Default 98 Cherokee Sport Starts and runs, let off the gas and it dies

My jeep ran awesome forever then pulling up to a stop light it just died and would turn over but not start. So I replaced the Crank Position Sensor and it will start now and run great, as long as my foot is slightly on the gas.

The second I let off the gas it dies. Is it the valve in the throttle body for the idle?

could be the battery is having issues. Worth getting it tested or swap it out with another one to see.
