After some comments to both our articles about fixes for 2011-2014 EcoBoost F-150’s that experience a misfire/loss-of-power/shudder/running rough due to liquid building up in the intercooler/CAC, I decided to delve into this further as for some people even those TSB’s aren’t working. There are seperate ones for 2011-2012 F-150’s and 2013-2014 F-150’s equipped with the 3.5 liter EcoBoost V6, so if after having those TSB’s applied you still have trouble, I’ve found 5 possible solutions:

  1. Make sure Spark Plugs are Properly Gapped
    I personally own a 3.5 EcoBoost (in a Taurus SHO) and can speak from experience that having properly gapped spark plugs is crucial for these engines. I think especially for boosted applications it is crucial that your spark plugs be gapped properly. I’ve heard reports of these being gapped as wide as .040″, when they should be .030″. So grab a spark plug gapping tool, like this one (goes up to .040″), or mention it to your dealer. This, in my opinion, could be your most likely culprit for your EcoBoost continuing to show the symptoms mentioned above. The intercooler problems may have been fixed, but improperly gapped plugs could definitely cause the same symptoms.

  2. Get your Intercooler/CAC Replaced
    From browsing through the message board I’ve notice some dealerships have been replacing intercoolers, in many cases this seems to be a successful fix. This could be worth pursuing with your local dealer.
  3. Consider a Catch Can
    I recommend this especially for tuned applications, this can catch any water before it hits your intercooler, just be sure to empty it regularly. I’ve seen this demonstrated on a 2013 Explorer Sport and it seems to work well. This system by RX seems to be favored by many.

  4. Go to a Different Dealer
    In some cases your dealer could simply not be up to the task, or is just drawing  a blank, getting your truck in front of a fresh set of eyes could make all the difference.
  5. Is Your Problem only Occurring on Take-Off?
    In this case you may have an entirely unrelated issue, but the symptoms can feel somewhat the same if/when you gun it off the line. It could be a driveshaft problem and can be remedied with traction bars. I believe this would mostly be a problem in performance/tuned applications.

Do you have any other solutions or are you still having trouble after exploring these options? Let us know in the comments.
