I've got a 94 wrangler it's got a 2 inch shackle 2 inch body and 4 inch suspension lift. I'm rockin 35s and I've got 4.10 gears and a locker. I get bad like real bad mileage which is understandable. But I feel it should be better then 12-13. I've got the 4.0 HO. I changed the plugs, wires, cap, rotor, oil/oil filter, fuel filter, and cleaned air filter too. I know my tps censor is bad but I haven't got a new one yet.
I'm new to jeeps but I figured doing all that and having the new gears would improve it somewhat. But it didn't. Would replacing my sensor improve it? Or is this just something I've gotta deal with. Is there anything else I can do to improve it?
What is your driving style?
That is the biggest variable in milage.
Heavier foot on take-off. Gassing until last second then braking for stops. Pushing the rig past the most efficient cruise speed.
You can't hyper mile a shoebox on wheels but you can stretch the possible. I notice that highway at 50-55 I can get ~18 mpg but when the speed limit is 65 and I try to stay with traffic (65-70) I get around 12 mpg.
I would love to get 12mpg. I am currently at about 10. But I am missing a bolt in the exhaust manifold and that has alot to do with it. If your manifold cracked? All things considered though you are doing pretty good gas milage wise.

[QUOTE=Overhead;17658665]this is also my second set of RC springs this year. I'd rather spend the money again and get something that will last.[/QUOTE]
What engine and transmission?
Did you change the speedometer gear?
Did you upgrade your steering and brakes for the 35's?
Do you have GPS on your phone, so you can see what your real MPH's are?
Your actual MPG is most likely higher since your speedo is way off since you have 35's.
You are driving a BRICK and there's very little you can do to change that, but running a 4.56 or 4.88 gear will help your gas mileage and keep your engine in it's powerband. I could get 18 or 19 mpg's with my old YJ on 32's with the 4.10 gears.
I don't romp the sh** out of it but I do like the sound and speed of my engine haha. Not sure about the manifold but I'll give a check. I've got the 4.0 straight six HO with a five speed tranny. And yeah the guy I bought it from updated the steering and breaks for 35s. He had 36 inch swampers before he put the 35s on. But could a bad tps sensor have anything to do with mpg?
