Ford F-150 (2004-2008) :: 2007 - Chug While Accelerating Around 40 - 45 MPH
Apr 14, 2016
i have a 2007 F150 Fx4, with 94,000 miles. When I hit the speed of around 40-45 and I step on the gas it starts to chug until I press harder down the it gets out and runs just fine. The thing that confuses me is it doesn't always do it. Id say about 3 times a week. I am replacing my fuel filter tomorrow. I purchased this truck with 85k on it, and this just started happening. The spark plugs have never been changed. And am thinking about taking it in to get those done too. I also tested all my injectors and they are all working. No codes have been thrown either.

Strange noise from what sounds like the suspension when I accelerate and then when I turn also. Truck was in Hawaii so that might have something to do with it. How do I get these noises to stop?

So I bought this 2007 used with 86K on the engine. After 2 days cats code went off and i had both replaced with brand new ones. Now my truck is making a rattling as i step on the gas at about 2500 rpms. Its sounds like metal in a can swirling around amd as i let off gas the sound stops. It happens often, also the other day in was pulling off and heard a grind for about 2 seconds then stopped never beard it again, it sounds like its coming from the rear passenger side. It sounds like a bearing. This is the noise.

So running into an issue with boost numbers. Factory gauge reads between 20-30lbs on throttle, but I have a SCT x4 and it only reads 3lbs and at idle it only reads .25-.89 somewhere around that range. Are these numbers accurate?
Also, it has developed a sort of buck or chug at like quarter throttle while accelerating, it's sluggish leaving stop signs etc. and it sounds like the waste gate or blow off it holding on even after I let off of the throttle.

I have a 2009 honda accord, v6, auto, 46k. It has recently started to chug, most of the time, not always. I feel it in the gas pedal. Kind of a jerking, hesitation chug while accelerating. It only chugs between 20-40 mph, disappears after that. Someone suggested a spark plug problem, but I can't imagine it's that since it disappears after 40mph. Could it be a transmission problem?

Ok, I have done some reading here and from what I can tell I don't think that it is the cam phasers or solenoid. This only ticks when you give it gas. Sounds fine at idle, going down hill, anytime I am not on the gas. Injectors maybe?

Truck is 08' with 5.4, 3.55 gears, auto trans. 84k miles. Recently purchased from the TSA fleet trucks, so I have no clue what PM procedures were done prior to me getting it.
I noticed the following: when I get the truck into OD and then slowly decelerate (meaning I let it coast and im not braking) to about 40mph then get on the gas (normal acceleration) the truck bucks hard almost like when your spinning wheels on snow or ice and put the truck in 4wd and the front rear locks. or a limited slip rear that catches when one wheel is spinning.
if I accelerate hard the truck pushes thru it and doesn't buck as bad. I have searched this out and there are several threads about it that describe just about exactly what im talking about, the following have been brought up as possible problems:
1) bad spark plug/s and or coil/s
this seems to be the most common answer to the possible problem.
2)broke valve spring
3) bad torque convertor
So at 84k miles im thinking replacing the spark plugs would be fine to do as a PM. So coils.............should I just go ahead and replace them as well? I found them (motorcraft). does that seem right?
As far as spark plugs, I have already read the horror stories on the 04-08's breaking the plug in the head. I have also read that before 10/07 was the trucks that had the issue. my build date is 02/08. am I good to go with normal removal of the plugs? the best method I have read for removing them is spray carb cleaner down the hole and let it soak overnight and then the next day drive the truck get it nice and hot and remove them right after you park it,,,,

