Nope, actually proves it. We have a very humid climate.

didn't know Canada would have that much humidity as compared to Florida or southern states. Learn something new each day..

Keep in mind it's relative humidity. Rainy day humidity is 100% and all parts of the world get rain eventually and foggy days humidity is up. Some areas are just typically more humid than others.

Also this is getting mixed up as there are really at least two different issues being spoke about here, technically 3 and my basic understanding.

Issue 1 - Limp Mode aka loss of power which seems to be more so related to the condensation (higher humidity) issue.

Issue 2 - the Shuddering - unless you put a tool on it to verify a miss you may just be having the shuddering issue and mistake it as a miss. I have had the shuddering issue, but what it actually seems to be caused by is the boost building up too much pressure and then the blow off letting it out, so it shudders/surges. Downshift as soon as you notice it and it'll go away. If it happens again in 5th then downshift one more time. I've never had it happen in 4th to date.

Issue 3 - the Miss, verified with an OBD tool - a cylinder/more is not firing correctly, cracked spark plug, gap too wide and boost blowing out spark, faulty coil pack, faulty wire, etc.

True, but there all related to the Ecoboost engine design. Has Ford moved on and focused on the 15 model and how can they put this same engine in. Would all the current and past EB owners effected by these issues buy another EB. Even if they didn't have an issue would they take that risk in another 1st year model..We will see.

The only common factor here that I am seeing is the ecoboost engine design in a truck and only some trucks.

The torque, power and fuel mileage they are getting out of these is incredible - http://www.autoblog.com/2013/09/17/f...oboost-engine/

no doubt, I am not knocking the engine, it is a great low torque, decent fuel econ engine,, it is fun to drive but if you were to take away the IC issue it would be a perfect engine, assuming it is reliable and not riddled with part breakdowns.

Is the ecoboost engine in the truck the same one running in passenger cars? Just wondering if you took the ecoboost engine that experienced the limp/shudder and then placed it in a Taurus would it replicate the issue in the car. Excuse my ignorance.....just wondering why we have not heard of a passenger car with ecoboost possibly pulling a small trailer or boat having the issue in rain or wet conditions.

Truck owner

they had issues with there 1.6L ecoboost in there cars but don't think is was same issue as trucks. I think this EB is a great engine, even if it doesn't get the fuel econ as advertised. Its smooth, powerful, and just darn fun to drive and even Wow! factor when I choose to get a idiot Chevy/Ram driver off my tail and watch my truck separate from them and you see there trying to keep up..I got the Maxtow and the 3.73 really makes this truck. I had a issue with a misfire under load in 6th gear and the TSB took care of that. I know if I mod anything my mileage will get worse and I am not interested in getting 13-14 mpgs in this truck..

Had my cac replaced about a year ago and still had the misses...occasionally. This morning in warm 50 degree air, accelerating up a highway on ramp, it did it again and this time threw a code. Called my service manager and drove right there so he could read it. Code was for random misfire I was told. At this point I'm feeding all the info I can to my service manager. His hands are tied as ford directs all his actions in EB. He did mention there may be another reprogram. Taking the lead EB mechanic kc for a ride to the on ramp where I can repeat the shudder consistently on Friday. Will keep the group updated

I can make it happen at will in 4th also. Set cruise at 30 MPH and head up this little incline with a 30mph speed limit and it will shudder all the way to the top.
