it was a lease and time to get out of it...
just like we leased the explorer sport (that the wife (and I) are very happy with up to this point) will have to go back at some point...
BUT, there were many reports on the forums about the Audi/VW/Skoda 2.0 DI turboed gas engines having build up issues around the 40 to 50k mark... and since the ecoboost is basically a turbo-ed DI gas engine, thought it was relevant but didn't realize I had posted it in the 2015 section... last time I was in here the 2015 section was not the first forum

Expanding on my last post, besides a lead foot, excessive heat and oil starvation are likely the main reasons for turbo failure...look it up. Turbocharging has been around long enough for the various manufacturers to solve these issues. GM has direct injection on several cars. Does anyone know if they are having the same problem with carbon buildup on the back of the valves?

Certainly robs power as the mileage goes up...is it going to cause a catastrophic engine failure, well the jury is still out on that one, with the amount of di engines out there with all this carbon, I would say no. I don't know anything about turbos and di so I can't comment on that, but for sure almost every mass produced di gas engine out today has these carbon/coking issues.

If they could come up with a solid and reliable water/meth injection system I think that could probably solve the issue. It would add cost due to extra parts and you would have to buy and fill the water/meth tank. But an added benefit would be more power, reduced intake and exhaust temps and etc. I would imagine it would help greatly to keep temps down when towing heavier loads.

I buy vehicles with a 200k mile target (even if I sell after 100k they will have resale value) and frankly I don't feel good about anything with DI at this time.

I have a 2011 3.5 with 92kmiles. I had the induction done at 65k miles when I first bought the truck used.
If I caused damage, would I have noticed it by now?
Is the can a good way to avoid this issue? Wonder if its too late to put one on now.
Edit.
I'm just looking over my bills and realize the ford dealership did an injector service on my truck when they did an oil change. Was about 1.5 years ago and can't remember what it included. Wasn't an issue back at that point.
I'm pretty sure many people have had the induction service done by now and doubt there are many failures to date.

I have a 2011 F150 with 3.5 EB. Have had misfire issues from the start and had all of Ford's TSBs done on it. In fact I was part of the class action suit against Ford on the EB misfire issue which was dismissed by the courts. I now have 70K miles on it and when I accelerate HARD up a grade (such as an entrance ramp to a highway) the engine misfires terribly as it reaches high RPMs as it shifts through the gears. Especially noticeable when engine is cold. Reminds of the old days with carburetor motors when you had to occasionally blow them out with hard acceleration to burn out the carbon. I want to order a new 2015 but am not sure as to which engine to go with. I want good fuel economy and am considering the new 2.7 EB in hopes that this second generation EB may be a better design. ???

Hmmm. I am totally not a mechanic but...if all the Tsb's have been done, I'm sure they changed plugs somewhere along the way.
My eb was misfiring on hard acceleration enough to bring on a steady code. I took it to a jiffy lube and got them to read the code. Misfire on cylinder six (why is it always 1 or 6?). I changed the plugs cause it was easy and cheap $60. Misfire still there so I changed the coil pack. No misfire now.
I could have moved around coil packs before I bought one but I figured changing plugs is a good thing and I don't have a code reader, which meant a triip to a parts store so they could re-read the code and see if the misfire moved. Just easier to change the coil pack

I'm guessing it's just plugs or a coil pack because that was my exact symptom and fix. Wouldn't it be great for you if it turns out to be such an easy fix!!

An interesting note to add to this thread - any of you guys check out the new Ford GT debuted today? It has the 3.5 EB engine now with 2 injectors per cylinder. One direct and one in the intake port. I'm not sure (at all) if this is because it needs more fuel for increased power, if this is common to '2nd gen' EB engines, a combination of both or what but it seemed pretty relevant to this topic.