I have a 2004 F-150 5.4 Liter 4X4 supercrew with 6" lift and 35" tires. The truck has 123K miles on it. I am the second owner of the truck. In early fall the truck started making what I can only describe as a mild and inconsistent "stutter" upon accelerating between 40-50 MPH. It does not do it all of the time and really depends on the speed at which you accelerate. Sometimes it will happen between 50-55 MPH but primarily it is between 40-50. If you accelerate quickly though at that speed, it rarely ever happens.
Anyways, I changed the fuel filter (pretty sure it was the original as it was nasty and had chunks falling out of it), flushed the fuel injector system at a shop, gassed it up and treated the tank with fuel treatment, and removed the AIRRAID air filter, cleaned it out (blew out with air, flushed with water, dried and re-oiled it). The truck had A LOT more power behind it, my fuel mileage increased and for about a day, this stuttering did not occur. It has now started up again.
My question is whether or not this could be caused by old spark plugs or is it a transmission issue? The truck runs great otherwise. We've looked at the plugs and they appear to be the original plugs. I bought the truck with about 100K on it and have put the rest of the miles on myself. I'm trying to figure out if it is an issue with the plugs or if it is related to the automatic transmission as I'm sure the fluid hasn't been changed in it either. I know I'm going to have to do both but want to know what is more likely the issue at hand.

I've been living with a mild "clunk" or "bump" in the drive train when I would first begin to accelerate from a full complete stop. It would only happen after a complete stop. It almost felt like it could be normal, but it seemed to be getting worse over time.
At first I thought it was my transmission...but after some internet searching I found some threads talking about the slip yoke on the drive shaft being the cause. In that the slip yoke needs to be pulled apart and re-lubed.
Anyway, I thought I'd post and let eveyone know that after pulling the slip yoke and re-lubing with grease my issue is solved! The "clunk" is totally gone. 100% Smooth now. If has this issue I'd highly recommend re-lubing the slip yoke.

On my 2004 F-150 SuperCrew, all I needed to do was remove the drive shaft at the rear differential (4 bolts, use 12mm 12 point socket or wrench). Then remove the FRONT clamp on the slip yoke boot. Then slide out the rear 1/2 of the drive shaft. Be sure to mark the drive shaft orientation with the rear differential flange and the slip yoke before you remove the drive shaft to ensure you put it back together correctly.
Re-lube the slip yoke, then slide it back together and reinstall the four bolts at the rear differential. Torque spec is 76 ft-lbs. I used Valvoline FORD-LINCOLN-MERCURY moly grease that I purchased at my local AutoZone. You'll also need to install a new band clamp around the rubber slip yoke boot. I got mine from AutoZone.
Here are some links I found with pictures showing how to do this. Both procedures below are on SuperDuties but its basically the same procedure. Just follow my specific details above for the 2004-2008 F-150

i own a 2005 f150 supercrew fx4. Today as I was attempting to go out of town I was accelerating up hill and heard a noise, sounded like air coming through a window seal or scratching, which is not the problem. The noise only came on when i increased the acceleration, there is no power loss, the truck still accelerated properly and had good power, just that the noise came on. so i returned home only to hear the problem on flat land also, when pressing the gas to accelerate. The truck seems to idle fine and have no problem with low acceleration.

my 05 is giving me these mini shakes when I accelerate and slow down. I also get a little bit at highway speeds. I was walking around the truck today and I noticed that the back right tire doesn't have a weight on it. I thought this was wierd. Could a weight have fallen off thus causing the vibrations, or is this normal for one wheel to not have a weight?

I purchased a 2006 Ford F-150 XLT, 5.4 3V Triton. Last Thursday my check engine light came on, so I came to this forum and found out how to retrieve the code with out a OBD. It came up as a 0301 Misfire cylinder 1-10?
I went to the dealer and they said it was cylinder one, sold me a new plug and coil pack and they installed it for a nice $$$. On my way home it started to sputter again when you give it heavy throttle, I called they told me that I should change all the plugs and Coil packs, kinda makes sense but to have all 8 plugs and coils go at once it only has 83km on it.

Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.
It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.

I just bought a 2006 f150 exteneded cab w/ 5.4 V-8 and it vibrates when accelerating from a stopped position but not all the time---happens more when the wheel is turned. It definitely feels like the vib is coming from the left front side. I just got it back from the shop and the mechanic told me the vibration was stemming from the rear and that he exhchanged the fluid and added anti-friction additiver but that he expects the problem to continue.

