Ford F-150 (2004-2008) :: 2006 - Started Skipping Or Pulsate When Accelerating?
Jun 5, 2016
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 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 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 just completed a successful second spark plug change, using Motorcraft SP515 plugs just like last time. After reconnecting battery and starting engine, it ran poorly throughout a short road test. Felt like it was skipping. Checked under the hood and found that the #2 fuel injector was disconnected, so I reconnected the injector.
I took another short road trip and it still ran poorly as if skipping. So, this time I disconnected the battery for several minutes while removing the #2 plug thinking I may possibly have fouled the plug by the injector not being connected. I also checked all of the other injector and coil connections. Reconnected battery and took another short trip. It still runs poorly. No codes yet.

So I have a 2006 f150 a wile back the steering started going stiff when I would come off the highway. so after some forum searching, I decided to buy a new steering shaft to repace the universals that see up. then the pump started squealing when we turned befor I could install the new shaft. so I replaced the pump and didn't put the new steering shaft in yet. now when I rev the motor past 2000 RPM the pump wines like when you turn the weeks to far to one side on an old truck and it is still stiff when I come off the highway. Could this be the rack

I have a 2006 F150 FX4 and after having the 4x4 go out and replaced the front right IWE have fixed the 4x4 but still hearing a clunking noise.
The clunking noise started after the 4x4 went out and was really bad for awhile and then went away and has now come back really bad. It sounds like its coming from the front driver's side wheel area and clunks as fast as the wheel turns.(faster = more clunks).
I'm very new to mechanic stuff but enjoy learning and fixing things myself.

My '06 Ford F-150, 4.6 V8 is smoking when I start it up occasionally. The smoke color is blue. The only mod is flowmaster exhaust. Bad injector, sticking valve......
Where would you start? I am all for supporting a local mechanic but financially I do not have the money to gamble. Once I can pinpoint the problem I will take it to them to fix.

I have a 2008 Elantra with 50,000 miles. I know I was overdue on the tranny fluid change and the car was getting bad gas mileage and skipping gears. I brought it in and had the tranny flushed and refilled and now its running good. I thought it would be good to get a price on spark plugs because the book said replace at 60,000. I called the dealer and he basically told me he has not sold many of the plugs and they should last 100,000.
I seem to be getting conflicting info on what should and should not be done at the maintenance books written schedule. I looked for a price on Fuel Filter air filter which is in the maintenance to replace but again conflicting info stating that should not be changed unless there is a problem. Anyway, what should and should not be replaced at specified intervals? I know the tranny fluid change should have been done at 30,000 because it was very dirty and causing issues for me.

I have a Ford F150 XLT. I have 67000 miles on it and the other night it just started running rough out of no where near idle. Once you got over 20mph the rough running would go away. I took it to get an engine change and engine flushed but it came back. It doesnt always run rough near idle or below 20mph. The Ford dealer says my engine has only 22 psi oil pressure near hot idle and cant engage the VCT phazers and they want to replace the whole engine.

My alarm started going off by itself and my truck would not start so we unhooked the horn but the alarm was still trying to go off making a ticking noise when the horn should have been honking. so we also unhooked the alarm. And it started right up. I've been driving it with those things off with no problem. But today it wouldn't start again and its making a ticking noise like the horn is trying to honk.

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%
[Code].....

Back in April, I posted this comment about occasional skipping when accelerating: "I have a 2003 Buick LeSabre with 187,000 miles (mostly highway) that skips/jerks sometimes when accelerating, even when in cruise control. It only does this every month or so; and, of course, never does it when the mechanic is in the car. No warning lights have ever appeared and my mechanic says no codes have shown up in three diagnostic tests.
In the last 1.5 years, the following items have been replaced: power steering rack, oil pressure sensor, FE control arm bushing, intake manifold gasket, oil pan gasket, transmission mount, water pump, rear struts. In 2010, an alternator, thermostat, mass air flow sensor and front brake pads were installed. Oil is changed as scheduled; tires are rotated as required and car is serviced at the first sign of any problem. Other than occasional skipping, car is in pristine condition and rides like a charm. The most recent skipping occurred March 29th when I was 200 miles from home. It lasted sporadically for about 10 miles and did not occur in the other 190 miles."
Based on the advice of responders, I had the fuel filter replaced and the car never skipped again ... until today, three days after the rotors and brakes were replaced. Like before, there have been no warning lights and the skip, which can occur when braking or when in motion, occurs sporadically. It might happen several times in a mile and then not happen again for some time. The car now has 192,000 miles. Is this the transmission, a problem with the recent brake installation or something else?

I have a 98 Toyota sienna and it has started making a thud noise and skipping a bit when accelerating or going up even a slight incline. I have been told everything from it needs new plugs/wires to a new transmission. Could these cause similar problems?

I brought my Outback to one mechanic due to overheating and a strange skipping feeling when accelerating. First mechanic said head gaskets needed to be replaced, I wasn't surprised since I have about 142k miles on it and it has been leaking oil, quoted between $1800 and $2000. I took it to another shop, recommended by a friend, and they agreed the gaskets needed to be replaced and there was also a misfire due to the spark plugs. This shop quoted me at $2200-2600 for the head gaskets, spark plugs, all wires and timing belt, all other engine gaskets, thermostat, engine oil and coolant. I still owe a good bit on this car (parents bought on the fly from a less than stellar used lot and now it is my problem), and my thinking is I do not want to bring on more debt by attempting to trade this one in and go for a new car. My question is, do I go with the second mechanic that wants to basically rebuild to top of my engine, or would I be ok limiting the repairs to the head gaskets and spark plugs?

About a week ago, my wife's Malibu (~130,000 mi) started exhibiting symptoms I would associate with a problem with the ignition system. It was idling rough, it felt like it was misfiring, and the check engine light started blinking when I was accelerating from stop up to 30-40 mph.
The timing was all weird because of the holiday, and so I didn't take it to get the engine codes pulled right away because I figured Id take care of it this week (we were traveling over the weekend).
My wife just called and said her car won't start at all. The car will try to turn over and she didn't describe anything consistent with a dead battery.
If I can't get it somewhere to get the codes pulled, what might be wrong? To summarize, it started idling roughly and maybe misfiring about a week ago, it sat for four or five days, and now it won't start.

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,,,,
