Ford Super Duty (1999-2016) :: Running Rough - Check Engine Light Came On And Got Codes P0171 And P0174
My 1999 F350 SD V10 that would crank but not start. I ended up checking numerous things because before it decided to truly stop running, it would run rough for a time and then be fine. The check Engine Light came on and I got the codes P0171 & P0174. Well, I bought MAF Cleaner and took the air cleaner housing off, disassembled it and thoroughly cleaned the sensor and replaced the air cleaner. I continued to get those same error codes, but before I could go any further, the truck totally died. It sat for nearly 2 months with the bed in the air as I had decided to lift the bed to check the fuel pump vs. drop the tank.
Fast forward a bit and I have since replaced the fuel pump and put $40 of Premium Gas along with Royal Purple Fuel Treatment in the tank because I figured things got stirred up and could use a bit of cleaning. I do not drive much, and during the first few trips, it ran perfectly. Then today, it started again with the rough running and trying to die if I let it idle. If I pushed on the gas, it would completely smooth out. If this were a carbureted engine, I would think the low idle was set too low, but since it is not, I am guessing it is one or more of the sensor/s that is/are causing the issue.
I am disabled and can’t play parts swap until I hit on the right part, so I was hoping that I might get some guidance here to narrow things down to the most probably causes so that I won’t go broke changing things until I hit the “right one”. The truck has 153,000 miles on it and I had bought it from a retired couple who used it to pull their 5th wheel travel trailer, so it had mostly highway miles on it. It was immaculate when I bought it and ran perfectly, needing only normal maintenance (oil changes, etc.) over the past 12 years that I have owned it. In those 12 years, I have put about 60,000 miles on it.
Ford Super Duty (1999-2016) :: 2005 F250 - Running Really Rough When Engine Not Fully Warmed Up - Glow Plug Codes
2005 F250 6.0L ... My truck is running really rough when the engine isn't all the way quite warmed up. once the truck is fully warmed up to normal running temp it runs good. I am getting four engine codes. P0672, P0673, P0674, P0676 These codes say 2,3,4, and 6 glow plugs have a open circuit. Can this be the cause of my problem?

Have a 2006 F350 5.4l that is mainly used as a plow truck. I drive it at least once a week when not plowing just to make sure it runs ok, etc. Only put on about 2,500 miles per year. Keep it in good repair - not by me, but by the dealer or mechanics.
Problem - last two times I started it, it started ok but runs real rough for about ten seconds. Sounds like the engine is going to die. After about ten seconds, it "catches" and runs normal. Have no problems when driving it. If I restart it, it doesn't do this, so it seems to only happen when the engine is cold.
Battery was brand new back in Sept. All plugs were replaced maybe 3 years ago, as was the cat converter and muffler. Run non-ethanol fuel. What might be causing it before I bring it in.
Ford Super Duty (1999-2016) :: 2006 F350 - Hesitated And Tow Haul Started Flashing - Multiple Codes?
I have a 2006 F350 SRW 4WD 6.0 with 127000 miles on it. A couple of weeks ago it, pulling out of my driveway, it hesitated and tow haul started flashing. I had codes pulled and it showed P1780, P0751, and P2700. After turning off, codes were gone and tow haul off. Ran fine since then every day. Yesterday while going about 50 mph it started acting like it was in neutral (revving up), nothing happened when mashing the accelerator. Coasted to a driveway and truck would not move, only sounded like it was in neutral.

Ok just bought this truck ran fine. Put a sct tuner on that the truck came with and some how got the egr turned on. It had a egr delete so it was smoking and finally found it out that it had turned on but fixed it. Now we have another problem, it will start up and run fine and about 45 seconds it will start running rough and go into a limp mode. It will run rough and starts to die slowly and when it starts to die there is no throttle at all.

Recently, the truck started an issue. its an every once in awhile thing but has been doing it more recently.

2007 f350. About 2 weeks ago my truck started smoking really bad, and I took it in to have it diagnosed. It was 4 injectors that were bad, so I had them replace all 8 and also install a bullet proof oil cooler. From the moment I got the truck back, it did not seem to idle as well as it used to, and over the next week, it began to blow a good amount of white smoke and run very rough.
But the weird thing is when I took it back to the shop to have it diagnosed, the minute I pulled into their driveway, it ran perfect, and they were unable to pull up anything. The next morning, I started my truck for work and as I drove down the street, the truck ran extremely rough, and seemed to be running in 2 cylinders. I shut the truck down, restarted it and it ran a little better, as I limped it back to the shop.

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.
Ford Super Duty (1999-2016) :: Running Rough - Chugging Just Off Idle?
V-10 running rough at idle, chugging. a problem has developed with my 2004 E-350 V- 10 after having a new fuel filter installed and the induction service done . Picked it up from a local shop and it was running rough after bringing it in when running great! I figured maybe it fouled a plug or something so I drove it home but it didn't improve so I brought it back and had new plugs installed. It is still running rough and wanting to almost stall when accelerating from a stop and the shop cant figure it out , not showing any codes.
I'm thinking maybe they caused some type of vacuum leak that is so far undetected. The killer is it came to the shop running great !!
No other problems with the vehicle, I drive it every day and have owned since new. 278,000 on it now and it has been the best vehicle I have ever owned.
Ford Super Duty (1999-2016) :: 2003 F250 5.4 4WD - Running Rough?
I bought it and changed the fuel filter and it was dirty. Then ran a tank of gas with seafoam and then with lucas fuel injector cleaner. Still nothing. It idles like its missing and as long as you are light on the pedal it revs up fine but if you're heavy on the throttle its. Its has no codes that's why I haven't replaced the coil packs and plugs but they have been ordered. I just thought there would be an engine code if any of the coils or plugs were bad. Looked for a vacuum leak but couldn't find any. The donut gasket on the pass side is bad would that cause it to run shifty with no code.

I bought a 1999 f350 v10 about a month ago took it on a 1200 mile trip from Arizona to Kansas. Truck ran great till I got Kansas. The truck started to lope after I got fuel at a fuel station. Did not get any check engine light on. I check for vacuum leaks did not find any. I change all the coil packs, spark plugs, IAC valve and fuel filter. Clean the intake and put sea foam in the fuel tank and the truck still idles rough. Change the egr vavle. Truck ran great till I got 10 miles down the road then the truck started to lope again. So I'm getting really frustrated over this truck.

2001 V10- F250.. Runs rough- had the computer put on it and was coming up with P0174 codes (I think that is right)- In any case I replaced the Mass air flow sensor- checked for any vacuum leaks visually- I did not see anything obvious.... still runs like crap.... smells like gas when idling.... anything else I can check??? The check engine light went off finally (probably due to the MAF)- but it's driving me nuts- Any hoses I have not located I need to check?
