My car is only getting 14-16 miles to the gallon. I have replaced all O2 sensors, put a cai on, gutted the main cat and cut out the resinator, replaced all the spark plugs and wires, cleaned the intake manifold and added fuel additive to the gas. Before i did all this my car wasnt even reaching 12 miles to the gallon. Im barely getting 220 miles to a tank driving as nice as possible. I can't think of anything else. Dose anyone have any ideas in which would help me??:shrug:
