I may have a SOHC vtec d16z6 that I can put in to replace my ZC untill I can rebuild it. Not a hard swap but what I am not sure about is the fast idle valve. It is not on the ZC and I am pretty sure it is on the the d16z6. Do I need to wire this up if so to where or can I just leave it off. The car is original an LX same as DX but with PW PL etc.. So it never had this. Everything is wired up for MPFI from the ZC so the swap is pretty strait forward.I know my 88 rex doesn't have it either but the 89 and up do. any light on the subject??
