Techstream help ?

Hi guys my 2014 prado 2.7l 4cyl auto is not doing well , loss of power on the low end. especially uphill. No lights or codes. Idk if its a clogged exhaust or clogged injectors or bad Maf of AF sensor ?
I hav some reading from tech stream hopefully that'll shed some light on the issue.

 

Anyone ? I Really need help because im in a remote location and my truck wont make it up the hills to the city. So i need to fix it here my self if possible
