Ford Super Duty (1999-2016) :: Rough Idle And Stalls But Runs Fine At Higher RPMs - No Brakes
Let me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.

2004 F250 V10, runs good until it warms up whether it's hot or cold outside. While on freeway, it really shakes while cruising, but of you get in the gas enough for a kick down, seems to be pretty smooth. I've changed the coils, and 9 plugs (one wouldn't budge, but the others I took out looked fine) to no effect. Where else should I look? Also, no CEL, and no codes, which seems odd as bad as it feels...

This is my first diesel but my 4th Ford truck. The truck currently has 4000 miles on it. My first incident started at 500 miles when my windshield gasket or lack/loss of silicone on the upper gasket decided to go. This caused a tornado in my cab at 6 am blowing coffee out of my cup and literally atomizing it all over myself pretty much LMFAO. It sounded like a helicopter attack at 40mph when it went. Ended up being towed to the dealer for repair. At around 2k miles the truck started too stink, like exhaust and coolant maybe. I'm thinking it's the DEF or the left overs from a regen cycle (newbie). At 4K miles, it's getting worse. The cab almost feels like deicing in the plane on the runway, nothing but fumes. It literally blows in through my HVAC vents straight into the cab. I'm glad I own the company because I'd be afraid of getting a drug test when I got too work. Instant red eyes. It is not as bad while driving but starts up again at red lights etc. It's a handful of times a week it does this. Things I've checked, water separator, 0 water in diesel. I've tried different gas stations and different DEF brands. Nothing makes it better or worse. I've read that I'm not alone, God speeds too us skunk trucks.

My truck started running poorly with an intermittent miss about 6000 miles ago. The miss gets more consistent when the tank is below 1/2. Fill it up and the miss goes away. No codes, shop that does a lot of V10 camper work could not figure it out.
My guess is that the fuel pump is going out and it overheats when the tank is low. The problem is getting progressively worse. Now it misses slightly with 3/4 tank and even a full tank sometimes.
Plugs have been changed, fuel filter has been changed, and the shop found 3 COPs that were bad before all this new intermittent miss started. The truck runs ok at wide open throttle.
Am I just nursing a bad fuel pump that will leave me standed soon? Truck has 170,000 mile with original fuel pump.
Ford Super Duty (1999-2016) :: 2007 F250 Running Rough / Missing On Cold Start
So, I have a 2007 f250 with the 6.0. When she's cold she starts fine but runs rough like she has a miss. When she warms up the miss goes away and it runs pretty good. But if I shut it off it won't start for about an hour or so.
ICP sensor has been replaced.
FICM is putting out 50v
Ford Super Duty (1999-2016) :: 2006 5.4l Runs Rough For About 10 Seconds When Started
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.

I have a 2000 F-250 Diesel that has started acting strangely. It starts and runs well, but every once in a while the peddle just stops working. Might be a second or so and then the RPM will go up. Or you may be running down the road and all of the sudden it just stops acting like it is getting enough fuel. Same thing it might last a second or so. Sometimes it might happen 4-5 times in a row over a few minutes and might not happen again for a day. Truck does not stall when this happens. It just does not go like it should.

