So as i stated i swapped a 1996 5.0 vortec to a 1998 5.7 vortec. used the 98's pcm and plugged right in to the original wiring harness. its running fine but i do have a couple codes. one is for a o2 sensor and the other is a vacuum leak i was told. is there somethin i looked over while doin the swap? I heard something about i needed another o2? and another catalytic? Help?! Lol
