TPI throttle body ports need help I'm losing my mind
I know someone here can help me.
I have an 86 Camino with an L98 TPI MAF vette motor swap.
I'm losing my mind over the vacuum connections on the pass side of the TB.
Top port runs to pass valve cover and there is no vacuum coming in or out
2nd port is open and pulling hard vacuum. (no Evap canister setup for it to run to). If I try and plug this port it will eventually stall out and if I drive it open it seems sluggish. If I swap the top line to the 2nd and keep the top open it halls *** but I know there's too much vacuum pressure since the Pcv valve is whistling.
What do I do to get this right? Do I need to run the 2nd port somewhere?

Top: Cap it off.
Bottom: PCV valve. Try a new valve. Sounds like your might be a little stopped up.
