Ford Super Duty (1999-2016) :: 2009 F250 5.4L - 2 Misfiring Cylinders
I have a 2009 f250 with 5.4l 3v. have had the truck only about 6 months. it started missing about a month after I got it. I replaced all 8 cops and all 8 sp. The truck ran excellent until 11/29, then I got a cel and the truck started running really bad. Found 3 misfiring cylinders. Changed all 3 cops again and that did nothing. Pulled the injectors and found 2 of them were clogged, replaced those also. Still no change was told by someone that the ecm/cpu may need to be reset, did that also. Still no change. There are no codes present but still has the multiple misfires.

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.
Ford Super Duty (1999-2016) :: 2011- Misfiring On All Cylinders?
SO this truck came into the shop yesterday with a really bad misfire. pulled the codes and got a misfire codes for cylinders 1-6 and also p1450 (unable to bleed fuel tank vacuum) and p068a (pcm/ecm power relay de-energized too early) i found a TSB related to the issue, TSB 10-25-7 i did as the tsb told me to do and pulled valve covers to check out the rocker shaft rollers and inspect for any signs of surface deformation or fatigue. they were fine on both sides.: ive got spark in all cylinders. fuel pressure was right around 55-60 the gauge was fluctuating pretty good. checked for bad fuel or water in fuel ect. fuel seems to be good. pulled O2s incase of plugged cats still ran like crap.

I've got a 2015 F250 with a 6.2 Liter with no compression on 3 cylinders. The dealer just diagnosed it and has not opened it up yet but the mechanic says it is probably a broken valve spring...that it is not uncommon in this engine.
My concern is not repairing the spring my concern is what a "free spinning" piston in 3 cylinders does to the life expectancy of the main and connecting bearings in this engine. I have rebuilt engines in the past and I have bought re-built from auto parts stores and from Jasper and I have never had any last more than 60-70K miles. It seems to me that even with very little mileage on the engine with three of eight pistons jumping around under no pressure that there could be considerable scarring of the bearings or bearing surfaces. I am no expert by any stretch but this is an engine in atruck that has less than 22K miles on it and I ain't real happy about opening it up let alone trusting for the next 280K miles that the bearings have more wear on them than they should have. It was only driven about 20 miles total like this but that is a lot of pressure on a highly tuned and pretty darn precision machine.
This is the newest vehicle I have owned since 1988 and I meant for it to be the last pickup I drive (I drive 'em til the wheels fall off) but I am not overly confident that even if this is a one off problem that it hasn't caused even more damage that won't show up for another 100K miles or so???
Ford Super Duty (1999-2016) :: 2000 F250 5.4 - No Compression On Cylinders
I have a 2000 ford f250 5.4 2v that's been having a shaking at idle and no power what so ever. I tried diagnosing it myself and came up with nothing. I finally decided to take it to the dealer and they are telling me that the right side has no compression on 3 cylinders. They want almost 7000 for a new engine. I was wondering if it was possible to get away with just putting a new head on the right side?

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.
Ford Super Duty (1999-2016) :: 2002 F250 - Misfiring Under Heavy Load Or High RPMs
So basically I thought it would be a great idea to degrease my motor from the top down.... After washing I start it up and drive down the road to head abunch of misfiring under heavy load or high rpm's.
My problem is that the misfiring won't throw a code. I then proceeded to buy a new ignition coil (thinking this was the problem) but with no code to go off which cylinder was bad I just switched the good ignition coil into each cylinder and starting it.
Up each time. None of them seemed to make it better. Also the injectors all seemed to be good. So what to do ?

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.
Ford Super Duty (1999-2016) :: 2002 F350 - Cylinders 4 And 6 High To Low Side Open
Alright, so here's what I've got: 2002 Ford F-350 7.3L - Unmodified, Stock, no chip, no tuner, 130K miles, been run with off-road diesel most of its life as a farm truck.
Here's what it's doing: Serious misfire in cylinders 4 and 6. At idle, mild miss. Throttle from 0 to 50 percent, runs well. Throttle from 50 percent to 100 percent, heavy miss, chugging, white smoke out the exhaust.
Here's what we've done so far:
New UVC Harnesses with updated pigtails.
Cleaned Fuel Filter Mixing screens.
Cleaned out fuel tank.
Cleaned bowl.
Changed Fuel Filter.
Changed IDMs
Changed Crank Sensor.
Inspected injectors while running to see if oil is pumping (it is).
No improvement. Where to go from here. Pulled codes, and it says Cylinder #4 and #6 High to Low Side open. We don't know what to do at this point.

My daughter has this truck and I was driving it the other day I noticed it misfiring when the trans shifts down under a slight pull and/or going up hills. It looses power and speed when this happens but if you back off, it smooths out when it shifts into overdrive. I haven't had it to a mechanic to check any codes yet.

While driving into town during a recent snowstorm, my truck started to misfire quite badly. The check engine light started to flash and then remained on as I went to the auto parts store. The code indicated cylinder two misfire. I don't a few things of dry gas in the tank and let it run for a few minutes which seem to solve the problem.
Since then, however,every time the engine gets even a little bit wet it starts to bark again. It usually lasts a few minutes then goes back to normal. Typically, I would have replace the plug wires. When I lifted the hood of my truck I realize I knew nothing about it.
Ford Super Duty (1999-2016) :: 2005 F350 - Low / Tow Overdrive Light Blinking - Number 8 Cylinder Misfiring
I have been having some inconsistency with my transmission in my 2005 F350. I bought it used 2 months ago and have had the low/tow overdrive light blinking. a month ago I removed the pan and changed the filter in the transmission. I had a friend run the diagnostic test and found transmission solenoid code as well as both cat. converters as well as my Number 8 cylinder misfiring... I pulled the transmission pan and filter to find what appears to be 7 solenoids? Where to start?
