  1. Engine & Drivetrain
    2011 Acadia Denali I drive the same miles to and from work. Same route every day but yet when I check how my fuel economy on my instrument cluster, one day it will show 10.6 MPG then another it will show 16.7. Any idea why it is so sporadic? Again I have changed nothing on the car in between...
  2. Engine & Drivetrain
    I have an Acadia 2009, after changing spark plugs and two fuel injectors, the fuel average goes down to 11 MPG. How should I increase it?
  3. Engine & Drivetrain
    Whenever I put gas into my Acadia it idols really rough like it wants to cut off... Funny thing is if I turn the car off and pump the gas in it then it takes forever for it to crank back up. It had also started sounded like a diesel vehicle for some reason. Any ideas? Thanks ahead of time.
