Ford Super Duty (1999-2016) :: Truck Lost Acceleration When Got Up To About 35 MPH
Feb 21, 2017
I drive a 2000 F250 XL Super Cab LB 2WD 7.3 Powerstroke. i drive like a grandpa. No rompin on the accelerator or anything. I was leaving the house got up to about 35mph and the truck lost acceleration. Motor still running fine. I coasted onto a side road. Put it in park, killed it, started it again and same thing. Will not go into drive at all. However will go into reverse just fine and accelerate in reverse. Desperately wanting my favorite means of transportation back!

My 2003 6.0 truck lost most of its power. It has the SCT programmer. It used to run great it would roll coal really well then it slowly started to run worse. Now it runs really sluggish especially when its cold. IT takes forever to warm up. On the freeway when ur going a constant speed it bucks and jerks a lot. It won't roll coal anymore and just runs like crap. A mechanic said I had 3 bad injectors. But I don't believe it.

All week the truck was acting like the clutch was slight depressed when first taking off and then today i was driving and the underside of truck started smoking like crazy and slowly lost all the gears could put it in any gear and nothing just was acting like it was being revved. does this mean clutch is bad?

Question, my truck started to have a miss under normal acceleration, when I really get on it, it clears up? I also noticed a bad sulfer smell at idle. Im thinking the cat is possibly plugged? Truck had 172000ish on it, and the cat is original. I did do a big tune up this past fall, new plugs, coil packs, air and fuel filter. Should I put a new cat on it? And a new oxygen sensor?

I am updating my efforts at diagnosing this.... The antifreeze never seemed to lose any fluid..... The truck lost all oil pressure and after draining the oil, It seemed to have chunks of ice in the pan ! (not anti-freeze then right ? ) The oil was totally slimmed up like a milk shake...... I pulled the oil cooler and took it to a radiator shop who pressure tested it and said no good news>>> No leaks >>> no easy fix..... Is there any way snow or rain water can get past the intake manifold and into the valley? I got a snap-on SVT cooling system pressure tester. The system holds 10 lbs for man hour without loosing a pound, while running under pressure the gauge does not fluctuate (The truck runs GREAT sounds like a nascar). I just did a valve and chain job 2 seasons ago (think I do good work like I give a rip about my own stuff )I put the right stuff gasket sealer around all the water jacket port on the head gasket....... Is there any other way water can get in this thing ? I am going to change the oil again,add sea foam and start driving it...

Ive read here that our trucks can lose all of their AC fan speeds except High - mine has done that as well. However, even High on my truck doesn't blow much air. I looked behind the glove box for an interior air filter, thinking it might be clogged but couldn't find one. What could be stopping my blower from putting out?

I have an 05 F-250 with the 5.4 liter motor, 4" lift, 35" tires 4x4. I have not had any problems with the truck and have 110,000 miles on it. the only thing I even did to it was replace an alternator. Recently it seems to have lost power.
I use the truck mainly for hauling my smaller horse trailer which is roughly 7500 fully loaded but most times i haul it at about 5500lbs.
I also have a 2003 7.3 which we pull at 20,000lbs no problem

I was driving down the highway and the truck was in overdrive and under a load passing at about 20lbs boost and all of the sudden I lost all power, felt truck shake a little. The tow/haul light is flashing and got only one code P0730. The truck won't go into gear in either forward or reverse now, had it towed home and put a pressure gauge on it and found about 100psi at idle In neutral, in reverse and forward I got strange readings the pressure goes way up momentarily then down to 100psi, and increments back up to over 500 psi and seems to stay there but neither forward or reverse engage. I have no clue what could be wrong at this point. I am attaching a video .....

My 6.0 lost a bolt that holds the AC clutch and the clutch fell off. It's probably on some highway making people have flats. Is it possible to buy a replacement clutch and NOT remove the OEM pulley, just take the parts off the replacement clutch and put them on the old AC and existing pulley?

