 4.. I replaced all of the coils and plugs and pigtails I have even swapped out the coil packs from side to side and I still keep coming back with the same code. The truck has a bad check around 1500 RPM with a load on the motor mainly doesn't in overdrive and first starting off...

my 03 f250 has a 5.4 and i cant seem to get rid of a misfire in cylinder 3. i had a p0353 code but that no longer shows up. i replaced all the coils with Accel coils, replaced the plugs with motorcraft platinum. i have checked the wire all the way back to the PCM and it checks out. i replaced the pcm with one that has been reprogrammed. i have swapped the injector and coil with another position and still get misfire at #3. Replaced the coil connector with a new one. I have good fuel pressure. I no longer get the code but the misfire is still there, unplug the coil and injector while running and no change. Unplug a different cylinder and you can tell the change. I checked compression and its good. I am lost here!!!!

I bought this 2004 V10 Ford truck new.. It was at that time top of the line Ranch King with all the bells and whistles.. I have been trying for some time to figure out the miss I have. I was told yesterday that.. Misfire 2nd cylinder passenger side no compression.. They said I need to have a new Engine installed.. They would look for a rebuilt and would cost with installation around 5 grand.. I then took it to another garage and was told that's not it, but will check it out later in the week.. What I should look for.. No one seems to b able to figure it out.. I cannot afford a new truck at this time and 5 grand for this one to fix is not a reality..

