I used to get over 300 or so miles on a full tank, and now im gettin about 240 or so...can anyone help? spark plugs maybe? hmmmmmmmmm, THANKS

 

Colder weather won't help. How many miles do you have on your car? Might be time for a full tune up. Change your oil. More info helps

 

do you have any mods to the ecu?

Same thing was happening to me too but after I changed my oil and did the usual maintenance, I'm getting good gas mileage again.

Its got 68,680K miles. Everything is stock besides an ebay intake (changing out soon). The 2 hoses that connect to the intake are not connected to the intake due to making a custom-ish intake, but it will be connected again once i get a new intake on it, could that be some of the cause?

 

Did you change the air and gas filter yet?

 

yeah sounds like you should change the fuel filter, that will cut down your mpg.
