Ford Super Duty (1999-2016) :: 1997 F350 - Engine Stalls Going Down The Road With No Warning

I have a 1997 f-350 crew cab 4x4 w/ off road package and 7.5 fuel muncher power package. My engine stalls going down the road w/ no warning. Sometimes it will start back up immediately, and other times not until i cycle the ignition 6 times or so.it seems to be getting worse as time goes by. Since it started i replaced tps, cap, rotor, plugs and wires. I also replaced fuel tank and pump and filter about 1.5 years ago. Some other issues to clear up, but concerned w/ current problem.

Ford Super Duty (1999-2016) :: Engine Will Start And Idle But Bogs Down And Stalls If Give It Gas

1999 Ford Triton V-10 engine, after changing Oxygen sensors, all vacuum hoses and Mass airflow sensor,(also replaced another sensor but can't think of the name of it right now) now I don't get the codes but engine will start and idle but if I give the engine gas it bogs down and stalls. Vehicle sat in my driveway for 3 months, I got it started and drove it once about 30 miles filled up my gas tank thinking gas could be stale, but now it will not run.

Ford Super Duty (1999-2016) :: 2002 F350 Stalling - Check Engine Light Came On And Truck Would Not Idle At All

I have a 2002 f350 5.4l that has stalling issues, first some back round. Last week I pulled up the a stop light and the truck stalled I figured it was a iced fuel line as it was very cold so I put a bottle of drygas in the tank. Evidently there was a lot of moister in there because as soon as I started the truck check engine light came on and truck would not idle at all. I got through that tank and am now on my second tank. It is better but the truck will still stall when stopped at light (has never stalled in park or on the road only while stopped in drive) the check engine also light went off halfway through the first tank. What next?

Ford Super Duty (1999-2016) :: 2001 F350 V10 Stalls But Fuel Pump Stays Running?

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

Ford Super Duty (1999-2016) :: Intermittent Stalls At Idle And Hard Start

As a follow up to my problem of intermittent stall and hard start, it is getting more pronounced. Now, every once in a while, it will start. Mostly it will not start.

This morning I connected an OBD2 meter with the key on and engine off. It told me that there are no DTC's. As I was attempting to run enhanced DTC's the code reader lost link with the computer. The connection icon was on but it lost the link. At one point, after several tries, I got the link back but it didn't last too long before it was lost again.

This is the same symptom that I have with running the engine. It will run and then shut off. After a hard start, it will start and run just fine and then shut off again.

My question is this. Can I still have power to the PCM and loose power to the processor? Is there a fuse or relay that could be causing this problem? If not, could the problem be a faulty PCM.

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.

Ford Super Duty (1999-2016) :: 2003 - Shakes - Stalls Out?

So I'm new to this, but heard that there a lot of great people on here that have tons of knowledge. So here goes. I have a 03 7.3 f250. I'm have trouble with the first initial 20 minutes of the truck starting. It starts fine but if I throw it drive and start to go it's shakes bad runs horrible and will sometimes stall out. If I let it idle for 15 to 20 minutes first and then drive it it runs perfect. I have replace the fuel filter, and air filter. The truck has roughly 125000 miles on it.

Ford Super Duty (1999-2016) :: 2013 F350 6.7L - High Idle At About 1000 RPM

New too my Ford, but anyway it's -10 Celsius. My trucks been idling for a few hours and probably will all day because of my job. Usually idles about 600rpm normally. So today the oil temp was about 80degrees Celsius. Then the truck idled up too about 1000rpm for a while. If I touch the gas it goes back to normal idle speed but then starts idling up again after 30 sec. What temp does the truck want too keep it at?

Ford Super Duty (1999-2016) :: F350 - Power Steering Loss At Idle

I have a 1999 f350 7.3 diesel. If I apply the brakes when I am not moving it is almost impossible to move the steering wheel. I have flushed power steering system. This problem has gotten worse over the corse of owning the truck for the last 10 years. Ball joints and u joints are good. Had to change power steering cooler a few years back, rusted out line, really got gradually from there.

