This morning I noticed about a pint sized puddle of something under my truck. I backed it out of the garage onto the drive way to warm up and found the puddle on the garage floor to be water. My driveway has a pretty good incline and when my son came out to leave with me he pointed out something was leaking under the truck. Sure enough it was water, dripping down directly from the exhaust cross over pipe that connects the 2 exhaust banks. It was dripping at a pretty good pace. Seems I have a significant amount of water in my exhaust? Is this common? I realize condensation forms in exhaust and I've seen water drip a little water out the exhaust on other vehicles however this seems signficant and the puddle in the garage leaked out sometime between driving the truck home 2 days ago and parking it. It hasn't been driven since. Ironically the last time I drove it was when I picked it up at the dealer after having the 12-10-2 flash done.
I havent had a flash done and mine does the same thing.

Did a run to my cabin Friday morning to sheetrock/insulate the garage and came back Saturday afternoon.
Friday morning when I left home, it was mid 50's. Humidity was high, and there were some light rain showers over the 145 mile drive to my cabin. Temp dropped to the mid 40's about halfway through the trip and stayed there.
Approx 60 miles driven at 72 mph, 85 miles at 62 mph. Towards the end of the trip as you near my cabin, it starts to get hilly, and the miss was definately still there going uphill. Not as bad as before, but it really wasn't that cold either, which affects when I feel it. I had the TSB done about 2 weeks ago. At the end of the trip, I attempted to get the truck to fall on its face by pulling off the main road and gunning it. Surprised it didn't happen, but thinking maybe going up those hills towards the end of the trip forced enough water out of the system to prevent it from falling flat. Ending mpg was 20.2 mpg for the way up.
On the way home Saturday, temps were around 70 degrees, light winds. On the first stretch of 85 miles at 62 mph, the shudder was not felt at all and I averaged 21.3 mpg. Right at EPA estimated highway mpg. Once I was up to 72 mph the final 60 miles I was getting more around 19 mpg. Ended the 290 mile trip with a 20.2 mpg average. Not too bad for one of the worst mpg configurations possible, just wish I could get that a little more consistently.
Putting a call in to my dealer to let him know shudder is still there and to keep me posted of fixes.

My '11 with the 5.0 has a bad miss feel in the engine when towing my boat. I don't notice it at all when not towing, but when under a load, it's awful.
On a side note. I still have yet to see one sitting on the side of the road broken down. I can see with the last few posts that now people are starting to get paranoid about everything they can think of.
To be honest, this was the biggest reason I chose the 5.0 over the EB to begin with. I just didn't know enough about the new engine to be comfortable with it, and these posts show others don't either.

Towed a small 4'x9' U-haul trailer with a motorcycle on it last weekend and mine did the same exact thing..... Took it to the dealership and they claimed the coil on #6 cyl was weak (per computer) so they replaced it along with the spark plug. Haven't towed anything yet since I don't own a trailer. Hoping it cured the problem but I'm don't feel confident about. Keeping my fingers crossed.

Just completed the two day round trip to Dallas and Back. On each day of travel we passed through a different weather event. The weather events that cause the burdensome condensation in the intercooler.
The affects can very all over the place and begin with loss of power, and dropping MPGs. The more water in the intercooler the lower the MPGs. Additionally, when power and MPGs fall enough you can hear the constant swooshing of the turbos (by pass dumping) under mild acceleration – the water causes too much restriction in the CAC and is the sound you hear. It is usually easy to clear out the water, restore the power, and the swooshing sound goes away.
Other symptoms can be the Phoo Choo Phoo Choo. Engine running so rough you think you have a bad tire when accelerating to get back on the freeway after a stop. To a constant light engine missing just cruising along.
Once your MPGs drop by 5-6 MPG, you will begin to hear the swooshing under moderate acceleration. When your MPGs drop by 8-10 along with a major loss of power; you will think the truck is going to die. Just a minor Texas hill will force a downshift because the truck has no power.
To be clear, all of the symptoms I mentioned above can be quickly eliminated by clearing out the water. Now it may (usually) go into heavy surging and missing as you do that, but it has always cleared out in less than a mile.
As far as I am concerned it is the condensation that causes the vast majority of problems and issues in the EcoBoost F150. For me this type of engine does not work for Southeast Texas; particularly when passing through high dew point and temperature changes.
The above “bad events” I referred to above “only” occur on my truck when the dew point and ambient temperature are the same or within 5 degrees of each other. If those two temps are more that 10 degrees apart it will not happen at all, and the swooshing cannot be heard under any condition. The only time that statement is not true is when you have water left over from a previous event that has not been cleared out – like overnight and you forgot about it, then clear it out and all is good again.

The dew point and temps get close in many/most areas of the country though. They are within a few degrees of each other right now in Ohio. The difference is, here they will rapidly separate as the day moves on but in Houston I would imagine they could stay close all day long. This would also help explain why some people have "good trucks" while others have "bad trucks". If one guy left for work every day at 6 a.m and drove 45 minutes on a highway in the damp air, his engine could perform just as you described. His neighbor could leave at 9 a.m. daily and never build moisture in his because it was not as moist oustide. A third guy could leave at 6 a.m. also, but might have lots of 'stop and go' area and keep his moisture cleared out with heavy accelerations.
When you think of the testing Ford did on this engine, it was mostly torture testing. Even the 24 hour towing test in the damp FL air was done at WOT.
I'd like to see someone with a poor running EB take it out on a "closed course" and run the living snot out of it for 15 minutes. Then check the mpg's and overall performance again to see it it improved.
