13 mpg. WTF
 

I have been through 2 tanks of gas and I am averaging 13 mpg.

On this last tank I didnt do much racing and for the most part I drove normal.

This sux,

Have you noticed any knocking, stuttering, shaking with the car... 13mpg doesn't sound right, when you baby the car you should get much better than that.. now... WOT all the time will get you those numbers... Maybe something's wrong with the car and it hasn't tripped the CEL circuit..

Every once in a while the idle is a lil' rough. Other than that the car runs fine.

Pull some of the plugs out and see if there is any discoloration, other than normal, on them. Maybe it's running too rich , or lean. Listen for vaccuum leaks under the hood. You may want to bring it down to AutoZone and have the Code Scan it real quick, the computer may be giving off a code or two w/o tripping the CEL light.

i`ve heard of this before it turned out to be injectors staying open contiuously so it`s like your running wot all the time even when your not check your exhaust and your oxegen sensors
