Ive...changed plugs ( ngk cooper), knock sensor, o2 sensors, fuel filter, cleaned throttle body. I'm gettin 23 on the highway at 75mph and 17 in the city. I had a 96 automajic that got 28 on the highway and 22 in the city , it also had 120000 plus miles. My max ia a 95 se 5 speed with 126000 very well cared for. Any help?? Thanks

 

I get 14-16 MPG in Chicago and I don't think it's getting any better than this for me Too much slow driving and traffic is killing my gas mileage. Raise your tire pressure to 32-35 all around or something
