Topic: 93 XJ not running good

[78 k550]

Hey All,
Not running good for about a week. mising and worse when warm. Stumble and run rough but not die. Well at stop sign it died and I couldn't get started.
timing is on put it on TDC and rotor was there at #1. Next did compression test.
1=80
2=80
3=75
4=50
5=95
6=90

256,000 mile's she has on her. I got 10 years and 130,000 out of her. Alot of 4wheeling miles also.
one water pump 2 crank position sensors.

All I have now is my Wings for a vehicle. Hope no snow.

shouldn't have more than a 15 psi difference between cyls for a smooth run, but my bet is you've got a dying motor on your hands. have you tried a leak down test? dry then wet? if it leaks down quickly dry, and slowly wet it's a ring sealing problem, if it leaks down fast wet and dry, you're looking at valve work.
