Ford F-150 (2004-2008) :: 2006 Truck Starts To Skip And Shudder Under Acceleration At Around 40 - 45 MPH

I just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.

Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.

I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.

When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.

Ford Super Duty (1999-2016) :: 2001 F350 Truck Won't Do Over 30 MPH / Engine Starts To Sputter And Back Fire

I recently bought a 2001 f-350 xl 4 door with the 8 foot box it has the 5.4L triton v8. I was heading to a job up in northern Alberta about 10 hours away from where I live. On the drive I lost control of the truck on some black ice I was doing about 50 miles I went into the ditch but nothing crazy drove right out after. Now my truck won't do over 30 mph the engine starts to sputter and back fire I loose all my power, what's going on. At idle she revs fine but as soon as I put her into drive it's like she wants to die what can it be?

Ford F-150 (2004-2008) :: Rear End Starts Locking Up When Put Truck In 4wd

When I put truck in 4wd rear end starts locking up. Take out of 4wd its fine. Just put 2 quarts of fluid. They didn't have the 75-140 so I put in 85-140 was that bad. Had rear rebuilt a year ago. Mechanic said he had to put a different gear assembly because ford didn't make the original any more. Ever since this was done rear just never seemed right. Now in 4wd if I go straight it's fine but as soon as I make a turn rear locks up almost coming to a grinding stop.

Ford F-150 (2004-2008) :: Truck Starts To Shutter When Slowing Down

Read a few references but nothing seems the same as what I have... 2001 Ford F150 Larite 5.4L 4 x 4

When slowing down, at speeds of 3 to 4 miles per hours truck starts to shutter. It is not an engine issue, nor a brake as it will occur with brakes on or not applied. Engine is running smooth, seems more mechanical that fuel or brake related. Shutter is not slight either.

Both CV axles, hubs, rotors and upper and lower A Frames have been replaced. Shutter was happening prior to the replacement, they were replaced as preventive maintenance. Shutter is profound enough to shake the mirrors. What it can be.

Ford F-150 (2004-2008) :: Vibration Starts Above 45 MPH - Truck Shake Only When Pulling A Trailer?

I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?

Ford F-150 (2004-2008) :: Truck Starts Then Dies A Few Seconds Later And Battery Light Illuminates

This is concerning my little brothers truck. It is a 2008 4.2 liter with around 55,000 miles on it.

He drove it to work today, and called me this afternoon saying that the truck starts then dies a few seconds later, and the battery light illuminates. He and a coworker checked the battery and connections....cleaned off corrosion on terminals, battery reads 12.xx volts without a load on it, it is the original though.

As of right now he is changing the fuel filter which hasn't been done yet. I also know of issues with the fuel pump driver module. I remember checking the one on my 2005 back when I owned it. As I recall it causes a no start condition, but would it cause a start then stop condition like this? He will check this when he is done with the filter.

Anything else that we can check in a parking lot to try and at least get it home?

Ford F-150 (2004-2008) :: Rumble / Shudder In Truck On Initial Acceleration

Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.

Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.

Ford F-150 (2004-2008) :: 2006 - Truck Downshifted And Falls On Face Under Hard Acceleration

I have an 06 F150 2wd with the 5.4. Today on my way home I had to cross traffic while getting on the highway and had to get on it a bit. When I gave it the gas the truck down shifted then just fell on it's face until I let off the gas a little then it sped up like normal. It normally runs great but I don't get on it much. I just don't see why It runs great until I try to get a move on.

Golf V R32 :: Crank Then Sputter And Kick In Occasionally On Hot Days

Occasionally, on hot days, I go out to the car for lunch and it doesn't want to start. Crank it for like 5 seconds, let it sit, then crank it again and it will "sputter" and kick in. No CELs, no errors that I can find with VCDS.

My door switch is not the problem (the MFD shows the open door, and I am hearing the fuel pump prime).

I do seem to notice it more if my gas tank is less than half full, possibly needs to be lower than that (around a quarter).

Once it's running, it runs fine. I put in new plugs about 5k ago. Car has just over 50,000 miles on it.

It seems like lack of fuel delivery, but I'm not sure why. When the pump primes, could it just pushing vapor up the lines rather than actual fuel? (How would this even happen?) How often is the fuel filter supposed to be replaced?

One other thing to note - once or twice when it was VERY cold (sub zero F), the gas gauge got wonky like something was wrong with my sending unit. It read zero when it had read 1/2 earlier in the day. Haven't had any other issues with it that I can remember. Are the sending unit and pump one piece on this car, perhaps mine just needs to be replaced? (Don't have the Bentley handy right now to check.)

Ford F-150 (2004-2008) :: 2005 Truck Going Into 4x4 Lo By Itself

I've got a 2005 F-150 (5.4 triton) with about 35k miles that I rarely use in 4x4 mode. The other day, after stopping to fill up with gas, the truck 4x4 Lo light was on after starting it. The dashboard switch was still in 2H mode as I never switched it. I first thought that the dashboard light might be in error, but when I began to pull out of the gas station. the truck was in fact in 4x4 Lo. I had forgotten how to cycle it back to 2H so I slowly drove about 3 miles home at 20 mph.

