Ford Super Duty (1999-2016) :: 2005 F350 - Misfire Code P0307
Nov 21, 2013
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!!

My dad gave his 2005 Ford F-350 truck with the gas 5.4L (?) I drove it home. If i floor it it misfires badly, or if the RPM's get over 3000 it misfires then about 3800 it stops and keeps going. but i can't give it to much gas....
The spark plugs where replaced 2 years ago along with the cat converters. I can hear some very fait manifold gasket leak ...
A few days ago it was raining and it had a bad misfire with blinking CEL. but it never threw a solid CLE. can i still put the codes on it to see what cylinder it is? Are these issue related? Where should i start?

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 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?

2005 F350 crew cab with 6.0 currently cranks but no start with a P2291 error code. Using scanguage 2 it shows icp 0, IPR 67.7, FICM 47.5 while cranking. Disconnected ICP and still no start. removed icp and hooked up air and I do not hear/see any signs of air leaking. When I disconnect the air it then whooshes out. About 2 months ago got a #1 cylinder contribution error code and changed out that injector and it has ran fine up until this issue.
Can this be a IPR? I am leading towards the HPOP, but as it costs a pretty penny would really love to make sure I tried every other avenue.
I have 197K on it, and 2 years ago did a EGR cooler delete. In May this year replaced the oil cooler, and then in August changed out the #1 fuel injector.
Oil cooler screen was broken. Cleaned the entire reservoir out. Could this just be a clogged IPR? or seeing the change while cranking an indication that it is working?

Wife took truck out and turned around after going less then a mile, saying it was running very bad. We got this truck about two months ago at a state vehicle auction. It was a state used truck, 145,000 miles, 05 Ford F350, ext cab and 8' bed. Anyway at first I thought it was valve tap until research said an exhaust manifold. With a fog machine in rear exhaust pipe we confirmed it was leaking and replaced the exhaust manifold. Figured it was probably a good time to replace spark plugs too. Took truck for a ride and she still buck and farted.
Got a code machine and got P0171 and P0174. Couldn't find a vacuum leak, but your could hear the air being sucked in. went to local parts store, guys couldn't find leak, but they said truck sounded like a steam machine. today I made a homemade smoke machine and smoke came from air intake, figured the gaskets were bad. The pictures show what I saw when I took the gaskets off. The port that has melted is the same port were the exhaust manifold was leaking from. Am in deep "doo-doo". What caused this?

I have a 2000 f350 5.4 liter I recently fixed a misfire in cylinder 1 since then every morning the truck runs perfectly fine however at night when I leave work around 6 o'clock the truck has a misfire again I stopped pullover pull the spark plug out put the spark plug back in and it runs perfectly fine all over again I don't know if this matters but when I replace the spark plug I only replaced one and not all 8 same thing with the new coil pack I don't see how that could cause this.

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 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.

2004 SD ext cab 5.4L Gas ! I have a mis-fire at low RPMs ! Autozone said it kicked out code P0316 Crank Position Sensor ( CPS ) but the CEL was not on ! So I replaced it and Still has the same problem. I checked the coil packs there good according to the autozone diagram "how to" ! I also pulled each wire 2 check the old shade tree way to see if I could tell that way. Now the CEL is on...

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 have and 05 F350 4X4. I put it into 4 wheel drive high yesterday to make sure every thing was working correctly and it was so I went to 4 wheel low and that worked fine. Problem is it won't come out of 4 wheel low. I didn't try to go back to 2 wheel when I was in 4 high. What to look for? The truck has the electric switch to engage 4 wheel.

Recently drove a 3500 mile road trip with no issues after installing a SCT X4 programmer from 5 star. Upon returning home the following week the ABS light came on and has not gone off. Additionally, last week the truck stalled while driving down the road at around 45 mph. Had something similar happen last summer, got the truck stuck and was trying to rock it in the mud and every time I shifted from reverse or forward the rpm's dropped to 500 and the truck could not respond to the gas pedal and the ABS light came on. Once I got out and washed all the mud from under it light went off and it ran fine without any warning lights.
Truck is an 05, V-10, 4x4, off road and tow package, lariat. No other mods besides the programmer.

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.

New plug on right, lower bank 2 plug on left
Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.
Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.

2005 F-350 diesel... When I first got it the radio was shutting off by its self, my 02 did the same thing so I wasn't to worried about it.
But things have advanced , radio shuts off , windows wont work? Goes on and off at will , does not seem to be road bump related as they go off and on when Im not moving.
Will stay off until I restart truck sometimes and other times it only stays off for a few minutes.

On my 05 350, I noticed the other day that my 4wd wasn't working, when I needed it of course. I quick test this morning and I discovered my PS hub is not locking in. I've read a lot of posts about it being the opposite, the auto portion causing a problem. In my case, it won't lock in in auto or manually turning. I can lock it in, spin the wheel and the axle shaft isn't turning. The pressure is the same as the other side, not too loose or too stiff. Can I pull the hub assembly off and rebuild it? I watched a video about that, but not sure on how my issue would allow me to work on it.

2005 F350 4x4... I just installed some Bilstein 5100 on all 4 corners. Stock truck. No lift.
Now every bump I go over the truck squeaks and creaks like crazy. It's embarrassing. Sounds like bushings? Truck was fine before with the stock Ranchos.
I torqued rear to 46ftlbs and front to 76ftlbs. I tightened the top nut until the bushings compressed 1/4" each.
No instructions came with them. Do I need to lube something?
This was a last minute install before a road trip and they ride great but I'm hoping the noise is something I can take care of.

2010 F350 in my shop today. so, before dismantling the entire top of the motor for this inbred oil cooler job, is there anything else responsible for the P012 engine oil temp issue? it throws the wrench icon and cuts power and i pulled the P012F code.

Just picked up new 2014 F350 lariat today and I can't figure out how to change the keypad code. I enter the factory code and hit add, but when I enter a new 5 digit code it wont let me hit enter.
