The right gears generally aren't available if you have a 3.07.

 

Seems like I'm getting worse gas mileage since doing my tuneup and TP sensor but I've also installed 31's as well. With 3:55's and 31's I'm wondering how far off my speedo is?

 

I have no idea on mine it never goes that far on the hiway or in high range, I always figured it is what it is. The price of having fun and that is what it's all about

 

Just filled up again today. I can't remember where I saw it but someone said they shift at 1800rpms so I gave it a try for this last tank. Well other then a handful of times romping on it I got 14.6mog vs the last tank I got 12.4mpg.

3" lift 31's, 5spd and 3.07's for now. Plan on swapping in a 3.55 d30 and 8.25 combo some day.

 

It seems like no matter what I do my mpg only gets worse. Fixed my massive vacxum leak and swapped in 4.10s and lost an mpg.

 

I filled up today and the light had been on for about 20 miles ago in total was about 280/300 to a about completely empty.

 

I feel ya bud

 

I just bought my 98 and before i could give it a tune up i filled it and get about 260 at 14.7 miles potter gallon and that's a 50/50 between highway and in town

 

I give up. Im just gonna get crap mpg. Lol.

I dont think 16-17 mpg is too much to ask for.

 

I'd be happy with 15-16. Right now I'm on track for 11-12. It seems like the gauge is constantly moving while I'm driving lol

 

Im gettin 14. I get that its a jeep and its no gas supper but I'd still like to get the most I can with what I got

 

Yea I'd like to get 14. I'm almost to half a tank and I've only put 137 on this tank. I'm trying to think of what I can do to get a little bit better mileage. Like cold air, programmer, exhaust, O2 sensors.

I just did plugs, wires, cap and rotor, cam pulse ring and throttle position sensor. I know with 31's and a roof rack it's gonna be a little hard. Plus with an automatic. Though it does have 3:55 gears.

 

I was doing 16-17 with 31s

Programmers dont do much. I think im gonna replace my I2 sensor again. Maybe that's contributing

 

Dang I wish I could get that. What gears did you have and did you have a roof rack? Also are you auto or 5spd
