Ungrateful little so and so!

The 93 Wrangler has survived "stage 1" of going from strictly stock, moving towards getting him ready for retirement as a daily driver to a toy and week-ender.
After getting upgraded seats, air intake, catback, engine rebuilt, overhauled tranny and trans, swapped out the 225's GY wranglers with 31"x10.5" TA/KO's, and one really cool tribal lizard decal on the windsheild (most important upgrade there!), the ungrateful little so and so decided it was going to throw a fit and decided it was going to go wacky with the gauges.
I knew I was going to maybe get some better gas mileage with the upgraded air intake and exhaust system, but 180 miles on a 16th of a tank of gas is a little suspicious at best, the oil pressure gauge is also for no reason just pegging out at 80+, then drops back to a more likely 40 to 50 depending on RPMs.
Looks like the voltage and temp gauges are working fine, just oil pressure and fuel gauges throwing fits.
Any easy ideas as to check whether or not it is the gauges, sending units, or an electrical fault?
Any thoughts are welcome!

I mechanic as a profession. The way I check to see if the gauges are working, is take out the sending unit and simply hook in an aftermarket gauge. I am not sayng install after market gauges just hook them up temporaly to get an acurrate reading. I just bought my yj and it was doing that with the oil gauge I changed the oil and it is consistantly 55-60 pounds now. Good Luck -Aaron-

Today, the blower fan for the vent system decided it was too lazy to work, but the oil gauge started reading true again (for a while at any rate) I have checked the fuses, relays, grounds, and wiring in general and see nothing out of place, frayed, burned, or disconnected.
So at this point, I am going to cede this battle and drop him off at the dealership and hope for the best as far as my wallet is concerned.
Something freaky is going on with it, perhaps it is rebelling because it has been parked too close for too long to my neighbors Suzuki Samauri.......

Hey, right now with the trouble I am having with this POS YJ, I'd love to have either of my two Sami's back. Never had trouble with either of them. Traded one in on a Toyota 2 wheel drive (bad mistake) and the ex stole the other one while I was out of town. Never got it back.

I truly can not complain about my YJ, it has been a damn good car. This is actually the first REAL problem I have had with it. Everything else I have done has been because I wanted to, or as preventative maint.
This wiring issue may end up costing me an arm and a leg, (thanks more than likely to the cowardly theif who felt the need to rip the stereo out of the dash (with out the face plate) and screw up most of the wiring)
With 83K miles on a 93, and no car payment, You would be hard pressed to convince me to even trade it in for a new one even if I was given a massive trade in on it!

The problem with your guages is possibly in the gauge cluster itself. It only takes a couple of screws to get it out. Pull it out and take it apart. I found corrosion under the plastic wing nuts that attach the leads to the gauges on mine. Worth a shot before you pay someone.

Okay this is getting ridiculus!
Sending units are operating with in guidelines (according to how many ohms they are to be sending out)
Fuses and fuse panel are all fine.
Plopped in new gauges, and they worked fine, for about 30 seconds, and then right back to where I was to start with.
There has GOT to be a wiring issue somewhere between the fuse panel, and the gauge cluster. (not really looking forward to digging into that).
The only thing I can think of is the fact that 6 months ago some one tried to help themselves to the cheap stereo I had in the jeep, and made a real mess of the in dash wires, but at the time, it appeared all that was damaged was the stereo/ speaker wires, along with a wire that fed juice to the lights mounted on the windsheild tabs.
So I guess my next step is to put the voltometer into the plug sockets that clip to the back of the gauge cluster. At least at that point, if I find anything, I will know exactly which wires to check from the cluster back to the fuse panel.
At this point,I think it would be easier to put her out to pasture and pick up a early 2000's model, take what I can off of the 93, and go from there.
