Ford Super Duty (1999-2016) :: No Power / Going Uphill Is Rough / Gas Engine Loud
Apr 12, 2016
I had a leaking coolant crossover so had to remove that and replace it with a new one. In doing so i removed the air assembly, throttle body, fuel injectors, and Spark plug coils. I reassembled everything, no more leaks but now my GAS engine sounds like a school bus. I've lost power, going up hill is rough, once i hit 40mph my car starts to shake a little bit but when I am on a straight away it will sometimes drive normal and sometimes go back to driving slowly. it also idles rough.

I bought 08 6.4 113000 on it 4x4 lariet drove 300 miles home. No problem 2 days later runs fine for 45 minutes than loses power and sputters up hills starts no problem every morning every time wait awhile sometimes runs fine was on e when test drove canged both fuel filters oil and drained 8 quarts tranny fluid and replaced it. When problematic rpms wont go over 2 turbo psi seems high seems in sync with rpms dropped...

While driving up hill at 60mph the truck lost power. Rpm jumped up as to change gears as it hit 55mph. Still losing power until it shut off. I tried to restart and just got a click from the solenoid. No engine codes whatsoever. Battery had 12.1 volts but when turning the key to start in getting 8 volts. Had it towed home. Today I swapped batteries with my other truck and same click noise from solenoid. All lights, radio, ect still work. Where should I start? Alternator, fuses...?? 2008 f250 5.4 ...

My truck has been broke down for a few months and I just got it started a few days ago my alternator was bad so I replaced it yesterday I also replaced the map sensor now I have a hypertech installed in it and showing a Wastegate fail error code and anyways my truck only from a dead stop acts real sluggish and 3 times in a row when I go up a fairly steep hill it will almost instantly die just go and then it doesn't want to start for a while after I roll it back on level ground now I can back up a hill and no problem its only when im heading uphill its really weird

I have a 2004 PSD with 85k miles. The engine fan is all of a sudden loud. You can clearly hear the fan pushing air and it's noise is relative to the engine RPM. I've had this truck since it was brand new and have never heard the fan blades unless I had my head in the engine compartment. Is the fan supposed to turn relative to the engine RPM or is there something wrong? Either way it's now all of a sudden super loud.

I have a 2005 F350 SD with 217K. It's got a Magnaflow aftermarket exhaust and newer OEM turbo. When I'm driving uphill and around 1800 RPM or higher, the engine makes this weird ratcheting sound when I let off the gas. It almost sounds like air is backflowing somewhere. It doesn't do it on level streets or downhills or when I'm below about 1500 RPM. The sound is not a metal on metal type sounds. It literally sounds like high pressure air backflowing somewhere or not being discharged properly. Also, I bought the truck used a couple months ago. So I'm not sure of all of the aftermarket upgrades done to the engine.

I have a 2000 F250, SuperCab, 5.4 triton, 100,000 miles. It's been a great truck - got it at 63,000 miles. Once engine warms up, it has rough idle, and shift rough. I can give it gas to RPMs up and it smooths out some but is low on power. If this was my 76 F150, I would guess the vacuum hose off the intake manifold to the transmission came loose.

I've got a 2003 6.0 that's got a rough idle and low power situation. Doesn't matter hot or cold it has a hard start issue but when it finally starts it has a rough idle, sometimes it has low power on take off but not always. FICM has 48.8 volts coming out, exhaust just had a new y-pipe (had a cracked bellow) absolutely no smoke coming out. When I drive it hard it's like a rocket no rough spots just did oil with filters and fuel filters, blue spring upgrade, and cleaned out the turbo.

Last night, I left it running while unloading a trailer and come back to notice it was idling abnormal. I jumped in it and tried to move it and there was a noticeable loss of power. I unhooked the trailer and tried to get it home. I only made it 1/2 mile down the road when it started spitting and sputtering (surging ever now and then) to a level that it died completely. I was able to start it back and get it out of the road but had to be pulled into a drive. It got to a point it wouldn't start back at all.
Today it started up however still had a rough idle and really has no power to speak of. The more I messed with it the less power it seem to have.
I have searched the forums and tried these things:
1) Checked the oil and noticed it was on the low end of the operating range. I put some in it to put it back to normal.
2) Disconnected the ICP
3) Changed the crankshaft position sensor
4) I dumped the fuel bowl after it completely died (in case it had any water in the fuel bowl).
The fuel filter was just changed 2 weeks ago. The fuel pump seems to be operating correctly (or it at least refilled the bowl) and started again with a very rough idle.
It doesn't have a engine light on nor do I have anything to read any codes it may be showing.

I drive a 2000 F250 5.4L. Currently has about 168,000 miles on it. I changed the oil the other day and cleaned the air filter. I used what I usually use on the oil change which has never been a problem. But this is first time to clean the K&N filter. A day or so later my engine is making a loud air rushing noise. Under throttle the engine compartment sounds like a wind tunnel. At 3500ish rpms it makes a harsh whistle noise. The air rushing noise doesn't go away once its warmed up or after the engine has been cool. Noise didn't go away with the filter being taken off either.
Could all of this be caused by cleaning and not using k&n air filter oil (but rather WD40 upon Dad's suggestion)? Or is there something else going on?

Last few months my 08 F250 has been slow going up hills. The fluid checks out ok and it shifts fine.
It just seems to take forever to get up hills. Has 124K....
Also has a huge hissing noise thats RPM dependent on the passenger side. Will make the sound in neutral just revving.

