Actually I answered the question you asked. But try this also... When was the last time you did a tune up? Have you cleaned your fuel injectors and intakes? Have you cleaned the mass airflow? Have you had a data scan to see if anything is out of parameters? Have you even changed the air filter? And lastly how cold has it been where you are at?

Okay last tune up was 1000k ago. Plugs, wires, air filter, mass air cleaned, oil change, cleaned intake and tested injectors and yes I have hooked it up to a scanner and nothing has popped up.... And lately -5 Celsius

How's the performance of it? if the cats were plugged there would be a severe drop in power also.

You see colder temps and winter blend gas equals lower fuel mileage. Do you let your truck warm up before driving?

This is 1 million miles
Did you mean 1 million miles??
1000 x 1k = 1,000,000 - 1 million miles
