I'm considering buying a Flex EcoBoost and while reading up on this engine I found something that concerns me. It seems that DI engines have a tendency for carbon to build up in the intake and on the intake valve stems which can lead to maintenance issues in very few miles. I like the idea of having the extra power in a vehicle this big but if this is a common problem with DI engines I may just opt for the NA version. Any info on this available? The forum I found this thread on said the VW DI engines had the same issues. This car will be replacing my daily driver which has given me 182k miles of trouble free service and I want to make an informed decision.
Thanks,
Rodney
