Hello everyone,
I have a 2014 Ecoboost FX4 Supercrew, with 3.55 gears. The past week or so I have noticed that the RPMs at highway speed are higher up than they usually are. Normally I can run 75 at about 1800 RPMs, but here lately its closer to 2000 RPMs. Any thoughts on what would be causing this? It has been cold here the past couple of weeks (high teens to mid thirties depending on the day). Interested to here anyone's thoughts.

Thanks
J

Finally!!!!
I figured out what was causing this issue, and now the truck is running like it was the day I got it. Such a relief.
