2010 F150 XLT FX4 5.4L Crew Cab Medium box, nice blue truck, lacking on chrome though.
My friend has a clunk/lag on take off from a dead stop only. Drives fine down the road, but when taking off from a complete stop, you step on the gas, and nothing happens for a second, feels like it lags, then clunks, gives a jerk, and takes off.
From talking to other newer Ford owners, seems like a common problem.
Ford F-150 (2009-2014) :: Intermittent Chirping Noise When Accelerating From Dead Stop
Intermittent chirping noise when accelerating from a stop. It sounds like a brake chirp but it comes and goes. Not brakes. Changed pads and turned rotors chirp is still there.

I have a 2009 F150 4x4, XLT crew 6.5' bed, 5.4 engine. The truck has a very strange erratic throttle behavior from a dead stop through low speeds, shifting seems very strange at low speeds too.
Dealer tried re-flashing the computer, but that didn't fix it. They talk about some valve that sounds to me like it's similar to an EGR function, but I cant remember what he called this valve. He explained the issue as exhaust gasses that are to be recirculated and burned, but the valve is opening at the wrong time, or stuck open or something so it feeds the fire so to speak.
Does any of this sound typical or common? Is this something that's hopefully easier to do than a spark plug change on a 5.4?
Ford F-150 (2009-2014) :: 2011 - Shudder At Acceleration And When Coming To A Complete Stop
I have had my ecoboost for a couple months now. Overall I am very happy with it but I have noticed a shudder recently when accelerating and when coming to a complete stop at times. I only feel it when accelerating from a stop or when stopping completely. Kind of feels like something slips. I think I recall reading about this before on the 2011 and 2012s somewhere. What is causing this and is there a fix or is it just the way these trucks are?? I can deal with it but it is kind of annoying when driving in traffic.
View 1 RepliesFord - Escort :: 1998 - Getting Bad Acceleration From Dead Stop Mostly?
98 Ford Escort SE
Been having acceleration issues with the Escort for a while now. The repairs I've made on the vehicle so far are; new fuel pump, coil pack and mass air flow sensor cleaning. Those are in order.
Now onto the issue. From a dead stop and sometimes while driving my vehicle will give acceleration issues though mostly from a dead stop. Checked the tranny fluid and it was a light brown with bubbles(?) so thought I'd do a fluid change but with the work required wanted some input before ripping into it.
Ford F-150 (2009-2014) :: Premium Unleaded Gas Increase Fuel Mileage?
I was wondering if one would experience increased fuel mileage &/or power with the 5.0 by using unleaded premium gas, and if so, how much? I know this is true w/ the 6.2L in the F-250, and was wondering if the same applied to the 5.0?

View 2 RepliesFord Super Duty (1999-2016) :: Clunk At Acceleration From A Dead Stop
I have a 2002 F-250 7.3 Powerstroke 4x4. My truck has developed a "clunk" for lack of a better term when accelerating from a dead stop. It is not a shudder as it only happens once within a few seconds of depressing the accelerator and then goes away until the next time I stop moving.
It feels like either something in the drivetrain is not engaging right away, or something is releasing, like a stuck caliper or something. From the way it feels and what I've read so far about the TC/Trans, I'm assuming it is something worn in the drive-shaft/rear diff.
But it needs brakes badly (already have all new rotors & pads ready to install) so maybe a caliper is sticking when depressed and then popping loose under initial acceleration? I think this is unlikely but possible.
Ford Ranger / B-Series :: Odd Sound When Taking Off From A Dead Stop Under Hard Acceleration
Wonder if its dry driveshaft slip splines? Only happens when leaving a dead stop under hard acceleration. Hard to describe sound, but seems to be coming from behind me, almost sounds like 2 broken pieces of steel snapping past each other. frame is o.k., leaf springs are o.k. , doesn't do it when shifting between gears or if I gently take off from a stop. I don't think there's a grease fitting for the driveshaft where the splines are (where the 2 piece shaft takes up slack for being loaded or unloaded) may have to take that apart once the weather breaks and see what i find. my 1st ranger never had this issue after 200K miles. this truck is now at 145K but its almost 20 years old. I've read somewhere before about pulling the shaft apart & greasing the splines up. does this sound like a possibility for whats happening? not sure what else it could be.