My 5.4 F250 with 200,000 miles having many problems... It all started a few months ago, when the cam needed to be replaced, and a cam phaser was also replaced at the same time. It ran fine after, then threw a code for cylinder 3 misfire. The guy I took it to said it was due to the huge crack in the exhaust manifold and that was messing with the o2 sensor coming up as a cylinder 3 misfire. So, got the new manifold and it was good for a few weeks.
Now, starting the other night, Friday the 13th, it threw a CEL when I was coming into the driveway. It had been throwing a code every once in a while, and I brought it to school to scan it Friday the 13th but there was no code. So, I assume that it is an intermittent problem, no big deal. When I go to get in my truck to go to work a few hours later, the 5.4 cranks... and cranks... and cranks.
I get it to fire up, and it dies again. Run codes, and it says that the cam positioning sensor is broken. Replace both of them, still acts up ie. doesn't start when it does start it runs very rough and stalls. Get it up to my uncles shop, and replace fuel filter.. Still runs like trash. Run codes now, and it says rich/lean in bank 1.. My uncle tells me to move my truck out of the shop, so I start it up, and it runs great. No hiccups, it idles perfect as I move his truck out of the shop first.
I park my truck outside and let it idle for about 10 mins, and when I come back out it is still idling, perfectly fine. I get in, put it in reverse, and get about 20 feet when it dies and will no longer start back up. What could be going wrong?! Sick of throwing money into this thing! At one time while started up in my uncles shop, it was blowing black smoke, as if it was a diesel!
Ford Super Duty (1999-2016) :: Misfire On Cylinder 2 / Choppy Sound In The Exhaust
I have a 99 ford super duty with a 5.4 triton that is having a troublesome misfire. When you first fire it up it has a bit of a stutter then runs relatively smooth but the engine does still have a small shake to it and you can hear a bit of a choppy sound in the exhaust. Not completely smooth. When you drive it light footed it seems to run perfectly smooth and nice. But if you go past half throttle (sometimes you can go past that point) it starts to cough and is very slow at picking up.
When you reach between 3,250 and 4,500rpm the coughing stops. But the pick up is a little surgy, not steady. It was doing this for a while before the engine light came on. I got it scanned and it showed a miss fire on cylinder two so I have replaced the spark plug, coil, and injector but still the same issue. I opened up the catalytic converter to see if it was plugged up. Nothing there.
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) :: 2008 F250 - Random Misfire Detected On Cylinder 7
Truck Specs:
2008 f250 super duty 5.4l
78xxx miles
4x4
Automatic
Issue:
P0300 (random misfire detected)
P0307 (cylinder 7 misfire)
Let's start from the beginning...
I was getting the notorious 5.4l ticking sound. After doing research on this issue. I found that it could be a few different issues including:
Cam Phasers
VCT solenoid(s)
Loud injectors
Valves
Exhaust leak
Loose spark plug
The list could possibly go on, but these being top concerns or issues to look into.
I took it to my mechanic and wanted him to research the ticking problem. This was my primary concern due to it was getting worse over time. I didn't want to do more damage than what was possibly already done. I told him to go ahead and change the spark plugs while you're checking into what's going on. (I know those plugs can break and I didn't want to do that.)
At any rate... the plugs got changed to motocraft brand (I know the trucks can be finicky with the parts you put back into them so I went with the motocrafts to avoid any complications.) After the plugs were changed, he told me that the ticking was caused from a blown exhaust manifold gasket (yay me... not internal parts or anything too serious. Sweet!)
I had to reschedule to get the gasket done, but knowing what it was now I wasn't too concerned about driving it. So I did. The new plugs are also in the truck at this time. I drove it the next day and right away.. I noticed a misfire. Thought maybe the plug was bad. I told my mechanic about it and he said... Sounds like a COP to me.
So I get a new COP. Okay.. easy fix. Installed it and still got a misfire. Told my mechanic and he said get another COP. So I'm thinking.. "Okay.. get a new part to fix a new part.. sounds logical.. lol" so I do what he thinks might be best. I replace the COP with another new one and it's still misfiring. The new cops are also motocraft brand as well.
Okay... next step.. he claims it may be a VCT solenoid issue. At this point I don't care.. I just want my truck fixed. So he replaces the driver side solenoid. Still misfiring..
So after doing some research on the scanner... we locate some issues that are the exact symptoms I'm having. Misfire.. at low rpm.. during cruise control.. and a sudden at idle.
This information states for this drivability issue.. to spray injector cleaner/carb cleaner into the engine and possibly clean it out. Makes sense. He did this as well as changed the fuel filter. Also did a pressure test on the injectors to make sure they were good. They were. After spraying and cleaning it out, it was taken for a test drive and it seemed okay... but not perfect. The next day.. the misfire came back.
He said that if the misfire returns, that I need to contact the dealership and see if there is a pcm update. The dealership said there probably is but can't tell me until the computer is hooked up to it. (Of course there is a charge when it's hooked up) again.. whatever.. I just want it fixed. The truck is scheduled to go in next Wednesday for that. If that doesn't fix it, my mechanic said cam phasers possibly bUT still not sure for sure..
Ford Super Duty (1999-2016) :: 2003 5.4 F250 Head Gasket / Misfire Code On Cylinder 4?
After replacing most of the underside of my Super Duty, Complete front end, backing plates, brakes, rotors and shocks, I have a misfire code on cylinder #4. I replaced the plugs, cleaned the MAS and filter and rotated the coil to cylinder #1. Still have a misfire on #4 and noticed the coolant slightly low and some condensation on the oil cap. Could this be the intake gasket? My mechanic is away for 2 weeks and I think the price at the dealer will kill me. I have 63K on the truck, don't tow and plow mostly family members. It's getting a little rusty but is still in good shape.

I have a 2002 F250 superduty with a 5.4 in it, every once in awhile it starts to sputter. Its usually when i'm easing on the gas, possibly around a certain rpm and completely random. Once it starts i can get on the gas a little and it stops. i've changed to fuel filter and air filter recently so i know its not that.

