Ford F-150 (2009-2014) :: 2011 F250 - RPMs Drops And Then Shut Off?
Jun 29, 2013
I have a 2011 F250 6.2L Was working great until the other day when I went to hit the gas and the RPMs dropped and the truck shut off. I tried to restart which it would do for maybe a second and then shut down again. I checked the fuel line going to the top of the engine with the key switch on and there was not very good fuel pressure. so I thought my fuel pump was bad. After switching the fuel pump, the truck still starts and immediately shuts off. I checked the fuel line again and this time it is giving an initial burst of fuel for a second and then nothing. What else it could be?

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 traded in my 2011 Lariat last month because I had quite a bit of problems with it in the short time I had it. I also didn't care as much for the bells and whistles as I thought I would when I bought it.
I got such a good deal on a new 2011 Lariat Super Crew, that I traded. Shortly after getting the new truck, I had to take it to the dealer for two dents that I found the first time I washed it. I didn't see them when I took delivery because it was dark. I had not seen the truck before that because they got it from another dealer to get the color I wanted. I also had problems with the radio buttons on my steering wheel and the sirius button on the dash not working at times, damaged trim around the left side of the windshield, a discoloration the size of a nickel on the console that I noticed when taking delivery, and a ticking noise in the engine . After the truck was in the shop for 3 days, I get it back without anything being corrected. Parts had to be ordered for the console and trim piece.
I took the truck back in 10 days ago for the engine noise and for them to repair the dents that were there when I got it, along with more troubleshooting on my intermittent problems with the radio and steering wheel buttons. I get a call late yesterday afternoon with the verdict.....Ford says replace the engine due to something being wrong with the crankshaft.
I have to say, I'm pretty disgusted right now. I'm not so sure that I want this truck anymore because of all the issues I've had in the short time I've owned it. Service department at the dealer has been great, and the dealership has been talking about possibly getting me into a new truck. I'm just not so sure I want to try a a third truck. I've been a Ford man my entire life, but I'm disgusted with them right now. I certainly don't want a Chevy or a Dodge, so I don't know what I'm going to do at this point.

I have recently purchased a 2011 F150 Ext cab with 3.5L ecoboost with 69k miles. I have no experience with these engines prior to now. I've always wanted a full size truck and after driving my 98 S10 for 17 years, I decided it was time for a new truck. I hope I made the right choice in going for the 3.5 instead of 5.0.
On to my question. I've noticed that the truck hesitates from a dead stop or anytime the RPM's are under 1k. It feels like its missing or running lean/rich during the spin up of RPM's. When I drive it hard, it does seem to subside for a little, and I've heard people say that they run better when run hard. I can attest to that, but is this hesitation normal for an almost 70k mile engine? I am getting 15ish MPG on almost all city driving since I have bought it, but I do expect that to change (job hunting and current commute is less than 2 miles each way).
The only time I get to open it up is when I go run errands out of the immediate local area or visiting friends and family. On one of those trips, before I noticed the hesitation, I attempted to accelerate from 60 to pass on the expressway and it bucked and resisted like a horse. It finally took off up to 80 and completed that journey with no issue but the check engine light came on for a bit. The check engine light went off when I shut it down and hasn't come back on since.
New ride: 2011 3.5L Ecoboost....

Our summers typically hover in the 90's and the winters in the 40's. Each year we typically get a good cols snap and it drops in the teens at night and 20's-30's during the day.
Earlier this winter we had a week long episode of colder than normal weather which hung in the low 30's all day and teens at night.
The avg MPG's on my truck for mixed driving dropped from the 18+ that I normally enjoy to around 16.5. When the weather returned to normal for us, my MPG's returned to normal as well.
Have any of you noticed any serious climatic swings in your MPG's?
Yes, I know that vehicles normally burn more fuel in the winter but the info screen on my truck drives that point home.

2010 F150 5.4V8... At altitudes 9000 ft and above the engine RPM rises and drops while at idle and while driving slow. It also burns more gas.

My wife and mom went to the dealership today to get remote start installed on their F-150's (bad decision not to do it from the factory). Both trucks had it installed, and it starts the truck fine, but the problem is as soon as they put the key in the ignition to turn it to "Run", the truck shuts off and they have to restart it. The tech says thats "Normal", and it's because of the "My Key" feature.
Neither of the trucks have had any of the keys set up to be "My Keys", all are exactly how they are from the factory. Something doesn't seem right....

This is not on our F150, but rather our Flex that has the 3.5 Ecoboost.
Recently we have been having a bucking problem at lower rpms. Usually when taking off and hitting a slight grade. Doesn't really have a problem at highway speeds. Usually only on takeoff when it shifts through the gears. If you accelerate more, you can stop it for the moment. Weather doesn't make a difference. Also can feel a slighting surging sometimes and can see it on the tack. Like a 2 sec alternating surge. Doesn't do this all the time though. I have replaced plugs with iridium, gapped at 34.
I also purchased two motorcraft coil packs and installed them in different configurations as to see if I could isolate it. No change. I HAVE NO CEL YET. At all. Wish it would! I have tried to make it buck hard enough to throw the code to no avail. I have heard of condensation in the intercooler, but from what I have read it is a higher RPM symptom..This feels just like the COP problem on my 5.4. Unless I have 3 or 4 bad COPS and no CEL. If I could just get a code.

