I'm in reverse. I've had this lumina since 1999, the 2nd gen dodge ram I've had for only 2 years. Except the air volume measurement, lack of egr, the way the two engines work is not all that different.

I'm gonna blame this one on the IAC. Was not able to learn and it killed the engine. Will it not idle or will it not run at any rpm?

Your MAP sensor error, I think it can easily be something else, as these circuits are integrated. I've gotten a MAP error without it being the map...

check all connections. there is alot hiding behind the firewall side of the engine. vacuum and electrical. especially that evil 7x CKP on the block, firewall side of the engine... can't even see it unless you are under the car.
