I do city driving, max is usually 40mph. I live on a road that has everything I need within short distances.
According to the DIC, I was getting 18.5 mpg.
Then I did the lim, 180tstat, new plugs and wires, and now the DIC says im getting 15.6.
What couldve possibly changed so much lol?
Would a vac leak make me get bad city mpg as well?
