Ford F-150 (2009-2014) :: 2013 FX4 Shifting Into 4wd At Full Throttle On Its Own
Apr 23, 2014
I recently purchased a '13 FX4, i love the truck, the Ecoboost power is incrediable. Recently while passing someone it made a horrible grinding sound, the dealer advised that it was known turbo issue that should have been corrected before we took delivery of the truck. When we took it in the dealer called and said they have Ford corporate involed because when the truck reaches WFO the four wheel drive tries to engage. Said it might be soem sort of vacuum issue.
Specs : 2013 Ecoboost Screw FX4 short bed. No mods, 6500 miles.

Resetting Throttle Response. I came across this video, bored and just playing around, and tried it on my 2013.......and it works! Turn the ignition key to the run position, then slowly press the accelerator pedal to the floor. Then let the pedal up fast, then turn the ignition off. Do this 3 times, and on the last time, also turn the ignition off. I was amazed that that the lagging pedal response was almost completely gone!

I have a 2013 F-150 Lariat 5.0 L, 6 speed auto transmission crew cab truck with 44,000 miles on it. Recently I have experienced problems with the transmission not shifting properly. Three times when I have started out of my driveway, it has shifted into 2nd gear while I am going only 2-3 mph up my driveway which is about a 10-12 degree incline. It stays in 2nd gear even if I stop. When I pull out onto the highway, it shifted normally into the remaining gears. Then, the other night as I was returning home, while traveling up the road, it shifted into 5th gear and stayed there even when it needed to downshift. A wrench i-con appeared on my screen, my odometer showed dash lines instead of mileage and my seatbelt i-con appeared. When I got home, I shut the truck off and restarted it and everything was normal again. I have driven the truck a couple more times with no issues. The transmission shifts normally. Could a sensor be going bad ?

My son has a 2013 Fx4 crew cab 4X4 ecoboost with 8500 miles. He says in the morning for the first couple of miles while accelerating gradually the trucks shudders when shifting gears. After a few miles it goes away. Dealer says they can't do anything endless he can duplicate the condition. He went out of town for a few days and left me the truck so I'll drive it in the morning and see what it does.

96 F150 carbed 300 with a C6/208 SAS44/9" with 3.55 on 35s.
I put a transgo shift kit in the transmission before putting it in the truck, it also has a small stall. At half throttle you can manually shift 1-2-3 with no issue at all. Under full throttle when you shift to second it won't go into second until you push the shifter into third. Then it'll go to second and spin the tires when it grabs second in dirt. This is all in 4lo, I was gonna switch to 2hi and try it but it's raining and I don't feel like crawling under it to change it. The truck is a mud toy so will spend 90% of its time in 4lo.
I don't have a vacuum line currently hooked to the transmission because I have the same shiftkit (transgo) in my 77 and no vacuum line on it either and it works fine.

2012 F-150 ecoboost oil level rising up to 1 qt over full. Took it to the dealer, They are installing a block heater and a new vent line. Cannot see what a block heater is going to do for me in a warm climate. I will let them do there thing and see what happens. 24,000 mils on the truck and warranty runs out in Dec 2015.

From everything I have read I can't seem to figure out exactly what the fix is for what feels like brakes sticking after coming to a full stop, then accelerating? I will describe as a clunking and kicking feel, as if power to the rear end is being delayed then kicking in.
From all the posts and replies it seems like a differential issue. Exactly what the issue is and the correct fix? 2012 purchased used with less than 5K miles in 2013, problem has slowly been getting worse over time.

Title says it all come to a stop, step on throttle nothing, let off and step on it again it goes, does some one have to be killed before Ford knows there's a problem, it's happened to me 3 or 4 times in the last month, dealer checked said there's no codes so nothing wrong. OK I forgot the good info 2014 eco screw 4X4.

My R is vibrating in second gear near full or full throttle around 2,000 Rpm. It feels like a high frequency vibration. It seems to be only happening in that scenario. It's when the turbo spools up and there is a large rush of exhaust gas produced very quickly. My guess is that my apr downpipe paired to the stock cat back is the culprit. It didn't happen when I first put the downpipe on, but after the next track day it started. I don't know if there is anything to burn in inside the apr downpipe but it got louder too. Could it be back pressure from the stock cat back? It's very strange and I wondered if it is stage 2+ but running the stock cat back has felt this? I checked to see if the drive shaft was rubbing on anything and for any other visual indicators of rubbing around the downpipe and I see nothing. Perhaps it's the stock muffler. I'm just not sure.

