I was driving on saturday the check engine light came on. Had the codes read and the result said system to lean. On Sunday drove for about 30 min and parked the jeep. No problems. Was leaving, the 97 Cherokee drove fine and then stalled. Waited for a few minutes. Drove fine and stalled. repeated the process several times. Got it on the highway to blow anything stuck in the system out but instead stalled again. Towed to the dealers and they diagnosedand said that the Crankcase senser was shot. So will see what happens. For those with the ABS issue. Mine was intermitten. Till it stayed on all the time. Found out it was the abs unit. That hurt. expensive.
