OK, so when I first got my 2.4i, maybe in January, I had to break it in. All I had room for was about 120mph. So after a night of kicking the back end out and flying past people at 100mph+, my gas mileage began to suck. I need to know with the problem is because I can see my school from my window (Graduated) yet I dont think i can go a week on a tank. On a cold start i get about 6 or 7 mpg without barely touching the gas. My girlfriend lives about 30 minutes away (all highway), but I used to get 50 sometimes 60 mpg going 80 or 90 on the freeway. Now I cant even see 40's. Whats the problem? Tune up? Oil Change? Or the computer just wrong? To get around 20 mpg i have to switch to the ****ty manual automatic and practically stay in 5....can someone diagnose the problem?
