Ford Super Duty (1999-2016) :: 2000 F350 V10 - Misfiring And Shuddering
I have a 2000 f350. When idling uo can't really hear the miss. Driving at about 40-50 mph it will shack and shutter real bad. Hooked up spanner and had miss fire codes for cyl. 1,4,9. Changed out all 10 plugs, and boots. Also changed out the coil on all three cyl also. Still have the miss and shutter. Also changed out #9 injector ...

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.

My 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.
Ford Super Duty (1999-2016) :: Check Engine Light Turns On Randomly And Goes Off After A Couple Of Seconds
I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.
The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.
I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.
I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?
Ford Super Duty (1999-2016) :: F250 V10 - 2 Misfiring Cylinders
I just bought a 99 F250 Super Duty with the V10. When I bought it, I knew it had 2 misfiring cylinders (4 and 10) because it was throwing P0304 and P0310 (only 2 codes), but wasn't concerned as I've had to take care of my wife's Escape with it's misfiring cylinders. I replaced the 2 coils and replaced the plugs with Motorcraft plugs from O'Reilly's, cleared the codes and she ran fine for a couple of days. Now I'm getting an intermittent misfire, it's only occasionally throwing a pending code of P0300 which is "Multiple Random Misfire".
I'm fairly certain it's an issue on the electrical side because if it were an issue with the injector or injectors it would be constant regardless of RPM... right? As it is now, it basically does it between 55-65 while in overdrive trying to pull a hill or slightly accelerate. Once it's shifted out and the RPMs go up to 2k+ it runs like a champ... and it kills my fuel economy. The way it's behaving is just like when a coil is bad, but it's saying it's not identifying a specific cylinder (saying it's multiple) and it doesn't always do it (about 60% of the time).
I checked the MAF and it's very clean (looks almost new), checked the vacuum lines (those I found without a manual) and couldn't find any leaks and when I changed the plugs all the plug wells were dry.
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 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) :: 2000 F350 V10 Engine Seems To Have A Miss
I have a 2000 F350 cab and chassis 4X4 with V10 and a 5 speed manual (actually it's a 4 speed with overdrive). My problem is the engine seems to have a miss in it. When I first start it in the morning it usually runs good for 5+ miles till it warms up then if I am not pulling a load I can hear what sounds like a miss but the truck accelerates fine. If I am pulling a load I can also feel a slight steady consistent shudder and I can tell the truck doesn't have the power it should and the gas mileage SUCKS worse than it use to.
I ran a bottle of Lucas deep clean through a tank of fuel and that seemed to work a little but I will still encounter the problem sometime during the day. When the miss seems to be gone I can hear a very slight pinging noise when I accelerate or pull a hill with and/or with out a load. The pinging noise I hear sounds like an engine with a distributor that is getting to much spark advance if you have ever experienced that before.
I purchased this truck used several years ago and I don't know what the PO did but the check engine light is not coming on and it doesn't throw a code. I put 10 new ford coil packs on it about a year ago so I really don't think it's a coil pack, but I could be wrong. To me it sounds like maybe it an injector problem????? I know there are several sensors on this engine and I am thinking maybe a crank position sensor is not working right but I honestly don't know???? Is there a way to test this sensor?
Ford Super Duty (1999-2016) :: 2000 - Engine Shuts Off When Key Released?
I have a 2000 F-250 with a 7.3l turbo diesel.
It's been running great but recently I've noticed an issue with starting.
When I turn the key and the engine starts when I release the key it's like the engine stops for just a second and then starts running again.
After it's started it doesn't seem to have any issues but I'm concerned and would like to nip it in the butt before it because of a real issue.
Ford Super Duty (1999-2016) :: 2012 F350 Misfiring When Driving During A Snow Storm
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.

I turn off the key and remove it. The engine shuts down but everything else stays on, the radio, heater fan, etc. I tried to search the forum but couldn't find anything about this problem. I'm guessing there is a stuck relay or a bad ignition switch.

Ford Super Duty (1999-2016) :: 2005 F250 - Multiple Misfiring Codes / Stumbling When Come To A Stop
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 ?

Ford Super Duty (1999-2016) :: 2000 F250 Engine Overheating / Low Power And Sputters
I just bought this truck for a pretty good price it has 225000 on it the engine was over heating. The guy put new rad, new water pump, new fan clutch, and a new heater core with thermostat. The truck still over heated so I pulled the thermostat to see what happens and the truck over heats even faster. All this happens while driving regardless of ac on or off. I got a motor and put a motor in it with all new pump and thermostat. I put new coolant in and flush radiator. I cut a hole in the cat to see if the cat was plugged for the truck seems to have low power and sputters. With in 1mile the truck over heated dumping all the coolant out of the system which the truck did as well before. Will the diesel rad work in this truck I have a diesel one I can put in since its a bigger rad?

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?
