well im almost 100% sure i no the car up and down and thats the only thing i see i looked 4 a chip pullys intake nothin......

gills99stang · July 20th, 2007, 05:56 PM

Well, not sure right away what would cause the really bad gas mileage other than do you drive the crap out of it? Rev it high, etc.?

Get a chip/tune and that can make your gas mileage better probably...

Onemanzu · July 20th, 2007, 05:57 PM

the only thing that i can think is if it had 4.56's in the back

or a gas leak

gills99stang · July 20th, 2007, 05:57 PM

Do you smell gas underneath the car?

theyanks904 · July 20th, 2007, 05:58 PM

i have a 96 with tons of mods and the 04 is my Girlfriends car and mines dont even come close 2 sucking that bad ?

theyanks904 · July 20th, 2007, 06:01 PM

is there a way 2 check 2 see if there is diffrent gears in the rear end

JASonic · July 20th, 2007, 06:01 PM

Dude, somethings wrong. Something like that should throw a code I would think. My 04 gets about 22 mpg and has the same mileage. Somethings screwed. Did you buy it with a couple dead bodies in the trunk and not know it... that extra weight could cause some loss too.

Onemanzu · July 20th, 2007, 06:03 PM

i get 20 and i have a crappy falling apart single port...

im thinking that their most be something stupid like the tires are flat... or something so crazy that we wouldn't ever think of it

gills99stang · July 20th, 2007, 06:04 PM

In comparison, I get about 12 mpg in the city when I'm driving aggressively, but when you look at what's done to my motor, you wouldn't be surprised....

I get about 17 mpg on the highway.

Juggalo_X · July 20th, 2007, 06:05 PM
