Add me to the list - getting new cat tomorrow on my EB
I've had the engine stumble from having moist air come through but never got the check engine light. Till yesterday.
Took to dealer. Code was for the catalytic converter. (misfires allowed fuel to get in the cat which roasts them) I've got the original air charge cooler from 2011. They are going to put the big plastic air block on the lower part of the air charge cooler and put a new cat on tomorrow. I imagine the engine power will be dumbed down with the latest ECM update too.
My mileage has been terrible lately and truck has felt like it didn't have power.
Tell me why I have a turbo charged engine if they are dumbing it down??
I'm so happy, not!
I am going to have them check the plugs, possibly replace all of them while I'm there.
My truck has 40,000 miles on it. EcoBoost, the gift that keeps on giving.
If you've never had an issue with your 2011-2012 EcoBoost, you will.
All they will do is install new cats and install the newer air deflector on the CAC. Also I was told by my dealer last year that running ethanol gas was causing the misfire issues and causing the cats to be burnt.
Another thing you can do is Re-gap you're plugs to .030 this will maker her run smoother and all but eliminate the stumbling.
