look for vacuum leak, or the IAC is bad
when starting it goes up to almost 2k then back down to 500 before stalling out. what could be the cause?

not sure how to check for a leak but i had this problem on my 7g and it was the idle air control motor.. its the iac motor if you give it gas 2 keep it at normal idle when u first start it then its fine after like 10 seconds

buy a can of brake cleaner at autozone or one of those, turn the car on and spray it at all the places where air might be scaping.
do you have a stock or aftermarket intake?
If you have aftermarket and your car is an 4 banger, check your intake manifold (The big Black peice of piping behind the engine where the intake connects to, check to see that it has not cracked behind the throttle body {the metal peice between the intake manifold and the intake}) if the car is shutting off, it has to be a pretty big leak which sounds 100% like a broken intake manifold. update us on your findings.

Try another MAF sensor.

if your MAF or any other sensor goes out to cause a rough idle, it would throw a code correct?

I'm having the same problem. Any suggestions websites that sell MAF for 7G Galants. I would just go to the shop, but I've had bad experiences with auto shops around here, so I try to do everything myself.
