99 4.0 Jeep xj no idle

I got a 99 jeep xj,m. It won’t hold a steady idle. It’ll idle at normal for a few seconds then it’ll drop to nearly no idle an then jump to 2k idle. I replaced my idle air control valve, all new spark plugs ,wires, oil change, air filter still won’t hold a idle. Any body know what else could be wrong.
