Engine Mechanical problem
2000 Jeep Cherokee 6 cyl Two Wheel Drive Automatic 180000 miles

Oil pressure maintains at 40 while driving down the road and rpm's are up, but when you come to a stop it goes to 0 and check gauges light comes on. We were told to change the oil sending unit, so we have bought that part, but cannot get the old one to unplug. Need to know how to change out this oil snding unit.