Once home, I re-read the tranny sync sequence and managed to get back to 4x2. I called the dealer who never heard of a truck getting into that Lo mode w/o activating the switch and suggested that I just monitor it. I read a number of forum threads discussing the IWE and solenoid problems, but all of those threads dealt with issues of not being able to get too 4x4 mode. My biggest concern is that I leave in a month for a 2000 mile trip, towing a cargo trailer and I'd hate to inadvertently switch into 4/4 when traveling 60 mpg on a highway.

Ford F-150 (2004-2008) :: 2005 XLT Shaking Under Light Acceleration

I have a 2005 F150 XLT with a 5.4 (198,000miles) RWD. A few months back it developed a miss due to bad COP's, typical shuddering around 50-60 MPH.

I pulled off the COPs and while I was in there I pulled my old plugs as well. New Motorcraft SP515 plugs went in with a little nickle anti-seize being careful not to get any near the end of the plug and I put a set of Granatelli COPs on with a little di-electric grease on the inside of the boot. The miss went away and the truck drove like a champ.

I will also note that I replaced the front wheel hub/rotors, front calipers and new pads. I resurfaced the rear rotors, new pads and new E-brake shoes also.

The issue I am having is under light acceleration, or "normal" driving conditions the vehicle has a mild shake which eventually smooths out.

My first assumption was that I did not torque my front wheel hubs correctly or that I messed something up so I took the truck to my local front end/alignment shop for a full inspection and they said everything is great. They also said that they didn't really feel the vibrations that I mentioned. I am used to this truck driving very smooth up until the misfire situation so to me it is quit noticeable. After the front end shop I went to Discount tire cause they mentioned that my rear wheels are bouncing pretty good and that may be what I am noticing. Turns out the tires were out of balance which Discount took care of and rotated my tires while I was there.

The vibration is STILL THERE! No CELs to reference, just an obnoxious vibration. I tried to isolate the issue by accelerating in 1,2, and in D. The issue occurs regardless of the gear I start off in.

Ford F-150 (2004-2008) :: 2005 - Vibration At 75 Kms Throughout The Whole Truck

I'm having an issue with my 2005 f150 xlt. Its been happening for almost near a month and still cant locate the issue .

It has a vibration at 75km throughout the whole truck. Ive tried multiple things done to it by a mechanic, such as having the tires balanced and the ujoints replaced. The problem still persisted and after attempting to test out to see if press/releasing the parking break (my mechani suggested trying that out), my driveshaft fell off.

Apparently the center bearing snapped and cant simply be replaced on the 05's. So i had to get a new driveshaft installed (used, both the 3 mechanics I've gone to say its in good condition).

Even after replacing the driveshaft the issue persists - however it seems a bit softer than it was (I am guessing the old driveshaft was worn from the vibration causing it to be worse). After that I took it to another shop to see if they could locate the issue. They did a driveline inspection and engine inspection too see if a misfire could be the cause.

Again, nothing was found. The only thing they were able to find was that the issue only happens under load and slightly occurs at 40 and 100km as well (although alot softer then the one at 75) and they say they cant find anything physically and it was a mystery to them.

Ford F-150 (2004-2008) :: 2005 - Air Escaping Kind Of Noise During Acceleration

Just bought a 2005 4.6Lused. There is a "air escaping" kind of noise during acceleration. It sounds just like the AC system does sometimes after you turn off an engine. I thought originally that it by be AC related, but doesn't appear to be. At steady speed, it goes away, but comes on again with the slightest bit more gas pedal. In cruise control, it cycles on and off when the cruise accelerates up a hill,, etc. The sound is on the driver's side apparently close to dash corner.

Ford F-150 (2004-2008) :: 2005 Truck Bucked And Cut Out When Accelerate

Well I have had a completely dependable truck until today. I was driving my truck on the way home, its an FX4 with only 33K miles on it that i have had since new. I went to accelerate to pass some cyclists (not a hard acceleration) and the vehicle cut off seemed like it kind of bucked a little as if it was shifting gears hard. I got a service light but what was weird was the gauges worked and the RPM still showed 1000. I did have power still though as the radio was on. The only thing that is currently wrong with the vehicle is the odometer gauge is out and needs to be replaced.

Anyway I shifted to neutral and restarted on the fly and than shifted back into drive and it drove the rest of the way home fine. After i got it to my neighborhood i ran it hard and it did not cut off again. I do not want this vehicle to cut out of me in town in the middle of traffic or while i am driving my 18 month old around and i get disabled with her in the truck. Slug of water maybe? I filled up on monday and still have around 3/4 of a tank of gas. Maybe short because of the gauge issue getting worse? I have the crazy door locks and beeps but nothing else has occurred. 05 F150 FX4 5.4 ....
