need help please. bought a b18c1 obd2 gsr engine and wanting to swap it into my 93 eg SI. Intake manifold is missing few parts. 1) EVAP purge control solenoid valve 2) IAB unit. It looks like the whole secondary butterfly section was also removed. Will I still be able to run the swap smoothly without these parts? Will there be engine codes I have to worry about or rough idle? anyone know how to wire this? I am running a chipped P28 that came with the swap.
