Before I go waltzing in to the dealer with this, thought I would ask for some of the experience here. I have a 2012 F250 FX4 and for the first 2543 miles it was awesome. I could easily get 18 mpg average (lots of 19 and change if I was on the freeway and unloaded - that's calculated and on the computer) with power out the wazoo. Then it's like someone flipped a switch. All at the same time I got:
Mileage of 16 - 17 mpg IF I was very nice to it
NO real get up and go (passing a car and asking the truck to go from 50 to 80 used to be a non-event. Snap your head back. Now I put in reservations.
A noticeable ticking/clicking when the truck idles after it warms up
A lot of different noises after the truck is warm and I shut down.
I should also note that the boost says I am still getting 10 to 20 depending on how hard I push the pedal but my butt says it's not really there.
Anyone have a similar experience and know what was done to correct it? Not new to mechanical stuff but am new to diesel so I don't want to show up TOTALLY ignorant when I take it in.
Thanks ahead of time.
