I combined the two threads so that there is only the one thread now.

That happens to me every time I disconnect power and the PCM powers down. So yes it seems to be a relearning the idle thing.

Get the fuel pressure tested, It wouldn't hurt to drive around with it on there either to see if the pressure drops then comes back up. A bad crank sensor can fail(not giving a signal to the pcm) and will cause the engine to die(while driving). Third the plenum gasket fails on these engines and can cause stumbles/backfires and loss of power. Lastly if all others check out your IAC may be on it's way out. This will cause the engine to die after first start.
So what about the driver door buzzer, and the door lock switches not working? wonder why they stopped working when all of this happened.

Door locks should be powered at all times. I think there is a circuit breaker for those..... but, not 100% on that. Do your dome lights come on when you open the doors?

yes the dome lights come on. the buzzer and door locks went out at the same time, are they both fed off the same power?

Not sure. I don't have wiring diagrams for the vans, and if it's a conversion van, all bets are off.

You can try looking them up here, see if its useful.
