The p0113 is intake air temp circuit high.
Check the intake tube between the air cleaner and the throttle body to make sure everything is tight. An air leak there will cause the lean codes you are getting. The IAT is also located in that tube, if it isn't seated or not there then you may have found your issue. Check the electrical connector to make sure it is clean and making good contact. I believe the IAT is located on the bottom of the intake tube. Also check the grommet where the wires go into the air cleaner box (the part that comes off when you change the air filter) to be sure it is seated.
Are you getting any misfire codes?

I checked the electrical connector and it does look pretty dirty but is connected properly, the grommet looks snug and clean, and the air filter is new...I rescanned just to make sure I got the codes right... and the code P0701 is now pending and codes read are P0113 and P0704 not sure if it matters wether the code is read or pending...

Let The Misfire codes reign in...
Changed mass airflow sensor and IAT Sensor that got rid of the P0113 but not P0171 or P0174...Now unlike before it also reads a couple of misfire codes...One stating its misfiring under 1000 revs P0316 and one misfire on cylinder 3 P0303

I was changing the throttle body gaskets when i Noticed there was oil in the throttle body...does it belong there? i was also wondering if there really is a vacuum leak or its just the pletnum getting excess air from the throttle body causing it to whistle?

So after changing the gasket on the throttle body, i re scanned after 25 starts and only code that shows now is p0174...so im guessing it was multiple problems leading to the same code?

That did it! After 2 weeks of bi polar codes read... Trucks back to normal! no sputter,no hesitation, and best of all the service engine light just went away after fixing the exhaust leak, Thanks!