Experiencing sluggish throttle response on the EFI Ecoboost? I have had several incidents where I'm needing to change lanes fast and the response is a dead second or two before the motor catches up to the throttle position. Then, it rockets forward at full throttle to catch up. By that time it's too late to change lanes and I have to be on the brakes hard to keep from rear ending the guy in front of me. I'm coming from a carburetored Toyota Tacoma that was far more responsive (minus the power) then this truck. I never felt hesitant to jump on it and go. Now I feel like my life depends on waiting until I have all day to change lanes, make a left turn or pass a slow moving vehicle on a two lane road. Is this something the dealer can adjust?

I have a 2014 F150 ecoboost with a 3 inch lift and 33 inch tires. It seems that in every gear minus 6th that when I shift it shifts to normal RPMs then the truck sort of bogs down, losing 300 or so RPM, then keeps going like nothing ever happened. There are 58,XXX miles on the vehicle. I have taken it to Ford multiple times, now they are saying I probably need an aftermarket tuner to take care of the issue because of the bigger tires.

I have a 2011 f150. I go to put it in reverse no problem after I'm done backing up and put it in drive. The truck does not go anywhere but it will race up to about 4000 rpm without even having my foot on the throttle. Put in park then back into drive same thing happens. Put it back into park turn the truck off start it again and no problems. It drives just fine. I've had it to the dealer they say it is not throwing any codes so there is nothing they can do about it.

I just picked up my new 2011 F150 SCrew with Ecoboost on friday (pictures soon). I noticed after driving it a little, there is a noticeable burning smell...almost like an oil smell. It is even more noticeable after I had been driving with a little more throttle.. i.e. getting the turbos working a little. I attribute this to the normal coatings of oils on the parts but it still is a little concerning at times. I'm sure I'm worried about nothing and this is normal...

For the last few months my truck shifts rough between 2e and 3e gear. However it only does this first thing in the morning, when I leave the house I speed up until the end of the street, then when I let go of the gas it'll rev up a bit and shift from 2e to 3e while making a big clunking noise which I can definitely feel ...
It does it sometimes very rough and sometimes just a little bit. I used to not worry about it but i'm starting to wonder if something is wrong with my trans. Could it have something to do with the slip yoke?

Used to own a F250 so I am new to the F150. I am currently in a 2014 F150 fx4 with about 10k miles on it. I noticed when the truck is shifting into 3rd (normal acceleration)the rpms once in third remain around 1800 then drop to 1400ish after about 2 seconds or so while still in third (almost like its shifting again). What it is?

I bought a 2009 f150 5.4 with 150000 miles on it. I have a slight hesitation from idle so I want to clean the throttle body. I found several for the older f150"s with the horizontal throttle body but this 2009 has a vertical mounted one. I change the air filter and cleaned the MAF but didn't change anything. My wife's ford 500 had this problem and cleaning the throttle body completely cured it.

Having issues with the vacuum falling off to the hubs when driving and light throttle. I know makes no sense,but kept fighting this thing making vary harsh rubbing sound since I bought it used and I know its the little collar on the back side of hub that engages to hub to make the 4x4 connection but it looses vacuum when driving and very light throttle/load.
I verified using a vacuum gauge ran inside vehicle when driving. Checked all lines and hubs,everything good. Solenoid has vacuum when running but seems to quit when light load or throttle and as soon as vacuum falls off then the collar starts to engage and rubs but doesn't fully engage. I don't get it. Unless there's something on the computer side of it shutting off the solenoid or something.

I just picked up my 2011 FX4 Ecoboost with the 4.10 axle ratio. While in drive, the transmission will not shift into 6th gear until around 65mph. The rpms in 5th gear at this point are around 2300(ish). If driven with Tow/Haul mode on it will shift into 6th at 45mph and lock the converter. If traveling at a speed in drive (no T/H) where you would think it would be in 6th, lets say 50mph on flat ground, and you force the trans into 6th, either by using manual mode or T/H, and then return the transmission to normal drive mode it WILL hold 6th just fine with the converter locked and will even accelerate holding 6th.
If you accelerate more rapidly and the transmission downshifts, it will not return to 6th until forcing it to do so by one of the two ways above. I realize that the truck has adaptive learning strategies, but this doesn't seem right. It also has only 300 miles. Initially I had even thought that this might be some sort of break-in programming, but not anymore.

I have 2012 F150 5.0. Was going to do some errands yesterday. Got 3 miles from my house and all of a sudden the transmission would shift from say 5th gear down to 2nd. Then it would shift up to 6th then back down to 3rd. It was shifting all over the place. I did shift it to manual it seemed to stop it a little. But then it would shift by itself again .I went directly to the nearest Ford dealer. I did not shut it off, so if there was a code there they would see it... No codes. The Ford dealer will look at it. Any thoughts?

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?
