Ford F-150 (2004-2008) :: 2006 - Sputtering When Accelerating Heavy
Apr 27, 2009
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.

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.

Have a trusty 05 stx 4.6 4x4 automatic 44,000 orig. miles/owner ext cab pick up. Just lately I thought I picked up at tree branch or something make a noise very similar to pulling a hung up branch or something.. Stopped, looked under truck (everywhere) no dice! Then did some research.. Noise went away when not giving it gas or gliding in nuetral just when light or heavy accelerating! Where do I begin??

I've got an '06 F150 and the steering isn't right with it. It has had a heavy feel and is almost like the power assist is only working half as good as it should. It's been like this for a couple months. I 've had all four ball joints and the steering rack replaced in the last month. It had the heavy steering feel before and after everything was replaced. It also doesn't recover itself on sharp turns, I have to turn the wheel back as I complete the turn. Could it be the power steering pump? I thought it was a mechanical device and it either worked or it didn't, maybe they get weak?

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 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 have a 04 fx4. Was sputtering for awhile. The engine light came on. Now it won't start even with a boost. What it could be has 290 clicks.

I have an '05 5.4L 3V and I was way to trusting in how it was running. BTW, I change the oil every 3 to 5 and have only driven highway miles, albeit a lot of them...155k! I bought it with 40k on it but was not aware of the plug change issue until I heard about it off-hand. I let the plug change go cuz it was running so well. Bad move.
Anyways, a few weeks ago it began to lose power and I suspected that the PCM was retarding the timing for some reason. Before I could get to the shop, the thing went nuts on me at 75mph. Started shaking and sputtering and throwing cel codes. I shut it down and after 5 minutes re-started. It seemed fine and actually was running a bit better. Took it in and the code was the 0302. #2 cyl misfire.
They also said the compression was very low on that cylinder and slightly low on 1,3 and 7 as well. I had them change the plugs and the #2 COP even though they said I needed a new engine and then I picked it up. Now the engine barely runs at all. It shakes violently, where to go from here. What should I do now? New engine?

It started completely unexpectedly about a month ago when I was driving around 70kmh while cruising. I would get a few "jerks" of a sputter, then was able to drive a km or 2 before it did it again. I drove to a friends and he got in, and the sputtering episode was over.
Since then, I cannot simulate the way I was driving to make it sputter for any mechanic, but I have been getting sputter on and off the last month.
The one time I got in the truck and started it, put the truck in drive, and it sputtered for a few seconds. I wasnt driving at all this time. This was the only time It sputtered in a stading position.
Here are a few points to maybe, narrow down what happens.
-I am usually driving around 70-90kmh
-I am usually under no loads (not towing, hauling etc).
-My mileage seems to be getting worse.
-this was normally happening not only when the engine was warm, but when it was warm outside and I was driving it for a longer period.
-When I started driving my truck I calculated around 16mpg city. I am currently getting around 13-14. I was on the hiway for around 250 km and got 14mpg. Seems I get better mileage when puttering through the city than when I am on the highway.
I had the truck in to a dealer 2 weeks ago. They did an injector flush, new sparkies, number 5 coil, and took me for $780, saying the problem is fixed.
A few days ago, I was driving on the onramp to the highway accelerating around 90kmh and for around 4-5 seconds I was sputtering and jerking so bad I thought I was done for. The truck finally recovered and again, haven't had any episodes since.
The dealership says their electrician doesn't know what to do, and would need my truck for 4-5 days to try to see the problem for himself. I can only think, as a non-mechanic, that it is something to do with some sensor, possibly a fuel, and/or oxygen sensor.

Here's the story on my truck. Spits and sputters between 40-60 during heavy acceleration and on rare occasions will jerk/pop while at a steady speed. No engine or wrench lights. I thought it might be the fuel filter and changed that, it didn't work. I also ran two bottles (on 2 separate occasions) of Duralube extreme fuel system cleaner, that didn't work either. So, I took it to the Ford dealer for a diagnostic. They had a hard time getting it to act up but said it finally misfired on #8 and recommended replacing the ignition coil and plug. I did that, still have the same symptoms. So, I thought it might be the fuel injector and changed that. Still same symptoms and ZERO dummy lights.
After several YouTube videos, I thought it might be the TPS and got one. Before I changed that however, I cleaned the Mass Air Flow sensor, still same symptoms. I finally changed the TPS, but the engine wouldn't start or run at all, no warning lights yet. When I put the old TPS on, it would run. I unplugged the TPS and it still ran but very rough. Now the engine light IS on! Thinking I purchased a bad part, I took it back to O'Reilly's and they warrantied it out and gave me a new one. I had 19 PO codes. I changed the TPS again, and, it won't start or run at all. Put the old one on and it runs. They cleared the codes and told me they think it could be the ECM/PCM.
Why will a new TPS not work? I still have the same issue of hesitation @ 40-60 during hard acceleration. No hesitation during a moderate acceleration.

2006 F150 FX4 5.4L, 118k miles... At highway speeds (45-50) and (55-60) as I am slightly accelerating it feels like the transmission or maybe ignition system is skipping a beat. Kind of feels like a small bump. I replaced spark plugs with motocraft about 35K miles ago and recently all transmission fluid via cooler line. Had some concerns about system flush so I just drained and refilled entire system via cooler lines. I have read that it could be my COP's ...

i have an 07 ford f 150 5,4 liter. at speeds between 45 and 55 it has like a sputtering and jerking loss of power. I had a computer hooked up to it and it said fuel pump replaced it but it is still doing it, what this might be.

I have an F-150 Heritage 4.2L V6 Manual 4X4 and over the last few weeks have notice a couple of odd things. First I noted an odd screeching sound, similar to a rock caught in the break drum, but it seemed to be coming from under the cab/bed, not a tire. It only seemed to show up under relatively heavy throttle, which I thought was odd. I went through a car wash with a good under carriage spray, and the sound went away.
A few days later it snowed and the sound returned. I don't know that it's actually related...but that's how the weather went... Now, when I let off the throttle and the engine holds the truck back there is a "thump", and when I reapply the throttle, it thumps again. If I press the clutch in first, then release the throttle there is no thump; so I assume this is something with the drive shaft.
I climbed underneath and found that I do have some play in the shaft, I can twist it a tiny bit so I know that I have play in the shaft which (and I am NO mechanic) I assume is not normal. I can see the shaft turning all the way to where it goes into the back of the transmission so I assume the play is coming from the rear yoke?
I thought I could replace the yoke relatively cheaply but I keep stumbling across posts indicating that with this particular set up, I actually have to replace the whole drive shaft. What I could be looking at, and what my options are?

The ole 5.4l hit a snag today. I was on my way to fill her up and she started sputtering and damn near died! i filled her up and it was like nothing ever happened. Took her to AutoZone and the diagnosis was a Fuel Tank Pressure Sensor.
I have a connection with Bumper-to-Bumper to get the part for cheap but I'm not sure if i want to dive into either moving the bed or dropping the tank. I'd prefer to move the bed.

2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?

2003 F150 XLT 7700 4x4 5.4 Triton. While accelerating normally from a stop the transmission? shifts into 2nd with a heavy jerk. All other gears normal. It doesn't do this under hard acceleration or under very gentle and slow throttle application. Is this a COP issue, a transmission issue or just a driving style thing?
