94 voyager dies

I have a 94 Voyager and it starts fine, sounds good, but when I let of the gas, it dies. I was thinking the following:
1: Throttle Position Sensor
2: Idle control valve or
3: Idle air control motor

Any thoughts are greatly appreciated. I'm trying to figure it out before I just start replacing parts.

Clean the throttle body and IAC passage way> Does it do it when cold and warm?

I haven't tried warm, just cold.

I've replaced the Idle control and ERG... a lot of crud.. Cleaned everything out and it still happens. When I take the vacumm hose off the ERG valve, it seems to idle better???? Any thoughts?

Seems like an EGR problem. You should not be getting a vacuum signal to the EGR valve at idle. Work backwards from there- control solenoid/transducer and connections, vacuum hose routing, etc.
