Ford Super Duty (1999-2016) :: 2003 F250 4x4 - Misfires On Cylinder 1 / 3 / 6 And 7 - Knock P0325
Sep 8, 2014
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...

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).

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 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.

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.

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.

Ok I bought this truck with a bad engine 5.4 3v had rod knocking. I rebuilt engine got it all back together and in truck. I did replace cam phasers and solenoids. After driving 20 mins or so it would start the phaser knock at idle in gear so I put a oil pressure gauge on it and cold had 55 psi after running 10 mins or so had 15 psi at idle then would drop to abought 9 psi. I am thinking I got bad cam bearings or something for some reason don't know why. I did it but I took oil cap off where you pour in the oil. Had to force it off it was pulling that much vaccum ones cap was off oil pressure jumped up to 25 psi. What could be causing this.

I have a "rattle/knock" that I think is coming from the doors on my 2000 F250 SD extended cab. The rattle is only there when the truck is going over bumps....especially closly spaced bumps. My buddy has the exact truck and it does not rattle.

I'm new to the 6.0 fords but have bought 1 its already been bullet proofed. I've put all 8 injectors in because cylinder 3 was bad. this is my issue now you can start the truck fires right up run for 30sec to 1 min and shuts of like you turn the key off starts right back with no issues and runs fine the rest of the time until you shut it off again and there are no codes. What it could be ? I have already replaced the ipr, icp, cam and crank sensors, egr o rings and the blue spring upgrade and still does it...

I have 05 F250 SD with 150k on it. The engine has the typical cam phaser knock, timing chain slap on start up and occasionally have a noisy lifter. As long as I use fresh 20-40 oil the engine symptoms are less and the engine runs strong. The motor also doesn't leak or burn oil and the plugs were change out about 20k ago.
The truck is still good and is prefect for my needs so to me it's seems worth fixing the needed repairs. What I would like to figure out how far should I take the motor... just have the chains, guides and phasers replaced or buy a rebuilt motor and swap it? I'm thinking just doing the phases and etc would be 1/2 the cost but may not last as long as rebuilt motor. But realistically I might only put 5-7k miles are year on it anyways.

I have a noise with my new (2.6k miles) 2000 Diesel F250 Crew Cab. When I make low speed, right turns while crossing any type of depression in the road I hear a loud knock as if the left shock is bottoming out. There's an intersection near my house with runoff depressions across the road, I almost always hear the noise when making that turn. I've occasionally heard it coming from the right side when making a left turn.

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?

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!

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?

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..

I bought my 2000 F-250 CCSB a while ago and it came with 2 keys - one for the ignition, and one for the doors/tailgate - may not seem like a big deal, but it annoys me to no end.
From my understanding, the truck had previously been stolen and had the driver's side lock punched, and then something happened to the ignition lock to where it had to be replaced - hence the different key. I finally got around to replacing all the locks so that I'd only have one key. I started with the doors, then moved to the ignition (which I thought would be the easy part). I've replaced several cylinders before and I know it should be simple, but for the life of me I can't get the cylinder out!
I push the detent, turn the key to run, wiggle and pull.... nothing. I can feel the detent push in, and the cylinder will move a little, but it won't come out. I'm not sure if this is something that just happens sometimes and there's a fix for it, or if I'm in a unique circumstance and my column was somehow damaged during the theft and that's what's causing it.

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?

(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.

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!!!!

To make a long story short, after replacing the timing chains, guides, and tensioners, the right side cylinder head began running very loud. Think of the usual chatter associated with these engines and multiply it. It was constant, from start up to shut down, and it increased with rpm. Thought at first it may be caused by debris in the oil clogging the lifter(s). After changing the oil multiple times along with different additives and driving roughly 600 miles, the noise persisted. Taking a look down the oil filler tube with a flashlight and with the engine running, the head looked dry. Safe to say at this point I was starving the head of oil.
Removed the valve cover. Removed the rearmost camshaft cap. Sure enough, the oil passage was completely blocked. Inspected everything and there was signs of running dry (minor discoloration, dried oil spots... but no real damage and no play anywhere. Put it all back together and the truck runs quieter than the day a bought it.
Here's the camshaft cap:
This is exactly what it looked like after removal. The material blocking the passage is hard and bridle like plastic.
