It's now somebody else's problem.
For the past 2 years, multiple dealerships and factory reps changed out parts/computers/filters and it still had a rough idle at stop lights with the a-c on as it always is in S. Fla.
Found a 2011 Latitude,2.4 L/ Auto 4X2, Black Pearl, Leather Trimmed, Nav/Media Center, 17 Inch Tires, Alloy Rims.
Tires feel different, handling feels crisper as if they tweaked the suspension/steering...and the extra 20 HP is easily felt in the seat of the pants.
Road feel is different, definitely smoother and it could be the tire combination.
Highway Acceleration seems improved, could be a possible axle difference if there is one.
Overall upgraded experience from the basic '09 2.0 Sport we had.
Leather steering wheel, seating surfaces and nav/media center add just enough bling...but not too much.