I've had my 2006 XLT F150 (5.4L) for about a month now and have recently noticed what I can only describe as a 'smacking' sound under my truck when I accelerate quickly. It sounds as if I had something stuck to my drive shaft that is slapping the underside of my truck....except I don't. I don't think that its the timing chain because it seems to be coming from under the cab (between drivers/passenger seat maybe). I hear it most often if I try to quickly accelerate from a normal speed (50mph or so) to pass another vehicle. I do not hear it otherwise. Starts with a 'tink tink' then sounds like something hitting the underside. I'm perplexed at what this could be.

I have a 2006 f150 5.4l, and I have developed a problem. It seems the my truck has started to skip, or "pulsate" when I am accelerating. If I really get on the gas the "pulsate" goes away. This only seems to happen around 45-50 mph. Now this is where it gets weird. I have no check engine light on, and I have checked to make sure my light is working. I brought it to a garage and they told me something about Fords having a misfire issue that sometimes doesn't trigger a check engine light. . . . . now idk about that because every misfire I have seen triggers a check engine light, but I had them replace the spark plugs anyways. And it didn't fix my problem. At this point the only thing I can think of is possibly tranny.

I recently bought an 04 lariat crew cab with 56K miles 5.4 and auto trans. Before i bought it i complained about an exhaust noise and acceleration issue at 40mph and 1100 rpm as well as the ac not being very cold. They replaced the exhaust manifold on the passenger side, coil pack on the #3 cylinder, a transmission flush, a flash drive update and recharged the ac. This seemed to take care of the problem but i mostly drove under 30mph and did not notice it. I took it on a few road trips, and country roads and noticed the problem of sputtering and shuttering between 40-60 mph's after decelerating and slowly accelerating. The problem occurs consistently with ac and over-drive on in the above mentioned conditions and mph range. Problem is less noticeable with ac off and have not noticed it at all with over-drive off. It feels like a limited slip kicking in or driving on dry pavement in 4wd. Tranny shifts fine through all gears in a straight pull of acceleration and even full throttle pulls. Problem only occurs after decelerating and slowly accelerating. I don't know of any codes as I don't have a code reader, but I have not had any check engine lights come on nor has the dealer mentioned any codes.

I just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.

i just picked up an 06 f150 with 5.4l 4x4 xlt package. Love the truck as it is my 1st Ford HOWEVER..... the truck is running super rough at idle and keep getting code for cylinder 5 misfire and bank 2 lean (which i am assuming is from cyl 5). here is what i have done so far...
New Coil packs
New spark plugs
New fuel module
New fuel injector on cyl 5
Still has a "stumble" when accelerating around 45 mph and shows code for cyl 5 misfire then will then throw code for bank 2 lean.

I'm noticing more and more on the highway when i accelerate that my car seems to pull to one side then when it shifts it snaps back. I'm not really sure if I'm even describing a transmission issue or a power steering issue. Basically, it just seems to pull and snap back fairly strongly, enough to cause a slight swerve as it shifts during acceleration. Where to start on something like this? (no error codes or check engine lights. Also no vibrations or other sounds).

I have a 2008 Santa Fe LTD, and just recently started experiencing a strange noise when I am accelerating, and I cannot pinpoint it. Here is some info on the noise.
-2008 Santa Fe LTD AWD, about 25,000 miles
-Sounds like a little higher pitched hum, not very loud
-Seems to be coming from somewhere near the passenger side backseat area (first found out about it when someone was sitting there and asked what the noise was)
-Cannot tell whether it is coming from the interior or exterior of the car, but I think exterior, but it is definitely somewhere along the passenger side, from the back half of the car.
-Noise occurs when accelerating from a stopped position, only when accelerating, never when braking or idle.
-Noise occurs only when car is in gear (hitting the gas pedal in park does not cause the noise to happen)
-Noise doesn't occur at high speeds or when accelerating at high speeds
-Noise only really occurs for a 2-3 seconds while accelerating, then seems to go away as I continue to drive.
-Noise doesn't seem to always happen, but very frequently.
