2005 Suburban z71 Flex Fuel
I have a 2005 Suburban Z71 5.3l with Flex Fuel.
Used to get 19-21 mpg. After fuel pump went out, Changed fuel pump and flex fuel sensor. Now it's getting about 10-11.5
I now also am getting code P0449
Could tCoulee the reason my milage is waaaay down? It's not making sense to me.
