2011 and 2012 F-150 EcoBoost Loss of Power Fix

2011 Ford F-150 EcoBoost FX2 Burnout

2011 Ford F-150 EcoBoost FX2 Burnout

The Ford 3.5 liter EcoBoost V6 engine in the 2011 and 2012 Ford F-150 had some problems with loss of power (read here for 2013 and 2014 trucks), running rough and experiencing misfires. Only in certain situations, damp humid conditions. There are several other vehicles with this engine as well, such as the Taurus SHO, the Ford Explorer Sport and the Lincoln MKS. These vehicles do not have the same problem, which leads one to believe that the power is unique to the F-150, and you’d be right. It turns out that the root cause of this problem is the intercooler on the F-150 being too efficient, causing a build-up of liquid that then get’s sucked into the engine under hard acceleration. This can cause the truck not to accelerate much at all and in some cases will force it into limp-mode.

There is a Technical Service Bulletin out for this problem, which will be covered under warranty, to have a shield added in front of your intercooler. Yes, that’s all it takes! It takes down the efficiency of the intercooler a notch, preventing the buildup of liquid causing your engine to hesitate/stutter/misfire/stumble. In some cases this TSB calls for the replacement of left-bank catalytic converter. Throughout this process your Adaptive Transmission Shift Strategy will get reset, so shifts may feel different and/or firmer upon completion of this TSB, but that should normalize over time.

This applies to trucks built on 5/24/2012 or before. If it were me I’d want this TSB to be applied to my truck even if I’m not experiencing symptoms, which could simply be because I’m in an area that’s not as prone to this failure. It’s typically caused in damp or wet conditions, under hard acceleration. You never know when you might find yourself in that situation, might as well be prepared! So for those of you with this problem, don’t worry, it’s fixable and it’s simply because a part was over engineered.

UPDATE (2/13/2015): For some of you this TSB still doesn’t completely solve the problem, read more here for possible solutions.

    By the way, WE had the aformationed “fix” of the done “..to have a shield added in front of your intercooler. Yes, that’s all it takes!”…
    WRONG!! It did it again yesterday, yrs after. Now it’s “oh it’s fowled spark plugs”…NOOOO that is from them being burned up by the exessive heat. By the way, they have applied a shield to keep moisture from the intercooler….UH blocking airflow…reducing gas Mileage and performance.

      There are still a number of things to pursue, you could get a catch can, they could also actually be onto something with the spark plugs, perhaps they aren’t properly gapped. I know that the EcoBoost can run roughly when plugs aren’t properly gapped, not all plugs are perfect form the factory.

      IF your problem is just from take-off it could be drive-shaft related, this has been acknowledged by Ford, but there is not yet a TSB, you could get some traction bars to keep it from happening, “it” being stopping the axle from trying to “walk” under the truck”

        Update;
        Stood around the Dealer today for 3 hrs, had a list of things to try changing; ie spark plugs, spark plug caps, remove the lower shield ect. Dealer told us “have to order parts, spark plugs were fine, (no error code) all NOT under Warranty. (Even w/extended 5 yr) cost to do it all $298. For 6 plugs? (I’m in the wrong business.) Plugs = $6.49 When we asked why they didn’t clear the “idiot light” (check engine light) they said “it will clear on it’s own” when we said there was a miss fire of spark plug 1 did they pull it?”  “I think so” when asked: ” was the gap right? What did it look like..” answer: “uh, well he told me but I can’t remember”
        Needless to say we ordered the parts ourselves & will exchange the plugs, caps ect ourselves!
        We went back to Auto Zone (where they tested  for the error & verified the first time plug 1) to do the check again, fowled plug #1 and then cleared the computer. The Dealer thinks we’re mushrooms! Like the options to remedy says “try another Dealer”…other dealer here us 1 hr away but just may be worth the fuel to gain peace of mind.

          That sounds incredibly frustrating. I’d say it’s definitely worth the drive to another dealer. If they are telling you the problem is spark plugs, but then can’t tell you the first thing about the spark plugs in your truck after “servicing” it for 3 hours, sounds to me like they are not up to the standard that they should be, not even close. I think it’s definitely worth getting a second opinion.

            You think? It was Auto Zone who did rge diagnostic test the first time, according to the Dealer that day, they didn’t have the tool to check it with.. Please…so we took that info in yesterday that’s when the run around started. Plugs we are using are Ford Uranium  part SP534 when we asked Dealer what gap should be set at “I’m not sure” Mechanic said between 28-36. On line says Ford has changed gapping 4 times now from high 40’s to the 28-36 it is the gap that is causing the disruption…because so large of a gap (makes sence, since  it’s dumping raw fuel in there & spark has to cross the flow…smaller gap, less distance/ failure to meet) Dealer service akso saud “no need to change plug connections” sute so we can live with carbon build up on those too. .eesh.

            For my EcoBoost I’ve always been told .030. I know that on some earlier models they initially had wider gaps from the factory, but when they came in for replacements/maintenance they were also getting the SP534’s, which to the best of my knowledge should all be .030. Though they are definitely worth checking with a feeler gauge, VERY carefully though since Iridium plugs are very brittle.

            Very concerning that the dealer doesn’t know what the gap should be, that just screams of incompetence as I am sure Ford provides them with everything they need to know. This dealership sounds like it’s worth reporting to the better business bureau and/or its regional manager at Ford.
