Hey! I'm new here and I'm a girl with general auto knowledge but im by no means a mechanic so speak English to me!
I have a 2007 Tahoe LTZ 4wd. I was getting about 16.5 mpg (combined), had to put on a new throttle body (was throwing code/chk engine light), after the new throttle body my mpg has gone down to 12.9.
Does anybody know why? Or what needs to be done to fix it? Gas is cheaper but still not free so I need to get my mileage back up.
Thanks!
