I Need An Exorcist !!!!

my 94 s-10 2.2L is in need of an exorcism:evillol: , this all began with a headgasket replacement (sorry azzed ahop didnt tighten all the bolts when it was replaced 5 mos ago), i installed a new headgasket, then discovered a fairly significant fuel leak (no.4 injector pouring...fixed with new o-rings), reinstalled everything, fired her up and ses acreaming (more like a 2 year old, except it is constant and verrrrry loud) this noise from hell is coming from the vacuum module?/intake area......the truck is idling a little rough (vacuum problem most likely, as haynes has nothing more than is already under the hood to diagram the vacuum/emissions system, did i mention haynes SUX!!!), anyone know an exorcist, i'll pay good money to cast the beast out of this truck:angryfire
