ok people i'm good now...my dumbass friend did'nt scrape all the old gasket off the intake maifold when he put it on the new motor. that was the vaccum leak. the reason im running an obd2 harness on an obd1 motor is cause all i used off the new engine was block and head, the rest came off my b16a2 that was hydro-locked. damn cold air intakes. thanks again everybody for all the ideas.
