i have a 98 SE 5spd and i recently changed out 2 of my o2 sensors, knock sensor, cleaned K&N air filter, new fuel filter and also cleaned out the throttle body but for some reason my gas mileage has not improved at all...it seems like im gettin same as b4.....19 mpg with 90% highway driving.....i baby my car...rarely ever go WOT.....

i was just wondering what else could be the problem? i used a scan tool and i dint pick up any codes? is my car just S H ITTY when it comes to gas mileage?

what other things could lead to low gas mileage?