So I have had my Platinum for a year now and really love it but there are two things that drive me nuts. First is the range of the romote start, which is the factory installed version. There is no range you pretty much have to right next to the truck for it to work so what is the point? Any way to increase the range?
Second is the audio system, I have the in-dash NAV/Sync system. I use my iPod pretty much all the time. I have it hooked up via USB. Now sometimes when I am listeng to it while driving the turn off the truck do something get back in and stert the truck the iPod does not play, I have to go to the NAV screen and push the USB icon and then it will start to play, other time I just start the truck and it play automatically. I have my system to play automatically but that is not always the case.
Ford 6.7L Power Stroke Diesel :: 2014 - Hesitates From Dead Stop?
I have a 2014 F250 with the 3.55 rear end and 6500 miles and since new it has a hesitation from a dead stop that I cannot determine if it is normal or not. I took it into a dealer that specializes in diesels and they drove it and told me it is normal. Every time I see someone with the 6.7 I ask them if they have the same problem and I get all kinds of explanations from turbo lag to protecting the tranny. The hesitation I feel is when I throttle from a dead stop. It is a very slight hesitation, but very noticeable, almost like a little "dead spot." If I take my foot off the brake and let it take off on its own for just a second or two and then throttle smoothly it is not there at all. If this is not normal, I want to do everything I can to get it fixed. It is driving me nuts.

I have noticed that my car occasionally seems to take off extremely slow from a dead stop? It almost seems as if the traction control is engaging, but I am not taking off fast, and it has also happened at low speeds (10-20 mph)???? It feels like I'm towing a damn boat behind me......
The TSB for the transmission was performed last year sometime.
Prius (2004-09) :: Slow Acceleration At A Dead Stop While Running Only On Battery
The prius stock battery is weak compared to my wifes Mercury Mariner battery. The Mariner acceleration on battery alone is excellent - she can get up to 30 mph in no time on just the battery. In my prius it has very slow acceleration at a dead stop while running only on battery. Is it possible to buy aftermarket (stronger) batteries for the prius so I can at least driver the car up to 30 mph only on battery?

Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.
Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.
Ford F-150 (2009-2014) :: Vibration In Gas Pedal Happens Under Acceleration?
Every once in a while, I'll feel a vibration in the gas pedal. It happens under acceleration, and typically if I'm pushing down and it has not downshifted yet. Then once it downshifts the vibration is less noticeable.
I know there have been issues with the Electronic Throttle Control on these drive-by-wire trucks, particularly on the Super Duty trucks.
Ford F-150 (2009-2014) :: Ticking Noise Under Acceleration Only
I have a 2010 Ford F150 Lariat with 111000 miles on it and now I have a ticking noise under acceleration only and after reading some stuff on here that makes me believe that it is the cam phasers. The question I have is what kind of damage can this cause? Is this something that I can continue running with and does the noise get worse and if so how much worse?

2014 ecoboost Supercrew 4x4 20k miles
It happened at the most inopportune time. I was in the left lane of a two lane road passing a slow truck on a somewhat busy road and it happened. Shudder, loss of power, check engine light on, limp mode. I was next to the cab of the truck when it happened and had to slow and get behind him to pull over and shut it down.
Potentially a dangerous situation.
I rarely step on it, but when I do, I expect it to work.
I baby this truck, almost 18 mpg lifetime average for the 20k miles on this truck.
I took it directly to the dealer to get checked out.
Codes P0305 and P0306.
Checked for carbon tracking on plugs, none found.
Performed a power balance and coil stress test, no problem found.
Removed CAC deflector for inspection, no issues found.
Updated PCM to latest calibration.
