Ford F-150 (2004-2008) :: Shuttering / Sputtering At 40 - 60 MPH After Decelerating And Slowly Accelerating
Aug 8, 2011
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 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 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.

I have a 2007 Ford Expedition with approx 135k miles with a 5.4. At approx 45 miles per hours it starts shaking and shuttering. It feels almost like you ran over one of those traffic bumps. I've had quite a few issues I've been working so I recently changed all my plugs with motorcraft platinum and all new COPs.
When I am going approx 45 miles per hour it will shutter for about 1-2 seconds with overdrive on. You can almost time it that it will do it every 4 seconds. With overdrive off, you can feel something dragging down the engine and hear a light grinding noise or a mechanical sound but the shuttering is less. I feel there is something definitely cycling approx every 4 seconds.
When i am doing heavy acceleration I feel that it has adequate power and now that I've replace the plugs/cops I don't feel any significant misses etc under hard acceleration (before I changed the plugs/cops I did feel misses).

I have had the check engine light on for a while now with the truck shuttering and bucking along with loss of power. Feels like there is something holding back the power. Just a couple days ago I was driving on the freeway and all of a sudden it felt like I was in neutral, tried to accelerate but the engine revved but wouldn't go anywhere, I clicked the overdrive on and it went into gear and I was able to drive home. Now every time I drive it, it goes a block or two in drive then again feels like neutral, put in overdrive and it goes into gear. I just put in new ignition coils.

I have a 2010 F150 Xlt super crew with a 4.6L. I've noticed lately when I start from a full stop the the truck has a small shutter or hesitation before it starts accelerating. Its barely noticable but it is there. What it could be? I had the tourque converter replaced just before my warranty was up, I've only put 30000 Km on it since. Was wondering if it could be the cause.

My truck is a 2004 (new body style) 4.6L XL Supercab 4x4, trans code A, which I believe is the 4R75W transmission. I bought the truck used last year with 110k miles on it and it still only has 115k now. I think the problem with the trans was there when I bought it (it's highly intermittent) which may be the reason why the PO traded it in, because the truck is in excellent shape and has clearly been well cared for in all other regards.
The problem only occurs after having let up off the accelerator pedal for a while and coasting, then getting back on the gas without coming to a complete stop, like one might do coasting downhill or coming up to a light that turns green before you come to a stop. When that happens it feels like the transmission has shifted into neutral and the engine revs up freely for a second or two and then suddenly engages and clunks / slams into drive. This doesn't happen every time that I attempt to reproduce it, and it went for the entire summer without doing it once. But, now that winter is coming on in New England I find that it is doing it again once in a while. The problem seems to happen whether overdrive is engaged or not.
I've checked fluid level and condition and both are fine. Nice bright red color and no burnt smell. The transmission works well in all other ways except for this one issue. With the exception of this problem it seems to be engaging, driving and shifting perfectly, with no slipping, even when giving it a good romp, with or without 4x4 engaged, or even carrying a heavy load, causes no problems.
To me, this seems like a control problem of some kind, doesn't it? If it was mechanical or hydraulic I wouldn't expect it to only occur after coasting for a while.

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.

2004 Ford Focus ZX3. Manual Transmission. Alternator replaced 1-2 years ago for different symptoms/issue.
My problem is that the headlights dim or flash (pulse down to very very dim then back to full) when accelerating or decelerating. Pretty much only when in gear.They will go back to normal when I depress the clutch pedal (usually I think) or am coasting in neutral. The fan in the car and other electrics/indicators seem to suffer from same power fluctuations too.
A little while after seeing this, I noticed a faint then more pronounced clicking coming from left side of dash. (Fuse/relay box?) It seemed to click when the "shift" light would pop on and off about 20% of the time the light did. Otherwise mostly when accel/decel.I started pulling relays and driving around a parking lot to see if it was one. The click seemed to disappear after pulling the horn relay. (And not the "Battery saver" relay next to it. Odd) The clicking issue does not happen all of the time when driving. The power dimming does.

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.

when i accelerate or let off the peddle I hear and aloud thug or dull bang. I've checked and greased all the u joints. Disconnected the carrier bearing and separated the drive shaft and greased it up. Still get the noise I have very little play in the carrier bearing but I don't think that's the problem. It sounds to me like might be at the transmission. What do y'all think it is?

I drove my wifes car today for the first time in forever, and I noticed that it makes a thumping sound between 10 and 20 mph. It does it whether I'm accelerating or decelerating, and it makes no difference whether I'm turning right or left. The car has 60K on it...

The vehicle in question is not our 2006 Passat
Car in Question:
2010 CC 2.0T DSG
12,4xx miles
I have noticed that when accelerating and decelerating I feel/hear an annoying clunk. I remember reading about this issue when I was reading this section all the time when our '06 was new, but when I went back and searched there only seemed to be people complaining and no real solutions to the issue. It really is hard to describe, but it seems to happen when slowing down the most, say when approaching a speed bump. I notice that if you apply the brakes longer ahead of time the clunk is less frequent, but its not like I wait until 3ft before the bump and slam on the brakes (also when decelerating into a slow corner/highway on-ramp).
I experience the same clunk when accelerating, usually when using more throttle than less; again not flooring it or anything too aggressive. One more example where I feel/hear this a lot is when coming home; I have a long narrow driveway w/ a garage at the end that I back into everyday. When I stop and put the car in reverse I get the clunk, but not until I press the throttle slightly. One weird thing is that I notice this clunk more when I have been in the car longer, with more stop and go traffic, in and out of stores etc. I have felt this on our '06, but not to this level
Some may say that I my problem could be solved by being more gentle on the throttle, but in all honesty I think I use it normally. There should be no clunk no matter how aggressive I am.
When I was at the dealer for my 10,000 mile service I mentioned the problem to the tech and they said they would take it for a test ride and report back. They told me that it was under normal operation and that the sound I heard was the DSG transmission going into and out of gear. I do know what they mean about the DSG, but this is a different problem, and if that was the case I wouldn't hear the clunk in instances such as reversing into my driveway.

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.

My 06 FX4 has 106k it started acting up shifting last week and its driving me crazy not knowing what part to change. Sometimes when I take off slowly from a dead stop it shifts really quickly into o/d by the time I am at 15-20mph. Doesn't matter far as hot/cold but if i accelerate quickly it doesn't seem to do it. I have read it could be the Shift solenoid or TPS.

Bought a truck from a guy the other day. Long story, but he was a con artist. Told me the battery was dead from cranking it, he couldn't hear the fuel pump so he thinks it needs a new one. Got it home, checked fpdm, it was unplugged. Plugged it in fp running now. Charged battery. Cranks slowly won't start. Appears the engine has been changed. Have codes P0201-208, all injector codes. Cranking it over reminds me of an older distributor type engine that if off its timing. But also of cranking with a low battery. There's a new starter on it already. I'm going to pull the converter bolts on the weekend to see if they may have bound the torque when they installed the engine. Injector codes?

I have a 2007 F150 XLT with 150K Km. Recently the fuel gauge rises slowly ( 2 start up or 40 minutes of driving ) to the full mark after fill up. The truck is always fueled with Cheveron "regular" gas. What could be the problems ... float, sensor, fuel gauge? and how to check them?

I just had my stock clutch replaced with a South Bend Stage II, of the most recent generation.
It's making a weird noise, and sounds pretty bad... kinda like a rough TDI. It makes the sound when in gear, either accelerating or decelerating. There isn't any noise to speak of at idle.
The sound it makes is kinda like this: [URL]................................