Ford Super Duty (1999-2016) :: F350 V10 Rough Idle - Started To Lope After Getting Fuel

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.

Ford Super Duty (1999-2016) :: 2002 F350 7.3L - Rough Idle / Knocking / Loss Of Power

Alright, I have a 2002 f350 7.3 4x4 ext cab xlt with 300k miles. Bought in may 2016 with 260k miles and towards November started running rough and felt like a loss of power. Had a no start but a new gray cps fixed that issue. Running fine. About a week later started it up and it had a rough idle, felt like not all cylinders/injectors were working. Was "knocking" and a loss of power. I was in the army at the time and stationed in Georgia, took it to a local diesel shop in Georgia and they confirmed my icp sensor was bad and injector #1 , #5 #7 were bad. Work was busy and money was scarce so I left it as it is and was saving up to buy the new parts. Then one day approx a week after the visit to the shop, I started the truck up and it ran fine. No misfire no knock no rough idle, drove fine for about a month.

In December, I was on vacation in florida to see my parents, drove the truck down, ran fine. While on vacation one day in a Walmart parking lot the truck didn't start up. Couldn't fix any issues then so towed the truck to my parents house. Did more troubleshoot, replaced fuel filter, cps, ipr valve, icp sensor, glow plugs, glow plug relay, ebpv pedestal was replaced with a ebpv delete pedestal. All parts bought oem and/or from riffraff diesel. Still would not start up. So then I bought a refurbished IDM from eBay, oem and then the truck finally started up one day but running rough again like it used to, then it wouldn't start again. So then, I replaced the PCM with a reflashed/refurbished one off eBay and boom truck started up, still running rough but now it starts up every time.

Now, took all eight injectors out and replaced all the o rings. Cleaned them up and put them back in, truck still running rough. Injectors didn't appear damaged nor the wiring harness so now I bought three reman injectors from riffraff. And replaced those three bad injectors. One of them is not spitting oil out the oil spout on the injector.

My dad has worked on freightliner semi trucks for years and is fairly knowledgeable when it comes to diesels. However he did something very amateurish the other day. So two injectors were installed while we were still waiting on the third in the mail. He wanted to see how the engine reacts when that one bad injector was not in play, but instead of unplugging the injector under the valve cover, he cut the wire outside the valve cover to the injector. He stated it's not a big deal and he can solder the wires back together. But once he cut the wire, the truck sounded a lot stronger, still rough idle but definitely stronger. Before, you would be pedal to the floor and the truck barely moves forward but now the truck will lunge forward. A big difference in power.

Now today, third injector came, swapped them out and fired up truck. We didn't solder the wire yet just quick connect, same you would use to connect wires for a car stereo. The new injector was not spitting oil out the oil spout. Even at high rev and truck warmed up. Truck still runs better with that one injector unplugged.

Tomorrow we will troubleshoot if somehow there's wires that grounding out or burnt out somewhere but as of right now everything seems to be in order, the uvch are tight, and no signs of anything burnt.

Triple checked everything, still getting fuel pressure, still getting oil pressure what gives? I also replaced the MAP sensor. Fuel pump is fine, fuel gets to fuel bowl. The next thing I'm thinking is maybe the hpop but we have oil pressure so idk..

Ford Super Duty (1999-2016) :: 2004 F350 Making Fog Horn Pitched Howling Sound At Idle

I have a 2004 5.4 power f350 that makes a fog horn pitched howling sound at idle. First instinct was a pulley. Started it with belt off and its obviously something else because it still made noise. Traced it down to a resonating sound from the intake. Specifically the hose from the IAC to the air cleaner.

From some googling, i decided to change the IAC. No real change. So I took off the resonator tube and thoroughly cleaned it, took off the throttle body and cleaned it, took off the top snout part of the intake and cleaned that put in a new air cleaner (the glue was separating on the old one) and reset the battery. Still makes noise at least 85 percent as loud as when i started. Am I missing something?

Ford 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.
