Question about 1998 Jeep Cherokee 4WD
Bought this jeep the last week of January (2012) and it has been an amazing vehicle to me up until the end of May. I was driving no differently than I normally do, on a flat, straight stretch of road when this problem first started to bare its ugly symptoms. The jeep started to shake somewhat violently (front to back fashion, not side to side) in a pattern similar to how fast you can bat your eyelashes. It was as if the drive was locking up and unlocking as fast as you can blink your eyes 10 times. There were no flags from the OBD initially, and i found that if I took my foot off the accelerator, the shaking/jerking would stop for that instance. But after driving it that way for a week and having it stall on me at idle speed if i didn't keep the rpms above 1k, the check engine light finally came on. I got 2 codes. One saying "loss of camshaft crank" and the other indicating that the camshaft signal was lost/intermittent. So I replaced the plugs, wires, dist. cap&rotor, cam sensor, crankshaft position sensor, the ECU and the ignition coil. Nothing fixed the problem. The only thing that returned any success was when I changed the ignition coil. Now, instead of being thrown forward in my seat several times in rapid continuation, it only jerks backwards-like once every 30 to 45 seconds. Same codes from the OBD.
Wow that's a very dramatic thing to have happened to you !! now I cant be specific on the problem , but heres what I suggest , find someone that has a code reader that gives live data views , this can tell you 4 sure if the cam/crank sensor is loosing its signal or instead (what I believe is happing ) maybe the signal is merely out of range , now out of range signals on crank sensors can occur from misaligned sensors , there are a few possible ways this occurs , one its never properly aligned in the first place , second its not got a solid target to see , this can occur if the bearings and slack tensioners are failing on worn out engines , again a live data feed while driving I believe will be the tell all

Quite possible you have a bad ignition coil. As coil heats up it breaks down and will not return to normal till it cools down. Check for spark the next time this happens. If spark is weak or not there, it warrants testing or replacement.

I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.
