I have a 2000 civic ex with 61,xxx miles on it and I havent been getting the gas mileage lately. Someone mentioned to me to changed my spark plugs, I did that and I didnt really see a difference??..What can I do...I havent been driving my car harder than normal, so I dont know what to do. thanks

 

well if the plug wires haven't been changed in awhile I would replace those along w/ maybe a new rotor cap and button, as they aren't that much. also when's he last time you changed the oil? If it's been sometie I would recommend that as well so it's not all dirty and sludgy in the internals..
that should help out unless you have clogged injectors or something else that not letting your car give you the better gas mileage you expect....Good luck
