I had the exact same problem with the exact same Van. I simply adjusted the throttle cable under the hood. So that instead of trying to idle around 350rpm, it is now idling between 500-550rpm. Hope this helps.
*I did, at first, change the Mass Airflow Sensor and new Air filter. That seemed to help a bit, but I would still get low idle code. And it wouldn't idle until the engine warmed up. After adjusting the Throttle cable, I've had no more issues.

Xterra will not turn on. windows won't roll down, doors stays locked. won't roll over at all. odometer won't come up

Do you get any dash lights when you turn the key on? If not, you could just have a dead battery.

Drove car thru water. Car died instantaly. water was knee deep. Pushed car out of water. will not turn over now.???

when you say it won`t turn over do you mean it tries to turn over with the starter or it won`t start.if you mean it won`t turn over then when it dries out a bit(water has drained from electrical components)try it again.if it still wont then its possible it may have sucked up water into the cylinder.pull the plugs and try to turn the motor over.if it does then this is the problem.if you mean it won`t start then let it dry still for water in a component may cause electrical issues when wet.just suggestions.
