I need to know if there are any ill effects of bypassing the AIV on my 91 G20. I got the HS header and am prepping to put it in, they even include the plug! Comments?

The AIV is supposed to aid in idle quality so taking it off could result in an unsteady idle. I took it off my NX and my idle was actually *much* better. It used to stall every now and then but taking the AIV off certianly helped.
