Please Help Me (MPG?)
okay so i have a 99 max with no engine mods but a cai.....the problem is im getting 10-13 miles to the gallon....i have no CELs and i also had the obd2 scanner checked and nothing came up....i have 17 in cabo rims maybe thats why? well i bought a new KS but i wanted to know if its worth putting in? if theres no codes can that still be the problem.. any help on fixing this problem would be greatly appricated. by the way it is an auto

Yes. you should change you KS and see if there is a difference. You should check your air filter too. When I got my car - 98 GXE auto I got really bad gas mileage. Then I did some maintenance like new KS, good air filter, fuel filter etc and now way better!

yea fuel filter is my first suggestion if you are getting no KS codes.
but also you should just do a general maintenance-overhaul on your car; clean the TB, IACV, replace air filter etc.
if there was something seriously wrong like dead 02 sensors, or a knock sensor, your car would be throwing a code.
btw, you are actually getting your codes read right and not just assuming that because the CEL isnt on, there arent any codes?
go to autozone/advanced auto and have them scan your ECU for free

there are a plethora of writeups
both are pretty straight forward. just disconnect hoses/plugs and unscrew the bolts and you are all set.

You are probably calculating your MPG's wrong if you're getting such low numbers. Many things are probably in need of cleaning/replacing and you might want to consider doing a tune up to get your car to spec...
