High mileage eco boost bogged down

First off Merry Christmas everyone.

It's been awhile since I've posted, but I wanted to ask around and see if i can get some direction as to where to start diagnosing my truck.
Its a 2012 f150 ecoboost with 210000 miles. Over the past couple days i have noticed its driving like im pulling a trailer with it, except im not. The throttle response is reduced and it slows down more than it should going uphill. It starts and runs perfectly normal other than that. Any ideas where to start will be appreciated.
Thanks.

Asking about "the regular stuff" is a good place as any to start. Spark plug & coil replacement done? How about the air filter, how's its condition? I know it's probably colder weather but any pinging?

bigredman...
In addition to spark plugs and air filter...
.
  • Check and clean the throttle body if warranted.
  • Clean the MAP sensors. The EcoBoost has 3 MAP sensors ...
