Ford Super Duty (1999-2016) :: 2004 F250 Truck Not Running Strong / Hesitating When Step On Gas Pedal
Oct 25, 2016
I have a 2004 f250 6.8L and recently I've notice the trick not running strong. Is hesitating when i step on the gas pedal. For example, I am driving on the feeder road and fixing to get on the freeway ramp, well i have to spent a bit harder on has pedal to gain speed, but it seems its struggling and I can hear muffler making like a flapping noise. Also when I am going between 40-65mph and I spent on it, the tricks kind of jerks and vibrates. Feels like its coming from transmission. I let go and step on it again and it goes away. What to check??
Miles : 96k
Year: 2004
No Check Engine Light

My 2002 F-250 v-10 sat for over a month with me in the hospital for spinal reconstructive surgery. Battery was dead but has been charged and tested as good. The truck cranks strong but will not turnover. I am unable to do other diagnosis, what might be the problem.

Can get up to speed about 55-60 in my 2003 f250 6.0 4x4 truck and hit the brakes hard and the pedal gets hard almost like you cut the truck off and the truck doesn't stop well I can let off the pedal and hit it again hard and it works like it should. Also when it does this the power steering doesn't work. I was on an exit ramp and almost wrecked when I exited off the interstate I hit the brake pretty hard and couldn't steer I let off the brakes then hit them again and it worked fine and so did my steering. It would seem that the two are connected somehow. What's wrong?

Just got a 99 super duty and I have a very weird problem. When stopping i feel a very strong pulsing from the brake pedal. I assumed warped rotor. but the strange part is when I hit the brake the cab dome light comes on. How to locate this pulsating?

I am a trucker at heart and I like to add running lights to my running board / step bars. As far as installation of the lights, done it several times, no problem there. However in the past, I have just ran a wire back to the trailer plug and used a scotch lock / snap connector to feed the running board lights.
If I do the same on a 2012, will that cause havick with the computer? Most likely I will be running 7 lights, all 3/4" diameter LED style. If this isn't' the best solution, then where to get power for marker lights.

I have a 04 f250 with aprox 95k on it 5.4L I knew I was over mileage for a due oil change I haven't been driving it much it crossed my mind, as I am usually very adamant about changing fluids. I went to check my oil and only a smudge of oil on the dip stick. I know this is not good but the truck runs fine, no noises, no knocking, not a chatter from the valve train. Oil pressure was good everything seemed fine did I get lucky? I know it wasn't good I am not going to let that happen again everyone think I dodged the bullet?

I don't know whats up with my new truck, its a 04 f250 scsb, 4x4, 5.4l with 61k orig miles on it. Truck will stop on a dime, has NO pedal sinking, but it takes about 3/4 of the pedals travel to apply pressure to the pads and have the truck stop, sometimes if I push the pedal down then let up and push it again the pedal wont travel as far, I just flushed the system today, no air in the lines, is there a bleeder on the abs? truck has 4 wheel abs...

I'm having a problem with my 04 f250 6.0. I replaced my brakes rotors and calipers yesterday along with my fuel filters and after I took out my air filter to check it and put it back in my truck will no longer crank. When I put my key in the on position all of my lights and dings happen but I don't hear my fuel pump and when I go to turn it over I get nothing at all.

I have a 2004 SD with 5.4 that is running pretty rough both at idle and driving. Truck shakes a lot at lower rpms. I have a scan tool and had a misfire on cylinder 4 so I replaced the coil and the plug. Also replaced the idle air control valve. Plan on replacing O2 B1 S2. (One of my codes) even after replacing the coil and plug I'm still getting misfire detected from cylinder 4??? Other codes I had were misfire detected on he first 1000 revolutions. That hasn't come back though.

I have a 2004 f250 with a 5.4l and it won't start. I went to leave the store and went to start it and the truck started when I turned the ignition on not when I engaged the starter so I drove home anyway but there was what sounded like a spraying noise coming from underneath the truck all the way home the truck did die once on the way home but started right back up without me doing anything. Got home shut the truck off now it won't crank or anything all my lights and everything come on like normal just won't crank. What the problem is?