View 13 RepliesFord Super Duty (1999-2016) :: 2002 F250 V10 Misfire When Driving Roughly Between 30 - 40 MPH
OK, not sure where to start so here goes. I have an 02' f-250 with the v-10. I just had some minor front end body work done and when I got it back I noticed that it just didn't feel right while driving. When I start it, I notice a small misfire while I stand next to the exhaust outlet. Nothing too bad, still runs great. Shortly thereafter I started noticing a more habitual missing while driving. Roughly between 30-40 mph and around 12-1500 rpm the truck feel like the driveline is about to pickle fork the truck. If I let off the gas or step on it, the vibration goes away. And very intermittent.
It will only do it when the truck is warmed up. If I only drive about a mile, it won't do it, yet if I turn around and head back, there it is! Now the weird part. I for reasons I won't get into, I left my ignition on and drained the battery. I just replaced it and for the last 2 days nothing. Nt even a misfire. Now today here it is again. I have read all over the forums for this exact problem and cannot find my exact problem. I have replaced the plugs with Autolites and cleaned the coils as well as the boots and applied a small amount of dielectric grease to the top of the plug. The boots are cleaned and not a sign of cracking or wear.
I replaced the PCV valve and nothing. All the plugs looked exactly the same. Light chocolate in color. Not one looked different than the other. I took them out again last week to verify the plugs weren't bad and the new ones all looked the same as well. I cleaned the MAF sensor also. Just cannot figure out what could be doing this all of the sudden. I don't see where anything wasn't plugged back together when it was being worked on and why would a new battery make it go away for a short time? Oh, and lastly, I have a superchips programmer that came with the truck and there are no codes showing and my check engine light has never came on yet.

I have a 2002 F250 SD V10 4x4, that just started to randomly misfire [does not matter if the vehicle is in motion or in park]. I scanned the OBDII and found pending code P0720 (Output Speed Sensor). The CEL, O/D light, nor the ABS light illuminate. The speedometer functions normally.
This occurred Saturday after we got 12-18" of snow. I cleaned out the driveway, took a short drive (~ miles) & parked the truck (no symptoms). Later we went to 2 stores and then on the way home, the misfire started. The next day the misfire continues.
I have been searching & come up with the same posts that say the issue is not the OSS. It's usually a bad COP or bad wiring @ the OSS. The symptoms are not the same as when I had a COP go bad (only misfired under load between 1500 & 2500 rpm).
Personal issues: My truck does not fit in my garage, it's dark (and usually below 30 F) before I can get to look at it in the evening. Also, we are supposed to get another foot of snow tomorrow night.
Ford Super Duty (1999-2016) :: 2002 F250 V10 Rough Idle / Misfire Under Load
I have a 2002 F250 CCSB Lariat 4x4 with the Triton V10, I'm up to 232,000 miles so far and fairly happy with the old girl. Just this weekend, I noticed some hesitation when at idle and even more rough running when under slight load. The misfire/hesitation is worst when going up a slight hill, when the truck is accelerating at low RPMs.
I am getting zero trouble codes or freeze frame conditions on my scanner. What should be my order of diagnosis? Vacuum test at line from PCV to TB, COP test? EGR inspection? Plug inspection? Also, how do you test a coil if resistance is not a reliable method?
Ford Super Duty (1999-2016) :: 2002 F250 - Cylinder 7 Dead - Rebuild Crate Motor?
160,000 miles and cylinder 7 is dead and 3 is dying, valves probably with rings right behind. Is it better to rebuild or buy a crate motor? Buying a crate motor, will a 5.0 fit? Should I spend the 5 or so grand beefing up this one, dropping in a 302 or putting it toward a newer model?
View 2 RepliesFord Super Duty (1999-2016) :: 2002 F250 4X4 - Front End Shaking And Brakes Began To Intermittently Hum When Stopping
Problem started with the front end shaking a little bit when braking like the rotors needed turning. Then the brakes began to intermittently hum when stopping. Then my ABS light came on. Put the truck up on the stands and disassembled the brakes on both sides. The ABS sensor was chewed up on the driver side. The less than year old hub felt sloppy so I changed it. Put everything back together.
New hub came with new ABS sensor. Went for a test drive ABS light is gone and I no longer shake or experience the hum when applying the brakes. However now when I go to stop right before I come to a complete stop the driver side (new hub/spindle side) I hear what sounds like the grade school class clown making a fart sound with his mouth, and the truck pulls to the driver side. Is the ABS system malfunctioning or is this a caliper issue? Calipers look like they are OEM.
