Help!!!

Ok i checked the Idle control valve it looked fine

But today when i started my car it still was bogging down and the lights were flashing. then it just stalled. But after the car warms up it does not do it anymore. i just replaced my headgaskets so that can not be the problems. If someone could help me that would be great i am driving back to maine on tuesday and i do not want my car to die. also could it be a clogged cat or bad MAF sensor. i bled the coolant system after i changed the gaskets and i checked all of the vacuum hoses.

Check the Purge valve lines, they're commonly unhooked and you wont notice
