Anybody know what could help?

Jeeps do not get good gas mileage. You just have to realize that going in and be willing to live with it.
The best way to get the most gas mileage out of your Jeep is to drive it slowly. The aerodynamics are like those of a brick. Speed increases wind drag, and costs you on gas mileage. I have read that as much as 80% of the engine's power is used to overcome wind drag on a vehicle cruising at highway speeds.

It's funny how some things stay with you. It was around 1979 or so, we were driving across Iowa on I-80. We were cruising at about 80 mph, heading into the setting sun. A Wrangler blew by us, a guy and a girl in it, it had one of those half-tops, the girl had her leg out on the running board, and it had California plates. The girl's hair was blowing in the wind, and the guy had an air of both confidence and unconventionality at the same time. That image projected a sense of freedom, and of fun, Then and there I knew I would have a Wrangler someday.
I will order a Sport, 6-cyl, 5-speed, and everything else. As in much of life, there are some inexplicable rules - why can't I have a Traction-Lock rear axle with a leather wrapped steering wheel? Only Jeep knows.
Seriously, if increases like this were available at such a minimal engineering cost (less than a buck at manufacturing level), DC would already be doing it. Just look at the hoops they already jump through to meet C.A.F.E. requirements.
As for cutting out the roll cage. There's no need to, the stock one just bolts in. There are several after market cages that you can get. Everything from bolt ins that reinforce the front of the cage to complete replacement cages.

Are you serious about that or are you being sarcastic. Because 15 to 20% increase would be around 20 to 22 miles city, and 25 to 27 highway. Well I am just guestimating those numbers, but that would be sweet.
I do not have any experience with a bored out throttle body, but doubt there would be any significant gains in mileage. With modern engines, many times the ECU will adjust to intake changes, reducing or even negating any perceived gains within a short time span after the changes are introduced.
Anyone that is concerned with MPG, the Wrangler may not be the vehicle for you. I get a consistant 15.5 today, but was only getting about 17 in stock form. I have a relatively heavy foot, but never got more than high teens, even with sedated driving. The only time this is really a pain is on road trips. Stopping every 250-275 miles can be a drag but is a good excuse to stretch your legs.

To reiterate, IMHO, throttle body spacers, bored out throttle bodies, spiral grooved throttle bodies etc., etc., are pure snake oil on a fuel injected Wrangler. They can however, have a place on carburetted engines at WOT, i.e. at the dragstrip and racetrack.
Again, if such amazing increases could be obtained with such inexpensive engineering, DC would already be doing it.

Ironically, it's often the small 'mom & pop' dealer that provides the after sales experience we all hope for. Despite the surveys, the advertising, the staff training, and of course the money spent on the expensive sign out front, a lot of the 'all singing, all dancing' Five Star Dealers fall way short in that respect.

I hope I don't have to go through the Jeep Parts department. Thanks
(Sometimes I kill me.)

BTW: How's the "no smoking" thing going? Still smoke free I hope.
This past Wednesday night marked twelve weeks on the smokin' thang. Still on the wagon, but barely holdin' on at times.
When we wheelin' again????? This Saturday?

Check your paperwork, or contact the dealer, to see if this is a recurring problem or a variety of different problems. The dealer won't have just turned off the light, they will have fixed the cause of it as well.
Either way, it should provide an indication of what you need to do to prevent it happening again.
Guess you are close to runing out of warranty, Bama? I would want it fixed right before the warranty expires, if I were you.
Tom

I know I'll be glad when things get back to normal so I can join you guys again!
BTW: Now the starter has gone out on the Jeep.

