Let start off with my car, its a 95 dx hatchback with 78000+ mileage and so far i havent done any major tune up or whatsoever to the car. It use to run like 34 freeway and about 27 city, but now after i installed my aem cai + 4-1 DC header, i run like 22 freeway and like 19-20 city, can someone tell me why this is happening? Was it because of the header + cai? or could it be bad o2 sensor or something.. please help a newbie out, please dont flame at me if ur not intend to help, thanks for all the help

maybe that would help , and it's not a bad idea to test the o2 sensor too

You gotta give up something to gain something rite? Now the next question is to decide was it worth it? If its a DX motor, then why not just enjoy the nice mileage until you save up enough for a swap if you ever plan to do one, cause it will be waaay worse than that!