First week or so, the alarm was fine. It would go off if the passenger didn't have their belt on. Suddenly, it wouldn't shut off, even after the passenger put their seatbelt on. We went through the procedure to just disable it. It worked for a couple days.
Then it started going off again. It only happens if I have a passenger in the front seat. (I have two children in the back but they are in carseats and if it is just them and I, we have no problems, but if my husband is in the passenger seat - we have problems).
We went through the procedure to disable it and it didn't work this time. After more reading I realized the same procedure to disable it, enables it, too - sooo we did it a 3rd time to disable it, again. It worked.
Same trip, we got back in the car -everyone is buckled up and IT GOES OFF AGAIN!! I just want it disabled, period. It drives me crazy.
(It will stop dinging about 10 minutes into the drive but most my trips are under 10 minutes so that means all the time)

Basically, when I just cruise in say 6th gear, and then step a little on the gas (or there is a hill), the engine rpm's jump up by like maybe 500 rpm's without a noticeable increase in speed, and there is no downshifting either.
I am sure this is normal, right? So what is the transmission doing? Coming from manuals only in the past, this seems strange.

We currently have a 2011 F250. During the day time, when you turn on the headlights all the way (not just on "auto"), the dash lights and clock shut off. Originally, I thought that they were just dimmed to the point where you couldn't see them, but the brightness is already turned all the way up on the dash lights. If I turn the brightness up any higher, the dome lights turn on, but the dash and clock remain off. If you return the headlights back to the "off" or "auto" position, the clock and dash return to their normal brightness.

My radio stopped working on my way to work. I heard a loud "pop" of static and then it shut off. I took it to the dealer, which had a hard time fixing it (they had it about 2 weeks), and they replaced all the fuses in the truck and it worked for about a week, but it just stopped again. Not sure what to do.

I just purchased my brand new 2014 F150 4x4 STX 5.0L single cab short box about a month ago. I noticed when I drove it off the lot that it had a slight vibration at low RPMs. I boiled it down to brand new stuff working out all the kinks and running around for the first time, bought a brand new jeep in 2005 and it made interesting noises and had funny vibrations for a while, but this is starting to get annoying. I have a very noticeable vibration at low RPMs both in park and while driving, more noticeable at speeds between 35-45 with RPMs anywhere from idle to 1500 or so.
I have not had it at the dealer yet, I want to be armed with a little bit of knowledge when I go in an talk to them if possible. I know how stealerships work and since it seems similar problems are somewhat common in these newer F150s, I don't want to get the "oh it's common in these trucks and perfectly normal". In my opinion a brand new truck should run smoother than melted butter on hot flapjacks, especially one that only has 1400 miles on it.

I recently noticed my brand new truck with 5k miles has been making a humming /vibrating noise when shifting and when RpMs are above 2k. What this could be? It's a 2014 F150 stx 3.7 ....

The 6 button powercode remote start and alarm will shut the engine down if you open the door after remote starting.
Here is the fix, I found it somewhere else. It's nice doing stuff yourself that the dealer tells you it cant be done.
open the drivers door
turn on the ignition
hold the program/override button for 15 sec (horn will chirp 3 times)
press the override button again horn will chirp 4 times
" " horn will chirp 5 times
" " horn will chirp 6 times
" " horn will chirp 7 times
" " horn will chirp 8 times letting you know you are in option bank 5.
press the panic button on the fob horn will chirp once
" " chirp twice
" " chirp three times
" " chirp 4 times
" " chirp 5 times
press the lock button on the fob once...your led alarm light will now be off.
Turn off the ignition
you are done
Enjoy
Activate the remote start open the door(smile) just don't press the brake before you put key in ignition and turn.

2010 F150 ... So I have the tick noise at rpm's 800-1000 at drive through, stops, etc. So I did research on it a few months ago and saw that it might be VCT's but should be able to drive. so I drove it waiting to save money and have it go to a shop. well this past weekend while coming home from work my oil light came on the pressure dropped to zero, I was on the highway so I drove about another mile to get off highway and once I got off my truck died. I had it towed to my house and I thought I blew my motor. So I started doing research here and found that the VCT's AND cam Phaser could be bad. so I replaced my VCT on driver side put it all back together it started and loud knock was gone. then after 5 mins it was back very loud knock!
So I shut it down and took apart the passenger side once I got the valve cover off I found the problem.... The bolt that holds the cam phaser in place snapped off and was riding along the camshaft. So I took that out and extracted remaining part of bolt. inspected my camshaft and it was really messed up. so I bought new Phaser and Camshaft. the camshaft just came in today and I am trying to put it back in. but the hole for the pin in the phaser doesn't line up and I cant spin the shaft to make it line up. should I spin the cam phaser? I marked the chain and the phaser is where it should be on chain, but with that bolt snapping off could that have thrown the timing off so my mark is no good? when I lay the camshaft in place it sits perfect and if I just move the phase over 2-3 links it will all fit together. Should I do that?

I have a 2012 4x4 EB CC. In 6th gear, on the highway between 1200-1700 RPM's, during a slow acceleration, it feels like it is missing or shuddering. It is most pronounced going up a hill, and/or towing something. As soon as you get above about 1700, it goes away. Rig needs to be fully warmed up (not just the engine, but tranny/drivetrain). Needless to say, this is generally from about 52-65 mph, which is most highway (not freeway) driving I do. At times it's so bad my wife says it's time to get a Chebby.
Had it in about a year ago, couldn't duplicate it. Took it in this last week. Did the TSB on the plugs, and was told that would fix it. It didn't. Took it back in; they couldn't duplicate the issue. Rotated the tires hoping that might do something. Took the head service guy for a ride, and made it happen; it was very obvious then. It seems like the tachometer should bounce or shudder a bit when it's doing it, but nothing. It's going back in on Monday to see what they can do.

My 2011 3.7 CC seems like it is missing at speed.
If I am around 75 or so in 6th is vibrates, but downshifting to 5th or 4th seem to take it away.
I am going in tomorrow and have the tires rotated and balance, but I think it is somewhere else. It has a little over 42,000 miles
