so I bought a Jeep that was only half running when I got it and I've fixed most of the problems but I have some general questions. it's a 93 grand Cherokee Laredo 4x4. I don't have a console yet and no matter were I put the lever for the 4 wheel I cant get it to engage into full time and I wonder which would give me better mileage 2 wheel or full time. I also am wondering about the fact that I am getting like 10 maybe 12 mpg and I'm driving like an old lady and I've run injector cleaners, sea foam carbon cleaners, and Lucas stop slip transmission and I'm told I should be getting 18-22mpg. so I have no clue what it could be. so if anyone knows a way to improve it please let me know. it will be much appreciated. i would also like to know what a decent size and type of tires would be good if i'm just driving it as a car and for light camping other words i want it to ride good and not get stuck in GA red clay
Believe your case positions are 2wd, full time, part time, n, 4lo. Is it an 8 or a 6 cylinder? Duratrack, bfg at, both great highway medium off-road, but can be a problem in sticky mud. Bfg long trail is great highway, light off road, poo in mud.

if you havent changed the plugs and you plan on doing so, use the plugs that are on you emiisions sticker under the hood. Should be a champion copper plug. Be sure it has an OEM O2 sensor, not a Bosch.
It's a 4.0 so no plenum. Don't put any Lucas or other junk in your tranny. It doesn't meet the requirements that your trans fluid does and should be used as a last ditch effort if you need a rebuild. Other than that you are just diluting your transmission fluid. Make sure your battery cables are clean and change your plugs, wires, cap and rotor, 02 sensors, oil, air filter, and make sure your catalytic converter is in good shape. If you just got it, I would change all of the fluids in it to the last drop and replace with brand new. There is a good chance that your t case shifter linkage needs to be adjusted which isn't hard to do just do a search. Also 2wd doesn't give you any better mileage, the front still turns no matter what.
Like many people have already stated... Do a complete tune up. new spark plugs, new wires, new cap and rotor, new ignition coil and ignition wire. Change your air filter, properly inflate all your tires. Clean your throttle body, clean your IAC. Hell even change the oil in your transfer case and front/rear diffs. While you're at it, replace your O2s as well
