hello everybody! i recently bought a 1990 honda civic hatchback with the hopes that it would get great mpg but so far the best i have been able to get is around 16 mpg. i had to replace the oxygen censor and air filter just to get 16 mpg. before i did that i was only getting 12 mpg. does anyone have any ideas as to what the problem(s) might be???
