Ford F-150 (2009-2014) :: Eco Boost Turbos Cycling On And Off During Acceleration
Jan 8, 2012
I have a 2011 SCREW (build date late April) where the turbos started cycling on and off during acceleration or under load when pulling a trailer or going into a strong head wind. It started at about 18,000 miles and I brought it in to the dealer. They road tested it and could not duplicate. It continued doing it and I had a dealer tech ride with me at the next oil change. He confirmed the problem...this was around 22,000 miles.
Dealership contacted Ford and although they were aware of it (something to do with opening and closing of waste gates if that makes sense) they did not have a fix. They said to check back after the holidays. Since then it has gotten worse cycling on and off under a lesser load. The dealership checked again two days ago with Ford and still no solution but they thought the eventual fix would be to re-flash the computer.

New here, faithful f150 owner. Recently bought my first new f150, a 2011 supercab xlt 4x4 ecoboost. So far I've managed to put on 5600miles. I love the truck, but have noticed a few things.
1. Granted its a 4x4, but I have yet to see hwy mpg above 17.5 in 2 hi.
2. I can hear one of the turbos spooling up and stalling. Sometimes it'll happen at idle when stopped...Is this a common occurrence?

Take delivery of my new F-150 tomorrow. Was wondering if there is any particular way to break these motors in.

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.

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.

I have about 22,000 miles on the odometer. I bought it as a CPO with 2200 miles on it. Truck is all stock.
I have heard this noise only once before. I will accelerate up to about 45mph, back off to about 30-35 possibly less, then accelerate again. When I do, it downshifts and I hear a lout noise that sounds like a yelp a dog would make if startled.

15k on my Platinum, love the truck. I've had a handful of chimes and flashes of something on the productivity screen, most recent on an acceleration, pretty good, no WOT, but 2/3 or so, hear the chime and see the orange box on the screen, but it is gone before I can see any text etc.
Oil level good, 10% til next change. possible tire sensor? Never had a TPMS prompt. Have noticed it has only been when the outside temp is around 30 degrees F, or lower.

My 2012 3.5 ecoboost has a knock and power lag during acceleration. Dealer diagnosed as timing chain and cam shaft phasers. I asked if this was common and they said, "yes, it will happen to all of them at some point." Basically, he said if you baby the truck it will take longer, but still happen. Wasn't surprised I'm having it at 67k miles as he saw another recently at 70k. The power drop is dramatic, so I don't see any option, but to have the work done.

Start from the beginning 2011 screw 4X4 ecoboost 46,000 miles, under wide open throttle and over 3,500 rpm I'm getting a misfire, diagnosis "I usually chicken out when I hit 80+ in 3rd". Misfire occurs in 1st, 2nd, and 3rd don't have enough road to try a higher speed or gear.

I have an 09 F150 4x4 with 116,000 miles on the clock. I am having an issue with moderate acceleration and felt mostly in 3rd gear. I changed the spark plugs at 106,000 miles with OEM replacements. I have had this issue since about 80,000 miles but intermittently. It seems its starting to get worse as time goes by. The problem is both cold or warm and doesn't happen all the time but now about 80%. Light acceleration is good and full acceleration is great with no issues.
Feels more like running out of fuel but not to the point of stumbling. Possible misfire that is not being detected. No check engine light lit. Tranny shifts perfect. Idles extremely smooth. I was thinking a coil problem but with no engine light, I don't want to try to guess which one. So far, this truck has been awesome and has needed nothing but tires and routine maintenance. I pull trailers consistently and this beast is not abused nor babied.

I picked up a 2014 F150 with the EcoBoost engine a couple weeks back and while so far I love it, I can't get over how quiet it is. So, to my question, has anyone done anything with the exhaust to get some of that truck sound back. A slight rumble on acceleration would be nice to have and maybe get some gains out of it, but thats minimal.

