Sounds like you probably have a bad vacuum leak somewhere. Maybe you didn't get the intake air tubing installed correctly, the tubing has a crack in it, or you have some other vacuum leak. Have you checked all the vacuum hoses, PCV elbow, EGR valve, etc.?

Only 50/50 that this will signal and only IF you hit the leak..

If you don't have a smoke machine it beats chasing lines and gaskets until you lose your mind. Been there, maybe I still am. Pass the ether!!!
