Sounds like you have either blown a head gasket, or you have a crack in the head, or in the block.
First step would be to do a compression check on the motor.

I'd hate to break this too you, but if you're both smelling burnt up antifreeze and loosing it at the same time. I'd definitely take a look at the exhaust. Start the motor and let it idle. Watch the exhaust for either water, or steam / whitish smoke. If you're seeing a lot of vapor after the engine is warmed up you're loosing anti-freeze into the engine itself. Most likely due to a blown head gasket or could be as bad as a cracked head (which the windstars were pretty good for), or even the chance of a cracked block.
If it was me, I'd take the van to a good mechanic and have them do a pressure test on the cooling system. If it's loosing pressure then it's definitely a problem. One major overheat can cause a blown head gasket or worse. So, definitely find the cause and problem there.
Also, as for the OBD reading a lean on bank 1, it could be from the O2 sensors reading water vapors in the exaust. It could be clouding a reading and causing such a problem.
Personally, as I've said, I'd run it to a good mechanic who can pressure test your cooling system. It definitely sounds like you have a blown head gasket to me. It could possibly be a cracked head, but more likely towards the gasket. Do the small test I told you with the exhaust. Let it idle and check the exhaust, then even hit the throttle and see if it shows then. If you're smelling anti-freeze out the tailpipe, it's definitely not a good sign.
(Water of course will cause this rough idle as well. It will hurt the combustion process and give you the rough idling.)
I hope this helps, and I hope it's not a major problem. But, I'd definitely find out if it's leaking water into the motor.

Very common fault is head gaskets. causing coolant consumption and bubbles in radiator. Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.

probably not. put aluminum seal in the cooling system and top off antifreeze. you may need a hose or fitting from where you are decribing the leak. if the leak stops with the sealant you are good to go. otherwise take it to a shop and they will tell you. do not tell them you think it is a head gasket.
