Good news, thank you. Did you have the misfire type feeling when adding a load to the engine? And did it fix that?

I wouldn't call it a misfire issue so much as a fall on it's face issue. There was no power when it happened in the past.

Has it fixed this issue? I don't know. I've only been in similar conditions four times now to try it. I need to be in similar conditions and drive a bit further to really test it.

Sorry don't have time to read all 53 pages but still felt i should share my experience on the Ecoboost issues. I am currently at the 75,000 km mark with my truck and I had to take it in to get "the fix". Immediately after getting the PCM update and having the upper portion of the intercooler blocked I left for a 3000 km trip.
I thought I had the problem before the fix, now I know I have the "problem". It was terrible.
Brought it back to Ford and they installed yet another PCM update and said they have ordered some parts. I left and almost immediatley the check engine light came on. Ran like a dog.
Parts came in and it turned out to be an updated intercooler (complete unit) and they also realized the water had killed the catalytic converter so they had to order a new one. The next day they called and said that the truck was done but was still running rough. try it out and see if it clears itself up is what I was told. They asked me what I ran for fuel and if I idled it alot..... NO. And only top teir fuel with premium (91 octane) since new with exception of the last few tanks being regular. When i asked why they asked such questions, they explained that they were just wondering if maybe the spark plugs were maybe needing an early change.
I asked them to keep it another day and change the plugs and since they were going to be in there to check the coils as well.
Sure enough they had to replace the #2 coil.
All was free of charge with exception of the spark plugs as i requested new ones.

Runs like new! Unfortunately, they don't readily offer the fixes, you might have to push a bit. If you ask for something to be changed, chances are you'll also be paying for it.

One of the guys I work with has a 2012 FX4 SCREW and is having the same problems mine has but only at 35,000 kms. He has an hour and twenty minute commute each way to work so I'm assuming that its also water build up. the reason i mention this is so people know it isn't just the 2011's that have the problem as I have read in a couple forums.

I still love the truck, but beware if you're just getting into one or buying a used one.

I will update if the problems come back, hopefully I never need to do that though.

Thanks, just wondering as I have had the total loss of power on hard acceleration...but also have the misfire issue when adding a load to the engine, like when going up a hill with the cruise control set.

I am new to the forum and love all the information on the site. When this condition occurs it sounds like some of the people are not setting a code. JDOGERTYs datalog shows the ETC closing immediatly after a heavy throttle input. Do u guys know what conditions can cause the ECU to overide throttle input and not set a code. (Speed limiter, Traction control Torque Management) Just curious if some of these issues could be related to some kind of ECU control function.

I've had what I would consider a misfire or stutter while traveling uphill. However I honestly haven't paid attention to whether I've had it since. I would tend to believe the stutter would be related more to spark than the CAC. I do need to pull my plugs and check/regap if necessary.

I agree with you , mine does the same thing . I believe it is knock retard causing the timing to pull out giving the stutter feel. I tune with HP TUNERS on the older ford trucks and mustangs. When knock retard happens it feels exactly the way my truck feels. JDOGERTYs data log reveals the ECU is pulling lots of timing out erratically before his vehicle goes into limp mode.

Any ideas as to why this phenomena only happens at 55 degrees or less(on my truck at least)? All Winter it did it...soon as it warmed up...it was gone all Summer. Back in September when it started cooling off...it would do it in the mornings when below 55 degrees...in the afternoon on the way home from work after it warmed up...on the same hill...it would not do it?

Could it be that the cooler it gets the denser the air, making the engine run leaner? When it's warmer the air is less dense making the engin run richer? Maybe what ever controls the air/fuei ratio is not working properly. Back in the day we had chokes on the carbs to help with the cold weather starts. Just saying. I admit I don't know much about these new turbo/ DI engines. Hope you get it fixed. Have a great holiday season.

The way I see it...more often than not the dew point is a lower number...so in the 50s and below your closer. Such as usually when its colder its usually foggier than in the hotter months.
