ChrisC2011

Hi guys, I am new as can be to this great site! I have a 2011 5.0 like clock work, every time there is colder weather (45 degrees or colder) My truck will just crank until I press the accelerator once and then there will be ignition. It idles rough and the mileage goes down during this colder weather as well. I am getting a couple codes "Too Lean-Too Rich Bank 1 and Bank 2" Any thoughts or answers to this issue? I have cleaned the MAS and thinking it may be an engine coolant sensor affecting the IAC.
Thanks in advance!
