Ford F-150 (2004-2008) :: 2006 XLT Vibrates Between 50 - 60 MPH
Recently I noticed a "thunking" noise when I accelerated from a stop and a vibration between 50 and 60 MPH. For what it is worth, I baby this vehicle. I took it to the shop and had three U-joints replaced, the next day I noticed a severe vibration was still there. I returned to the shop where they kept it for two days and cannot figure out what is causing the problem.
They re-balanced the tires, checked the alignment, brakes, calipers, rotors and even had the drive shaft re-balanced (which they said was out by 30,000) and took it to a local transmission shop who said the problem is not in the transmission but it is still occurring. They finally admitted defeat and suggested I take it to the dealer. It has 149+ thousand miles on it and a 5.4 engine.
Ford F-150 (2004-2008) :: 2006 - ABS Vibrates After Start Up - Common?
I recently bought a 2006 screw. When first started ,upon take off in drive,just as you get into the gas it has a vibration for a few seconds. Only does it once just after each start up.
Took it to the dealer they said it was abs motor running a test cycle. They checked another 2006 on the lot and it did the same thing. You can feel it through the accelerator pedal and it really annoys me. Is it common to only 2006 models?

View 4 RepliesLexus LX 2008+ :: Vehicle Vibrates Whether Driving, Accelerating Or Decelerating
I have just purchased a brand new LX570.
I can only explain that the vehicle vibrates. Whether driving, accelerating or decelerating there is a constant vibration just like driving on a poor road surface. We have superbly flat and new Roads in Dubai, and I drive them every day in my 2 other (far less expensive) 4WD's and I do not feel shaken, stirred or positively nauseous. The only time u feel at ease in my new Lexus is when I am stationary. Transmission also occasionally lags and I can feel the gear changes, sometimes a judder and a bit of a jump as it searches for the gear. Take off is sluggish (i know it's a big car!) but I feel it's not good enough for the car that it is supposed to be.
This is my first Lexus. I opted for the full top of the range with s few extra options and a big spend. This is certainly not the car I was expecting and it is definitely not the Lexus experience that I thought that I would get. What is the problem with vibration? The whole body shakes ( not the steering wheel) albeit mildly, it vibrates almost constantly. it is simply not a smooth drive.
The Lexus service centre has changed all the tyres at 100 km claiming flat spots due to transit and storage. The car now has 300 km on the clock. It's not the tyres or the alignment. They claim to have run full diagnostics but found nothing. I can't believe that his issue is on my car only. I have taken 2 other drivers out and they agree with my concerns, something is definitely wrong.
Ford F-150 (2004-2008) :: Brake Lights On Whilst Truck Not Running?
At 2:30am this morning I looked out my window and saw my brake lights and third brake light come on for about 5 seconds and then go off. This scenario kept repeating itself. I went to drive my truck 2007, and the brake lights remained on even when the lights were turned off when I was driving. I also need to seal the third light. Brake regulator has been replaced.

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.
Ford F-150 (2004-2008) :: 2006 5.4L - Shaking When Slightly Accelerating
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.
Ford F-150 (2004-2008) :: 2006 XLT - Smacking Sound When Accelerating
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.
View 6 RepliesFord F-150 (2004-2008) :: 2006 - Started Skipping Or Pulsate When Accelerating?
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 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.
Ford F-150 - 1997-2003 :: 2002 - Bucking Whilst Accelerating?
I have 2002 4.2L F150 w/ Manual Transmission. The problem I have started about a week ago. I noticed it started to idle very rough and at times felt like it would almost stall if i didn't keep giving it some gas. Then a few days later it started to jerk/and buck intermittently while accelerating. I changed out the plugs and wires. My coil pack was replaced a year ago but was still under warranty so i installed a new one just in case. I cleaned and inspected the EGR valve and replaced the TPS. The rough idling seems to have cleared up but the jerking/and bucking still remains.
When the engine is cold the truck runs fine, and then as the engine starts to warm up it will jerk and buck while accelerating at any speed. Once the engine has reached its optimal temperature the jerking/bucking goes away and it runs smooth as silk. I can drive it for for a few hours with no issues whatsoever. As soon as the engine cools, the cycle starts all over again. I figured maybe the intake gaskets were on their last legs and when they heat up they seal tighter causing the engine to smooth out.
So I replaced the upper and lower plenum gaskets today and cleaned everything up. It still did not fix the problem.
Ford F-150 (2004-2008) :: Torque Converter Vibrates Between 40 - 55 MPH
I highjacked another thread yesterday but didn't get many responses so I thought I would start a new one... I've done some searching here but no one had any real answers or had a different reason for the vibration...
We have a stock '05 F150 with 24k mi that is having Vibrations not related to bad tires or a bad trailer. It rattles any cups or change that is in the center console area and the dashboard. It seems to come up through the floor.
Symptoms timeline:
The rear pops when you turn tight in a parking lot. I've been told this is normal because of the ratcheting LSD? Is this true?
The tranny fluid was low and we could not find where it was going. Put several qts in it and finally took it to the dealer where they replaced the bad seal between the transmission and transfer case. So we know they took the driveshaft out and the transfer case. Not sure if they dropped the transmission out.
We have a vibration from about 40mph-55mph under medium-full throttle. A lot worse when towing. Put it in neutral and it goes away. Rev the motor and you don't feel it. Only happens under load. Happens in 3 and 4th gear. Goes away once the torque converter locks up.
Am I going down the right path in saying it's a bad torque converter?
Sonata NF (2006-10) :: 2008 - Steering Wheel Vibrates At Idle
I just bought a 2008 Sonata GLS 2.4L, 4-cyl., automatic, 74000 miles.
I found that the steering wheel, sometimes the seat, vibrates at idle in "D" and "R". And the vibration reduces a lot in "N".
Is this common for this model? If it's not common, how to repair this problem?
Ford F-150 (2004-2008) :: Ticking Only When Accelerating?
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?

Acura - Tl :: Engine Vibrates When Accelerating On Freeway
Recently I noticed my car vibrates to left and right when I hit the pedal and the speed is around 40mph and above. The car runs smooth if I maintain the speed.The car has 176K and running quite good and I am about to have the timing belt service.I am just curious what could cause this: timing belt? fuel filter? The car is 2001 acura TL so it has front wheel drive.
View 15 RepliesFord F-150 (2004-2008) :: Bucks / Jerks In OD Around 40 MPH When Accelerating
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,,,,
Ford F-150 (2004-2008) :: 2007 - Chug While Accelerating Around 40 - 45 MPH
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.
View 6 RepliesFord F-150 (2004-2008) :: Inconsistent Stutter Upon Accelerating Between 40 - 50 MPH
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.
