A faulty fuel pump would cause your Navigator to hesitate when you accelerate. Bad gasoline could also be At Fault.
Not using premium fuel caused that in my 2004 Navigator.
no it does not
Because you bought the 1.6. Get a 2.0D and the problem will go away.
Sounds like it could be a dirty fuel filter, try taking it off and cleaning it.
The MAF sensor may be in need of cleaning.
Change the fuel filter and have the cat convertor checked out
There must be a restriction within the intake. Snow? ice? Mark
Timing chain - sloppy?
You need to use premium fuel, the fuel u are using can cause predetonation, and cause knock. Which will ruin your engine

Your power steering can use 20 horsepower, under normal operational load (without any problems in the system). This is a considerable load on low horsepower vehicles and can cause hesitation.
