what should i do to improve my gas milege in my car? i just got a injen cold air intake and hopefully that would help a lil but is there any kind of chip module or unexpensive parts?

get rid of roof racks, bug deflectors/wind, proper air tire pressure, less weight on the car. Nothing much else to do. Just be as light and as aerodynamic. That's what i did to my rx. Removed the racks, and made it lighter by taking out the spare tire. I have a tire monitoring system anyway.

also going easy on the accelerator in the city and braking early. make sure you get quality gas because buying the cheap stuff will actually drop performance and mpg so it actually saves to pay for the better stuff.

Clean the fuel valves/injectors, over-inflate the tires a couple lbs (it'll ride stiffer though) and as numerous people mentioned, get rid of unneeded, extra weight.
