Gas Milage Help *DESPERATE*
I was hoping to hear what other people are getting for current gas milage. I currently have quite a problem on my hands, my 01 with 3.55 and only 30x9.50's is getting 11 MPG. I drive like grandma, and most of the driving is going at least 45 to 60. I have a bored TB but it didn't affect gas milage at all. I checked both before and after installing and It didnt change one bit.
Recently I replaced the gas cap because there code was coming up and I was told that a stripped gas cap could possibly be the problem. I havent had any other codes and both the Cat and the Muffler were replaced back in Sept. It also recently got a fresh air filter. I am currently at 34 psi for the tires also.
I have to find a way to get better milage, or else I will have to sell my jeep . Anybody have any ideas?

Not sure how to help....I would maybe get a Scangauge on it and monitor TPS and gallons per hour. I think you have done all the normal things...tire pressure, gas cap, basic maint on the jeep. Is there any drag....brakes? Again not sure how to help?

I get between 15 and 17 but thats all city driving so far til I can get to the trails. I've got 31x10.5, not sure what gears are in it. Maybe the e-brake is dragging a bit? Did you try running injector cleaner through it? Something seems really wrong.

I dont think the Ebrake is dragging, I use it often and make sure that its completely down before I move the vehicle. I have been in a car where someone drove with the E brake still on and I know what it feels like, I havent experienced that at all.
I just put 10 oz of Lucas Injector cleaner through it. As in from the time from my last post to now I put 10 oz in.
I am a couple steps away from taking it a mechanic and let them look it over to see if they spot anything cause I cant see anything.
I know this time last year I was going 2 weeks without filling up, and I still make the same drives and I can barely get a week or less out of a fill up.

I know, and i love her, but seeing people get 15+ with bigger tires, gears and lifts is sad. I cant keep using it as a dd if im only getting 11 and I have yet to do any mods to really hurt the MPG
If there is a way to check the MAP id love to hear it, and me and my father will check the rear brakes tonight.
What other ideas do people have for a tune up? I though I covered most of them. I can try fuel filter, plugs, and IDK wat else.
