Edit: i have deduced that the backspacing is 5.5 were as ours are 5.25? But still unclear on the center hole size

On a side note, My Jeep lately has had power and everything, and then when I go to turn it over all the power cuts out completely and then it is all dead. I tried taking the NSS out to clean it, but it would NOT BUDGE off of the shifting shaft. I hooked the battery back up and bolted the NSS back down and it started right up... Any ideas?

Assuming you're running stock wheels/tires/gears/and your speedometer is fine, you should consider the following:

- Do a tuneup including oil and fluid changes, spark plugs, air filter, and all that. Gummed/soured plugs, fluids outside of spec and clogged filters can cause poor efficiency.
- Commonly the exhaust manifold cat develop a crack, most often on the downpipe weld near the collector way down by the flange that bolts up to the cat. I bought my 1999 and within a week or so this busted open. Drank a ton of gas, made a slight gurgling/hissing sound (especially under acceleration) and smelled pretty bad. Originally I thought it was fuel but it's the same smell as when a car warms up in the winter
- Over time the pre-catalytic converter O2 sensor can get dirtied up and lose sensitivity and cause an unnecessarily rich mixture... similar to an exhaust manifold leak
- Are you running with the defogger on all the time? My last car had no AC, so I got used to having air blowing on the windshield constantly. Imagine my surprise when I found in the manual that, even though the **** isn't marked (and there's no light... grrrr) the Defog vent control actually runs the AC system when its above freezing outside. For a month I was running my air conditioner without even realizing it

Once you rule the above out the problem may be more in depth.

Edit: I have poor record keeping (forget to reset trip odometer and write down fuel consumption) but I got 21.something MPG over Christmas break carrying 4 people up to the family's place for dinner.

*Edit: I went out and bought some Iso Heet. It's a fuel antifreeze, water remover and injector cleaner. Also poured in some octane booster for shˇts and giggles. Got some gas too so all the additives could mix in real well and drove around about 10 miles. I'll have to let the Jeep cool down and sit for a bit and start it up later to see if the problem reoccurs. I'll let you know what happens.
