I had a cracked hose coming out of my IAC creating a vacuum leak.

When my car was idiling weird and/or stalling it was because I had a hole in one of my hoses about three inches long....vacuum problems. I believe it was my pcv hose.

I don't have a fix but on my 01 GT sometimes when I stop and turn of the car and start it back up fairly soon like stopping at the mini mart it stumbles like it is going to die.
