Question about 1990 Jeep Cherokee Limited
Check fuel system... filter, pump (do you hear it running) pump relay, Pressure test at fuel rail for pressure retention, running pressure etc, regulator operation. Also make sure IAC valve is clean., EGR valve is operational. With the limited info you have posted, there is a list a mile long of stuff that can cause your problem. Do basic checks such as making sure vacuum hoses are connected & intact & that ign system is functioning properly.
After you have better info, perhaps I can help!!!
