Ford Super Duty (1999-2016) :: Engine Will Start And Idle But Bogs Down And Stalls If Give It Gas
Nov 5, 2013
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.

I am having an issue with a Ford f250, 5.4L, granted this problem existed before and after new A/C compressor, dryer, evaporator, vent door switch, blower motor resistor, new evac and recharge, good pressures no leaks.........Now my problem is the truck runs perfect but when the ac engages at idle the engine bogs down and it seems the clutch is constantly engaging and disengaging........AC blows cold, no issues there, does this sound like an IAC valve problem????

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.

I recently purchased this 2003 F350 DRW with the 7.3L, automatic trans. Truck has 140k on it. Three times now while the truck has been idling, the engine just died. The first time was a couple of weeks ago when I was pulling out of the driveway. Then again yesterday twice, once while just sitting at a stop sign. Each time it has started right up and ran fine.What is going on here?

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.

I just bought this 99 f250 7.3 Powerstroke last week.. drove it all week fine, I car pool with a family member to work and asked his girlfriend to plug my truck in for me, well she didn't and it had stalled on the way home one morning but started up after cranking a few times i thought nothing of it. Drove it a little bit that day and it was fine, while I let it idle in my drive way as I prepared to go work it started running really rough then died. It took a long time to start again..now it's happening all the time. I changed the fuel filter and someones telling me there's air in the lines..

The 19.5" wheels are not an option on the 2013 F-450, unless you order a Chassis Cab. I'm certain many have made this change. My question is can the dealership make the necessary changes so the speedometer correctly measures the vehicle speed?

I bought the 2005 F250 6.0 Turbo Diesel with 67,000 miles on it last March. It has given me gave me absolutely no problems until now. In the last 2 weeks I have had it plugged in when it was below 32 degrees outside. Otherwise, I just remote started it every morning and let it run for 20 minutes before I left. In the last 2 weeks, I have noticed the same problem whether it is morning, afternoon, or evening and it happens at different times. I will be at a standstill at a stop light, stop sign, or parked in my driveway when this occurs. Sometimes, and like I said, "sometimes", it will hesitate when I give it throttle. It will quickly respond after maybe a second, but the hesitation is still there. It only does this on occasion!
I work for a Lucas Oil distributor, so in the winter I ran the "extreme diesel conditioner" through it with a tank of diesel about every other week. I also used the fuel-injector cleaner at every fill up. On "ONE" occasion, and like I said, "ONE" occasion, when it hesitated at a stoplight, I looked in the rear view mirror, and noticed a short burst of white smoke, and then it took off. It has not done that since. I took the EGR off and cleaned it and it seemed okay until 2 days later, then the same hesitation came back, but like I said, at times!
I replaced the air filter and since then I have done nothing. I am now being told to check the coolant level in the resevoir. When I un-screwed the cap the cap, there was pressure in there and the fluid was about 1/4 inch low from the line. I was also told to check the filter on top of the block, but I have not gotten that far. Ford says it is the EGR cooler system! I have "NO" check engine lights!

I have a 2006 6.0. It's hard to put into to drive and for you to get it moving you have to just about floor it. The tow haul light is flashing but my bullydog won't pull the codes. It stops moving after like 30 to 40 ft after you got it moving and acts like it's in natural. If you turn it off and back on it sometimes will move another 30 to 40 ft sometimes. It also sometimes if you put it in reverse won't let you give it gas. Like you can push the pedal but the rpms won't climb for this reason I'm thinking something to with a solenoid or fuse or something along those lines and also because if you restart it will move again. I don't know much about transmission. I'm taking it to a shop tomorrow for them to try and read the codes. If they say the transmission is toast i already located another one 2 hours away to swap in which I'll do myself to avoid the high cost of the shop which also I'll look to yall for guidance. I drained some of the transmission fluid and didn't see any metal flakes. Should I pull the pan as well and look if nothing is coming out in the trans fluid ?

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.

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.

Simple enough the truck starts then after about 30 seconds it bogs down and dies. I am getting these codes.
705 Transmission Range Sensor Out of Position
708 Transmission Range Sensor Circuit High Input
720 Output Speed Sensor Insufficient Input
743 Torque Converter Clutch Circuit
745 Pressure Control Solenoid Malfunction
1747 Electronic Pressure Control Solenoid A- Short Circuit
Sounds to me like the converter it locked up. What do you think? Its a 5.4L

When I "step on it" on the freeway or even a moderately inclined freeway ramp, it bogs down and actually takes a few moments to cover. Sometimes will leave me crawling at about 20mph for a few minutes. Engine revs just fine in neutral. If I very slowly build up speed I can cruise at 75mph, but forget passing. Also, this came along at the same time a severe shaking/shuddering spell started. Not always, but often it is shaking the entire body and certainly through the steering wheel. Was so bad the first time I stopped to see if I had a flat. Usually lasts until I slow way down and ease my speed back up. Had the front end steering structure replaced about two years ago, so I don't think it is that. What is the cause of the bog down and could the shaking be related? This truck sits for 2-3 weeks at a time and then I drive for about 50 miles and park it again. Can Michigan gasoline go bad that quickly?

I have a 2000 ranger 4.0l 4x4 automatic transmission 5r55e. When I put it in drive I don't have any problems except in do it starts jerking when I give gas. When I put it in reverse I can move but as soon as I give gas it stalls the engine tranny was sitting in another truck swapped it with mine I changed the filter and 5 1/2 quart of oil.
I when to a transmission shop plugged it inn no codes and he said he would changes all solenoid and valve body gasket but he's not sure what is the problem. So I started to take out valve body and notice the oil is darkish red and was wondering if it was normal or not and if I'm taking that valve body out for nothing or should still go ahead ...

My truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.

Just changed the oil in my 6.0 and I'm sitting here looking at my tuner and is telling me my idle rpms are about 770.
Before I changed my oil it idled around 750.
It's running fine, I was just wondering why it changed? More pressure to the injectors with the newer oil?

06 F250 6.0 with only 65,xxx miles on it. This has happened twice and both times the engine was warm and had been cut off for less than 10 min.. When I tried to crank it back up it stumbled and idle roughly then cut off. After several attempts to re-crank it still would idle rough and I tried to give it fuel but no change, even with pedal fully depressed. Then it would die.
After sitting a few minutes it starts normal. Both times I didn't have my obd2 adapter for my torque pro. The last time it happened I went home and hooked it up and got no codes. Everything looked fine. What could it be, where should I start looking. Batteries are1.5 years old. Oil, oil filter, and both fuel filter changed about 1000 miles back. I have had the truck for 1.5 years and the oil has been changed twice.