To make a long story short, after replacing the timing chains, guides, and tensioners, the right side cylinder head began running very loud. Think of the usual chatter associated with these engines and multiply it. It was constant, from start up to shut down, and it increased with rpm. Thought at first it may be caused by debris in the oil clogging the lifter(s). After changing the oil multiple times along with different additives and driving roughly 600 miles, the noise persisted. Taking a look down the oil filler tube with a flashlight and with the engine running, the head looked dry. Safe to say at this point I was starving the head of oil.
Removed the valve cover. Removed the rearmost camshaft cap. Sure enough, the oil passage was completely blocked. Inspected everything and there was signs of running dry (minor discoloration, dried oil spots... but no real damage and no play anywhere. Put it all back together and the truck runs quieter than the day a bought it.
Here's the camshaft cap:
This is exactly what it looked like after removal. The material blocking the passage is hard and bridle like plastic.

I have a 2004 to 250 super duty 5.4 and automatic trans it has about 233,000 miles on it. Yesterday when I started my truck I could see my reverse lights were stuck on against the garage door in the dark. After I put the truck in drive the lights went out later on I shift at the truck and to park and the starter engaged I put the truck in neutral and it stopped the starter from running after doing that several times the truck now does it even when it's in reverse or neutral. I have to leave it in drive and push the emergency brake on I am in and out of the truck all day long. I did change the shift to blast may I check the screws on the back of the shift to bury thing seems fine.

The rear tail lights on my truck have been out for a while now. I wasn't doing much driving at night so it wasn't much of a bother but the new job is getting me home a little later and having to drive with my hazards on is getting old fast.
My radio wasn't working either and I disconnected it a while back hoping maybe it had something to do with my lights shorting out but no luck. It remains disconnected. Just in the past few days my front running lights have went out as well.
I've tested all fuses multiple times (and replaced a couple of them) and checked and replaced bulbs. My brake lights, headlights, dash lights and hazards all work fine. I have the trailer light hook up on the rear bumper and disconnected it at the wiring harness as well hoping it was the problem but it wasn't.

Since yesterday, every time I turn the key off and remove it from the ignition the truck just keeps running. Engine, radio, according and everything just like the key was still there. When I press the unlock button it shuts everything down. It is a 2014 F250 with 4500 miles on it. I don't know if I did something or what but I am confused.

I have a 1999 Ford F350 5.4L 4x4. I had a check engine code on my truck a couple of months ago. The truck was running fine then. The light went away and I forgot about the issue. In the last week the truck began to run like crap; hesitation during hwy speeds. The truck is running with hesitation in 3rd, 4th, and 5th gear. In low gears the truck seems to run just fine. I have changed the EGR valve as well as the fuel filter. Check engine light is not on but the problem has not gotten any better.

My 1999 f-250 superduty shows overheating after it runs for awhile but it doesn't actually overheat the gauge just shows it. What it does is drops down to four cylinders. Is my heads blown or could it be something else it has 260,000 on the engine.

I just bought my first Ford. Its a 2003 F250 SD with 5.4L, 5 speed manual, extended cab, 2WD. The truck is experiencing intermittent problems with the clutch pedal.
If I depress the clutch pedal for a long time, then sometimes it does not retract all the way. It does this, for example, when I am at a traffic light waiting for the next opportunity to make a left hand turn.
The truck runs and operates as it should even when this does happen. The easy response is to place your toes under the clutch pedal and pull it aft to its completely released position.
The master and slave cylinder and the booster spring attached to the clutch pedal assembly have been replaced and this condition still continues.

The other day I got in my truck and started down the driveway when I realized I had no brakes, I slowly backed up and parked it. I haven't driven the truck for approx. 2 weeks and it seemed fine then. The master cylinder is full, there are no signs of leakage from wheel cylinders or lines. Today I unscrewed the left front zert and no fluid came out. My pedal goes all the way to the floor.... Whats going on, and if its a easy fix?
