1999 Jeep Cherokee with no oil pressure when warm or when idling?
when i start my Jeep the oil pressure is a little lower than normal, as it warms the pressure drops, eventually to zero and the check guages light comes on. When I accelerate the check guages light shuts off and the pressure rises slightly, only a little bit! I have plenty of oil, and I had it changed 3000 miles ago. What is my Jeeps problem?

Unfortunately, your engine is at the end of its life. For that model year, and a few surrounding it, Chrysler tried to use softer materials in the camshaft (which drives the oil pump). Unfortunately, they found that to be a bad idea when the cam gears stripped and oil pumps stopped working. Another thing I have noticed with these is that the head cracks and coolant gets in with the oil (also not good). I hate to say it, because I am a big Jeep fan (especially the 4.0L) but yours is about to face expensive repairs.
