aye yai yai....STOP throwing money and parts at them. If you replace 99 out of 100 parts, but don't replace the one part thats broken...it'll still be broken. with sensors you don't know if they're broken till you test them using a multi-meter which can be had for $40 or something cheap...then you can test all the sensors that might be causing the issue and fix whatever is wrong

I have a 1994 jeep grand cherokee with 4.0. I have replaced cps , coil, ox sensor, New grounds on battery. exhaust sytem. The jeep would just die. Discovered it would lose spark and shutdown. My neighbor is a mechanic and suggested that I reset the alarm system. I did this by locking and unlocking driver door twice. Spark came back up and the engine started fine. I read online that adding a ground to the system might help. Look on driver side under dash on left side of steering colume. You will find 2 20 pin connectors. One of the wires is purple with yellow stripe. Attach blue connector and wire to ground under dash. Another issue that I have read about is rusty wires under fuse block under hood. Check this area and all of your grounds. Gounding is a big issue on the older jeeps. Good luck