I have a 03 250 5.4 with 160k. I just recently replaced #4&3 coil packs. Truck was running great again. Then a few days later the truck was running extremely rough and white smoke from the exhaust. I noticed the pcv valve was not all the way in(pretty much out) put it back in and ran fine for two days now running rough every now and then and the pcv valve is making a vibrating noise but stops if I pinch it slightly. I did replace the plugs a year ago.
View 14 RepliesFord Super Duty (1999-2016) :: 2014 F250 6.2L Gas Engine Stalls At Highway Speeds
2014 F250 SuperDuty 6.2L gasser, x-cab long bed work truck. 105k miles, original owner, 1 driver, mostly highway miles, well maintained and super clean truck.
First issue occurred at 83k miles, Aug 2016. Warm summer day climbing I-70 in CO, slightly loaded, and just entered the Eisenhower tunnel (11,150' altitude). Lost power, no RPMs - not running, I put it in N and rolled as far as I could. Hazards on and no-where to pull over, hugging the wall and blocking one lane. Power OK - will crank, no fire. 1/3 tank on the fuel gauge and >100 miles distance to empty on the trip computer. Tunnel rescue shut down traffic and pushed me out into the daylight.
After waiting an hour to fill our paper work for disabling the interstate tunnel I returned to the truck which quickly started. No symptoms, no lights, no codes. Topped off the fuel tank after a easy 15 mile drive downhill. Drove another 800 miles symptom free to my destination and checked it in at the dealer. At this time a check engine light had finally illuminated - PO420. I shared the story of stalling out at highway speeds with the Service Writer. Dealer replaced the cats, confirmed fuel pressure OK, computer condition OK, serviced the trans (at my request).
No symptoms reoccurred during the next 20k miles until last weekend. 105k on the OD now. Heading to Flagstaff, AZ on I-40 in similar conditions. Hot, AC running, climbing in elevation, slightly loaded, running on the bottom 1/3 of the fuel tank... Died while cruising at 79 mph. Well, at least this time I wasn't in a tunnel and had a shoulder to pull off on. Deja-Vu - full power, radio on, no engine lights, gauges normal, fuel reads over 1/4 tank, >100 miles till empty on the trip computer - won't start. Cranks, but no fire. Some sputtering during start attempts must have triggered the next trouble code.
Opened the hood, removed the gas cap, let it vent and cool for about 30-40 mins while I took a walk. Returned to the truck which easily started and let me drive to the next fuel station, 30 miles away. This time the check engine light stayed illuminated. It took 24 gals of fuel. Drove 3 more hours and almost 200 miles without symptoms - check engine light still illuminated keeping me curious and fully alert along the way.
Got the codes pulled at a parts store that was open on Sunday. PO300 & PO301. Random misfires and cylinder 1 misfires. Sounds consistent with poor fuel supply? Spent the rest of the day searching forums for any clue to this highway stalling. All I came up with was to clear the computer - disconnect battery, turn lights on, wait 15 mins, reconnect battery, start engine, apply brake, drive, etc. This and another full tank of gas gave me enough courage to set out on my trip home.
Next occurrence was just outside of Santa Fe, NM. Similar conditions again: Hot day, AC kicking, Interstate travelling about 80mph, slightly loaded, climbing in elevation, fuel tank just below half - stalled out. Repeat previous learned routine. Open hood, vent gas cap, walk it off for 30 mins, return to truck, start it up. Drive to next town and top off with fuel about 30 miles away - only took 16 gals! Made it home 4 hours later without stopping. No repeat symptoms, no check engine lights.
The next day a code - PO420. Catalytic efficiency below threshold.
Quick recap:
6.2L gas engine stalling at hwy speeds.
Cruising between 65-80mph
-Interstate travel - no stops between last fillup and stall.
-Warm weather, AC on
-Running on bottom ~1/2 tank
-climbing in elevation, slightly loaded
To clarify: slightly loaded - no trailer, maybe 1,500 lbs bed cargo, mostly wind drag. The most I have pumped into the fuel tank is 29-30 gals or so. I assume I have the 34 or 35 gal tank. Never seen the calculated "distance to empty" below 40 miles.
Ford Super Duty (1999-2016) :: Truck Won't Start But When It Does, Runs Perfect
So I just bought my first car, a 2003 F250 Super Duty with a 5.4 V8 gas engine with 150,000 miles that I will be using to tow my horse trailer. It has some things I need to fix. The main issue is that it wont start.
When I first went to look at it I tried jumping it, as the battery was dead and I still couldn't start it, though it was turning over. The previous owner then tried jumping it the next day, got it started and met me half way where I bought the truck. Turned it off where we met and it started right up again and I drove it home. It sat in my driveway overnight and then wouldn't start the next day, though it is turning over like before.
The battery is only a month old. There is another sensor issue where they had to disconnect the dash or the truck would randomly stop running. I believe it's the speed sensor? I received the repair reports from the dealer saying "code B1352 in memory for ignition key fault" and they removed an aftermarket remote start. "four U1027 and other U codes found, replaced crankshaft sensor".
Ford Super Duty (1999-2016) :: Remote Start A/C Fan Runs Lowest?
I bought a 2016 F-250 Lariat, Crew Cab, Short Bed, 4X4, 6.2 a couple weeks ago. One thing I had to have was remote start. My truck was not manufactured with remote start so the dealer installed the Ford 1 way remote start system. The system works fine however the air conditioning fan runs on the lowest speed when remote starting until I put my key in the ignition at which time it reverts back to wherever it was set when I shut the truck down. The whole point of the remote start for me is to get a head start on the truck cooling off but with the fan on low when remote starting it defeats the purpose. How I can change the setting so that when I remote start the fan runs on high? Dealer is clueless and the settings in the truck only allow to turn the system on and off and run time duration.

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) :: 2008 F250 - Very Rough Ride
My 2008 F250 Super Duty is riding very, very rough. I put in new heavy duty Bilstien shocks 2 or 3 years ago, and I would think they would last longer than this.
Are they any other causes I can look at to see what is causing this truck to ride rough?