For the first time while towing a bumper pull trailer, started getting a very strong burning smell, only while going up decent size hills. After the climb, smell goes away. Kind of smells like burning rubber or wiring, but that should be constant and not just while up hill.
Checked tranny fluid and it didn't look burnt or low and never saw visible smoke. Have seen this discussed before but with no definitive conclusions. Truck has 150K on it and has long ago lost most of its towing power and the hills also drop the speed to around 45mph from 70 when I hit the big ones.

I have a 2001 excursion 7.3 4x4 with the 6.0L trans cooler. It is over heating when heavy, uphill towing is under way. I am guessing that my computer has been reprogramed at some point and more fuel is being injected than the radiator is designed to cool. I know my trans cooler is clean. I have tried cleaning the radiator and intercooler with a garden hose. I am considering a hood scoop or some sort of vents in the hood. When it over heats I turn on the heater and open the hood and the engine temps drop in just a few minutes so I believe that the engine needs more cooling or I need to slow down a bit on hills. Any other cheap fixes to get more air in to cool things under the hood more?

We have a 2008 f250 super duty with the 5.4 triton well ever since I replaced the power steering pump its been running raggedly, it idles rough and when i get up to 50, 55, 60 the check engine light comes on i put a diagnostic reader on it and said something along the lines of ECU bank 1 an Bank 2. What that is and I've been a mechanic for almost 3 years.

Lately my 2001 F250 5.4 engine is running rough when I am accelerating or keeping it certain speed. It feels like it is jerking. Like if the truck lost power for a second. This will go on for few minutes. Where to start to trouble shoot.

I have a 2001 7.3 ford the seal in the turbo went and oil went in the exhaust. lots of oil like 10 quarts. I had a rebuilt turbo installed ran great for 2 weeks then one day out of the blue started idling rough and then downward from there no power stalling etc I have my super chip scanner it read dtcs of 1249 478 1211 and 238. Is it possible the muffler is plugged with oil? or is it and ipr? 193000 miles....

I have a 2005 f250 with a 5.4 3v. I bought the truck with a cracked passenger side exhaust manifold about a year ago. We'll here recently the crack got worse and was giving the code P0171, so I had a shop replace it. I picked the truck up and not even a mile down the road it started idling terrible at lights and had very poor acceleration. And it gave me P0174 this time. It's only gotten worse now it's reading P0172, P0174,P0161, and P1489. I've replaced the spark plugs, MAF sensor, both vct solenoid, an the upstream o2 sensor on the passenger side. I also know I don't have any intake or vacuum leaks, I've had a shop check and so have I. It's starting to get expensive just replacing stuff. So, maybe I have a clogged catalytic converter ?

2005 250 5-speed total oil pressure loss ... At 110k mechanic diagnosed failing phasers from noise, rough idle, loss of power under 1k rpm. (Crew cab long box xl bought new for $25k)(first 100k were from carpenters (hard miles) so this truck is barebones and usefulness is much higher than cash value). Truck has 146k
All symptoms typically disappear over 1k rpm so I have limited idle time and manipulated engine speed to try and maintain 1000-1200 and all has been well for past 36k miles. Today noise (valve clatter?) persisted at all rpm and during a scramble to get off the highway all oil pressure was lost (I'm aware that pressure gauge on dash is not 100% reliable). After total pressure loss I cut engine and called tow truck. Out of curiosity, I actuated ignition and motor cranked maybe two rotations, and then appeared seized. After about 45 min waiting for tow I went back to disengage 4wd and take my rifles and skis out of truck. At this time I actuated ignition again and engine fired and ran as it had for past 36k miles. I drove about one mile constantly watching oil pressure gauge, then noise returned followed by instant drop from normal to 0 pressure (dash gauge) I immediately shut of engine.
I am a mechanical engineer, but not a mechanic. I am familiar with the cam phaser system and I understand that their operation is directly related to oil pressure. Today's temp was under 0'F. I have a very skilled mechanic who works for around 30-40% of cost of licensed shop and I know his skills to be on par.

Need this software that would be willing to run a diagnostic on my truck? I replaced all the glow plugs a year ago and the relay a month ago. It idles really rough when it's cold (first start of the day with outside temps even at 90 degrees). It has no power for about 10 minutes. Sounds like an old John Deere 2 cylinder tractor for a few minutes. I have 370K miles on it. After it warms up it runs good. Plugging it in doesn't make a difference. There is no smoke while it is warming up. I have noticed when I accelerate quickly, it blows black smoke (not heavy but when following it you see and smell it).

I bought my F-250 Super Duty 6.0 last October, and I am extremely happy with it comparing to my former '03 Dodge 2500 TD. The Ford drives so much better!
There is only one problem I have with it. Without pulling it shifts nice and has lots of power. A Month ago I bought a fifth wheel trailer and I hardly notice it behind the truck, also it doesn't use more diesel pulling. However going uphill the transmission seems to slip, and I can hear (sounds like) a fan running loud? I loose speed.
All the temperature gauges stay normal, no difference. It starts to pull worse. I replaced de tranny filters, inside and the outside one. Also I did put the correct transmission fluid in there, no difference. Almost no grindings in the oilpan/magnet.
I looked on many sites, but cannot find anything on this. Personally I think it's the torque converter? My final step would be to have the transmission rebuild, with the best parts available, (close to WA, ID, MO)...

1999 F350 7.3 Super Duty surges when going uphill with a load. The only time we drive it is when towing the horse trailer - also has a camper on.
The truck doesn't physically surge, just the RPM gauge goes up and down and along with it a humming noise.
Also, What conditions should I engage the towing button on the end of the gear shift? I've heard several answers. Should it be engaged when towing or off?
