Ok Im working on installing a weiand intake manifold on a 2000 SS and im having a few problems. First the map sensor doesnt fit tightly into the hole so how is everyone else making them fit? Also the third rear hole is plugged which i believe i need to put a fitting into for the small vacum line to slid onto anyone know what fitting it is and where i can find it. Finally how is everyone sealing these are you just using the supplied gaskets or doing it some other way?
