Car wont idle (wont stay on)

[Igknyte]

Whats an AFM and I/C and IACV?

im having similar issues..
sometimes when i turn on my car itll start out fine at 1000rpm
then drop down to 500-600 or lower.. and it will just bounce back and forth.. high low high low.. or itll just die after a couple of bounces..

then if i shut down my car then start it back up again itll be fine..

also other times when im applying my brakes and come to a stop and my car is in neutral my rpms will drop and act as if its about to die then jump back up and begin to bounce.. or sometimes just die...

been wanting some of my friends to look at my car.. i know a few are pretty good with cars.. but most dont know much bout my supra.. a couple of them are cert. mechanics but usually too busy to actually diag my car.. suckss..