I don't know what is wrong with my truck. I don't know what this symptoms called, but It felt like it was missing a beat. The engine suddenly lost power for a second or two wile driving. It did this few times. Is it the engine or the transmission? No check engine light is on. 2001 F250 5.4 V8

I have a 99 F250 5.4l 4x4 Super Duty that just all of a sudden stopped going over 30mph. I was traveling down the highway at 70mph and all of a sudden the truck acted as if it were in neutral and started revving up. i let off the gas and the problem stopped. i went to pass someone and it occurred again. I slowed down to 65mph and a couple minutes later it did it again. I wasn't too far from home so i drove it there. By the time i got around the corner I had the truck in second gear to prevent me from going over 25mph. i allowed the truck to rest and then checked the transmission fluid and everything looked good. There was a slight squeak that had just started and appeared to be coming from the drive shaft. I am mechanically inclined but new to working on vehicles..

I have a 2011 f250 with the 6.2 liter gas engine. Lost power and the check engine light came on. I pulled the codes and it is a camshaft position sensor and 4 other codes for misfire on all cylinder for that bank. I can't find any info on where the sensor is located or how to replace it.

I have just replaced the EGR cooler, Oil Cooler, professional turbo reconditioning, both dummy plug's and stand-pipe's, blue spring, fuel filters, oil changed, cleaned the EGR valve and intake manifold. I am in the process of doing a coolant flush when my issue occurred. I was on the road for about 10 minutes when I lost power and started blowing black smoke. I have normal power till about 45 mph then nothing. I can baby the truck up to 55-60 and then nothing and the whole time blowing black smoke.
I stomp on the pedal with no power. I hear the whine of the turbo. The truck idles and sounds fine. My SCT showed my oil and coolant temps within 15 degrees. I opened the hood and saw soot all over the top of the engine from the compressor to the EGR valve and all in the valley from valve cover to valve cover; but more so on the driver side to FICM. I obviously didn't connect something properly. I am just about to remove the intake manifold and reinstall, but before I do just wanted some input.

So i was replacing my power steering box after the shaft broke on it and apparently i didn't have my steering wheel back to exact center. after putting everything back together and started to drive down the road a very thin flat wiring harness broke and got tangled around my steering column under the plastics of the column. I then lost my horn and my cruise control and i believe my airbag. I pulled the wiring harness out and it was very long with two white plugs on either end. I'm not sure what this part is called or where i would be able to buy another one. And if there's some kind of instructions on how or where this harness plugs into sense it was ripped out.

I have an 03 F250, 5.4, 4x4, with aprox. 130k miles. I recently had my exhaust manifolds replaced because 1 literally cracked in half. Ever since the replacement, I'm getting worse gas mileage! Im only getting aprox. 250 miles to a tank when before it was well over 325 (highway)...

I have a 'new-to-me' Ford F-550 with the vaunted 7.3 Powerstroke diesel engine. The truck only has 120k miles and ran great when I bought it. Last week it began acting up. While driving on the highway, it lost power, began running rough, and once I pulled over, it died.
After a few minutes, I tried re-starting the truck, it started, but had little to no power....I could get up to 30-35mph and then it would slow down and lost all power. I let the truck sit for about 20 minutes while I refilled the diesel tank, it started right up and drove normally for another 10-15 minutes and then the same thing happened again.
The truck sat for a day and then drove normally for two entire days. This morning, it began acting up. It is the same as before..... what to do with this type of issue?
There is not a check engine light lit (yes, it works). The diesel is from a good source that is not causing problems in anything else. The truck is otherwise strong.

I have a 2010 F250 with the V10 and 42000 miles. Lost*power*while pulling a trailer. Couldn't get over 30 mph. Tried turning back home and lost all*power*and would barely idle. Fuel filter good air filter good. Code P0300 came up. Towed it back to the house and then couldn't even get it to idle. Wouldn't throttle up past about 2800 rpm. Cleaned MAF sensor and nothing. Somewhere during all that P0174 code came up and misfire cylinder 10. Cleared codes and they haven't come back. Now when trying to crank, it barely turns over, yet battery is good. Opened air filter cover after getting it to start one time and there was some light smoke coming out. Also while barely keeping it running for a little bit, the catalytic converter on the driver side was fire hot and the other side I could grab with my hand.

So I was traveling thru the grapevine on the 5 Fwy and no problems. Made it to the top didn't over heat. Then all of a sudden it lost power. Pulled over and it stopped running. Won't start. Fuel is pumping, I took off the fuel filter and turned ignition on and it filled up.

Have power to both fuse boxes and battery is fully charged.
