bad gas milage, gotta love that three O deuce!
 

the stang in the sig. makes bad gas milage. i cant expect much in nyc, but it only gets around 11-13mpg. i feel like it used to and should get at least 15 maybe 16. i have fairly new plugs, new wires, new fuel filter, cleaned the stock TB, new tires, tire pressure 30-35 psi. anything else i can do?

also, when i replaced my stock exhaust w/ an o/r xpipe and magnaflow cat back, i noticed i can smell a good amount gas fumes, but i figure this was cuz of no cats, am i right or can my car be running rich?

i also forgot to mention new cap and rotor, cleaned the K&N, and new O2 sensors. thanks.