.......If any of these monitors detect a problem affecting
vehicle emissions, the Malfunction Indicator Lamp
(MIL) will be illuminated. These monitors generate
Diagnostic Trouble Codes that can be displayed with
the MIL or a scan tool.
The following is a list of the system monitors:
² Misfire Monitor
² Fuel System Monitor
² Oxygen Sensor Monitor
² Oxygen Sensor Heater Monitor
² Catalyst Monitor
² Leak Detection Pump Monitor (if equipped)
All these system monitors require two consecutive TRIPS with the malfunction present to set a fault.
Refer to the appropriate Powertrain Diagnostics
Procedures manual for diagnostic procedures.......
TRIP DEFINITION
The term “Trip” has different meanings depending
on what the circumstances are. If the MIL (Malfunction
Indicator Lamp) is OFF, a Trip is defined as
when the Oxygen Sensor Monitor and the Catalyst
Monitor have been completed in the same drive cycle.
When any Emission DTC is set, the MIL on the
dash is turned ON. When the MIL is ON, it takes 3
good trips to turn the MIL OFF. In this case, it
depends on what type of DTC is set to know what a
“Trip” is.
For the Fuel Monitor or Mis-Fire Monitor (continuous
monitor), the vehicle must be operated in the
“Similar Condition Window” for a specified amount of
time to be considered a Good Trip.
If a Non-Contiuous OBDII Monitor fails twice in a
row and turns ON the MIL, re-running that monitor
which previously failed, on the next start-up and
passing the monitor, is considered to be a Good Trip.
These will include the following:
² Oxygen Sensor
² Catalyst Monitor
² Purge Flow Monitor
² Leak Detection Pump Monitor (if equipped)
² EGR Monitor (if equipped)
² Oxygen Sensor Heater Monitor
If any other Emission DTC is set (not an OBDII
Monitor), a Good Trip is considered to be when the
Oxygen Sensor Monitor and Catalyst Monitor have
been completed; or 2 Minutes of engine run time if
the Oxygen Sensor Monitor or Catalyst Monitor have
been stopped from running.
It can take up to 2 Failures in a row to turn on the
MIL. After the MIL is ON, it takes 3 Good Trips to
turn the MIL OFF. After the MIL is OFF, the PCM
will self-erase the DTC after 40 Warm-up cycles. A
Warm-up cycle is counted when the ECT (Engine
Coolant Temperature Sensor) has crossed 160°F and
has risen by at least 40°F since the engine has been started..........
To summarize, it takes two consecutive starts with something 'gone bad' to set the light, and three consecutive starts after it's been corrected to turn the light off, then forty consecutive 'good' starts to erase the fault code from the computer's memory.
Of course, if one has the appropriate scan tool the resets can be done at will.
Oh, and turning the key to the 'ON' (not START) position three consecutive times within five seconds will display any codes on the odometer. This works for some, but not all, model years.

Yeeeeeeeeeeeeehawwwwwwwwwww!!!!!!!!!!!!!!!!!!!!
I did it, I did it, I did it!!!!
That was the fourth attempt, and that was yesterday. I ran it again today, but had a lot harder time.
I will post some pics as soon as I get them hosted somewhere "acceptable." I think I have some room on my free webspace from Earthlink.
I already have pics in "you know where," but I ain't allowed to post links. Oh, by the way, Gill's mom died today.

These pics were actually from today's run in Buttpucker, and I had a lot more trouble getting through there today than I did yesterday.
You can see the problem. The wall of the gully on the drivers side is just too straight up and down for any side bite of the tires. What I had to do was get the left rear tire over more to the left (to the right from the perspective of the photographer). I had to do that to get the rear differential from hanging on the hump in the floor of the gully.
Thanks, Steve.
You know, if you and your buds would just take a few buckets of gravel in every time you go to the Gulch, you'd have those ruts filled in no time ;-)

It was a BLAST! Wish you guys could come ride with me sometime like Paul did.

Looked a lot drier there than when I was there. I leave for Huntsville tomorrow and fly back home Thursday night or I'd join ya again.

Paul - did you ever make it over to Hungry Valley? I haven't been there in a while - in fact, my poor Noble Black Steed is just sitting there, looking reproachfully at me - we took the Taco to NorCal this past weekend, and it looks like we'll take it to Vegas this weekend. Maybe I'll talk my other half into driving it to work one day this week - I don't think it is a good idea to let a vehicle sit without starting it for 3 weeks, is it?
So yes, send him to work in it, but don't just start it for five minutes because it's sat for three weeks.
Last weekend we put on the Warn front diff skid plate and the Trilby gas tank skid. Got the CB installed and ready.
I'm going with 2 other Jeeps, 1 is an older CJ. The other is a TJ set up similar to mine.
It should be a blast. I can't wait. We will drive over Tuesday the 6th and return the 10th.We are going to camp the first two nights and get a motel for the last two nights.
If anyone else from this board is going let me know and maybe we can get together for a beverage.

Would that be some kind of hat?
