<HR style="COLOR: #5d7790" SIZE=1> it seem like over the last two months my fuel mileage has been going down what could make this happen. i have also replaced all the fuel filter so i no that is not the problem. also what kind of fuel mileage are you guy getting around town? oh it is a 1999 2500, 4x4, 3.50's, auto, and it has 285/75/16 and it is all stock for the moment.

ive got a 01' and im getting around 16-18 around town, just depends on how many hot chicks i see on a tank:grd:

copy that!

lol:ro) :ro)

Air filter?? Is your truck a Cal. truck? If so your cat could be stopped up.
