Won't Idle
 

One of my valve covers had a crack in it, so i had a fried replace them when I was at work, and now it starts and dies real quick. I don't think theres a vacum leak. but don't know what it is. It ran perfect before this.

Make sure the vacuum hose for the map sensor is still hooked up. When I replaced my fpr I forgot to hook up the map sensor and the car would start and die, it also ran pig rich.