Was driving to Airport yesterday and out of nowhere got the flashing check engine and shudder/limp mode while trying to merge/accelerate onto the onramp (had to gun it to go around someone who decided to stop on the onramp for no reason). Let off the gas and the blinking went away. Upon leaving the airport I was accelerating again at highway speed to pass and got the blinking light and then a solid CEL. Found my way to a Autozone and got the code read. P0301 Cylinder#1 Misfire. Was suggested to change COP and plug.
Changed COP on the spot and had to drive it home to my tools to install plug. Thought maybe that since the CEL was still on solid after changing that the code needed to be cleared for the PCM to function normally again. Still have shudder when accelerating hard, so thought it might have been injectors so got cleaning service done at Goodyear. Still have the issue. Disconnected battery and performed IDLE relearn just now and it still is shuddering upon hard acceleration. Stumbled across TSB 12-6-4 which speaks to my symptoms.......I do not have the plate which in turn would imply I do not have the PCM update it references.
I have not noticed a misfire nor had an acceleration issue before so this was a surprise to come out of nowhere. I'm going to be calling my dealership in the morning.

I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.

Have a ecoboost that moans and groans under light acceleration ? I asked the dealer about it and he said everything was fine. I guess its the turbo blow off valve. It run fine, just weird noises under the hood.

I took my 2011 Lariat in for first service and reported that it sometimes tries to accelerate on its own during slowdown from high speed, eg when coming off a freeway ramp, rpms go up and vehicle wants to speed up rather than slow down. (sounds like something a Toyota would do!)
Dealer says its a known problem with 5.0L and performed a supposed fix per "TSB 11-8-9, 5.0L ENGINE BRAKING PERFORMANCE DURING LOW SPEED COAST DOWN," essentially a PCM reflash.
Happened once in a parking lot...thought the floormat was stuck on the accelerator but the pedal was clear.

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.

So today I had a scenario where I had to pull out from a blind corner onto busy street. By the time I pulled out I realized an SUV was coming down the street fairly quickly. My immediate instinct knowing I have 360hp on tap was to put the hammer down.
I basically planted my right foot to the floor and held it there. The truck was already rolling out of the lot and turning into the street at approximately 5-7 mph. This resulted in the truck shifting hard from rolling in 2nd gear, down to 1st. I never drive this way so what I'm asking next is if this is normal or not. As I held my foot to the floor through 2nd & 3rd gears the truck seemed to blip the throttle at 4k then up-shifted from 1st to 2nd gear.
I have a stock Ford Raptor exhaust on my truck with the resonator deleted and when the truck blipped the throttle just prior to the up shift, the exhaust "popped" like a race car with an open exhaust downshifting from speed into an apex. Yes it sounded cool, but it was obviously cutting fuel or throttle for some reason.
So here is the weird part, out of curiosity I tried a few different scenarios just to see if something was wrong with my truck. *Note if I just mash the gas from a dead stop there is no fuel cut going from 1st - 2nd gears at WOT. The fuel cut only happens when I'm leaving out and getting on the gas from a turn.
If I turn off the traction control or advance trac and stability program then there is no fuel cut or 4k rpm, the truck just runs out to the 5600 or so redline seamlessly. Im just wondering if the traction control or torque management is really that sensitive or aggressive? I mean it was 70 degrees out and the road dry, plus I was already at a speed 45-50?? mph where a loss of traction would not be an issue so what gives?

I have a 2013 F150 3.5L Ecoboost XLT and have recently experienced a slight noise on acceleration in first gear. Sounds like a light rattle or ping. The dealer says it may be due to carbon buildup (I have noticed that the exhaust has a lot of soot on it). They are suggesting some additive to resolve this and she mentioned that the problem starts to show up at about 30,000kms. It does not affect power or cause misfire as described in posts.

Trans Noise At least I think it’s coming for the trans. Ok here it goes. When I’m just taking off at light acceleration going through the gears I hear what I call a humming noise. It starts off low and as you increase rpms to the shift point it get louder and then start over again. It does this in most of the lower gears, at least what I can hear. As you get going faster there is more wind and tire noise, so I can’t hear it as well. I have heard it at higher speed but conditions have to be right. I found a YouTube vid that someone posted. It has the same noise I’m talking about, he did a great job recorded it. I tried but didn’t have any luck. Anyway he took it to the dealer and they say it was a the separator plate. His is fixed. I did hear that there is a TSB on the Trans for the separator plate but not sure if it is for the same problem I’m having.

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.
