1989 Jeep Cherokee

Jeep starts fine but will not idle. If I disconnect the vacuum tube to the map sensor, it will idle fine until the thermostat opens up and then it will stall. The map sensor and the ecm are new. The egr valve is not stuck. The fuel pump is also new and the injectors have been serviced.

Hey al,
Your symptoms lead me to say that its possibly a coolant temp sensor.
