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 2005 F250 with the 5.4. This truck has been one thing after another, as you can tell from my other posts. The problem this time is, if it cranks hard to start because it's cold(can be anywhere from as high as 32, but usually in the teens) it will start just fine, then several minutes later throw the check engine light. Put the scanner on, like clockwork, 4 codes, always cylinder 1 misfire pending, misfire on first 1,000 revolutions pending, cylinder 1 misfire confirmed, misfire on first 1,000 revolutions confirmed.
Sometimes you can hear a slight lope in the idle when it does this. Clear the codes, runs perfectly fine. It will never do it after it's been started for the day. Some days you would think for sure it would throw it when it's frigid and the winds been blowing on it, it doesn't bother, other days you wouldn't think it would, and it does.Can the computer think that since it didn't start right up, it misfired?
Ford Super Duty (1999-2016) :: 2005 F250 - CEL Code P1299 For Cylinder Head Temperature Sensor
(The truck is a 05 f250 with a 5.4l). The problem first started out with the engine temperature gauge spiking and then resetting itself when the truck is turned off and then turned back on. If I drove the truck for any distance it would go into limp mode and the CEL would come on. The code was p1299, which is the cylinder head temperature sensor, and I replaced the sensor but no luck. Then the shop and I went through all accessories hooked up and couldn't find a short until I remembered that my prodigy break controller would occasionally read "ol" or "sh" which both readings are from shorts. I tow a enclosed trailer about 85% of the time and the past week I have been towing it with a different 250 and the same break controller without a problem so I have eliminated the trailer. But the shop just said the problem was the controller and unhooked it.
Now the next day it threw the same code with the controller unhooked and the trailer hooked up. after thinking it seemed that it was happening when i accelerated so I took apart the 7 pin and sure enough there was a little water in it, but after driving it around for a little and no code being thrown I hooked my break controller up and it still was showing ol or sh so i believe there is still a short. Also I noticed that my voltage is reading right at 13v instead of the 13.8-14v it was reading before this issue arose. I think I have narrowed it down to the 7 pin harness and/or electrical in the break components, but do not know what would loop back to the temperature sensor.
Ford Super Duty (1999-2016) :: 2003 - Cylinder 3 Misfire With No Code?
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!!!!

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) :: 2005 F250 - Tailgate Lock Cylinder
I just bought a 'new to me' 2005 F250, Crew Cab with a v10. The Carfax showed up clean but after doing some detailing on it, I realized it had been resprayed and there was a little wrinkle in the bumper. I tried using the ignition key to lock the tailgate but it didn't work, so I'm assuming its been replaced. Need to confirm that the ignition key should be the key that works the tailgate lock or is the tailgate a different key that they guy never gave me?

I had a 05 f350 5.4 3v come into my shop with a CEL. Did the usual it had a p0307. So I did the usual again changed plug and coil plug cam out no prob they were done 15k ago. Test drove a few times and it was fine. Few days later customer brought back with same code p0307. thought maybe I got a bad plug or coil so I moved them to #6, misfire stays on #7. When I drive it local its fine when I go to pull on to highway and really put my foot in it CEL flashes (misfire) and it pings like crazy and loses all power. Scan it back at shop and still only p0307!!

Ok says injector pressure sensor low first guess was the upgrade to the blue spring. Did that code clear for a day then comes back on looking at the hfcm but kinda unsure? Came on after we got the real cold snap and i had to buy a block heater I don't see one on here i also added diesel 911 to the tank this is a 05 f250 w 6.0l....

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.
Ford Super Duty (1999-2016) :: 2002 - Misfire Intermittently - Cylinder 3 Or 4?
I have a 2002 F250 5.4 L with an intermittent Misfire. A little history on the truck in 2011 I replaced the motor with a Ford long block motor, only the block, I used my electronics, intake, etc, this was brand new from Ford. The truck has a total of over 300K miles. Recently it has developed an intermittent misfire. I have changed all the coils and plugs and the misfire is still present. The codes are showing a misfire in cylinder 3 but could be 4 too. The misfire is intermittent because this morning I changed the plugs and truck ran fine, drove to store and it started missing, turned truck off and started up and ran fine again. It has been doing this off and on for a few weeks.

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..
View 8 RepliesFord 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.

I'm in the process of replacing the clutch master cylinder in my 99 F250 7.3L. I've got the kit that includes all the components already pressurized in a complete assy. Anyway, I know that in order to remove the clutch pedal component, (the part that stick's thru the firewall) your supposed to be able to rotate it about 45deg and it should pull free from the piston attached to the clutch pedal. But, what happens when it will not come free? I've already got a new replacement kit and I can see where that stainless rod inserts into the plastic component, but I can't seem to get the one on my truck to release?
